Description

201114047 VI. Description of the Invention: [Technical Field] The present invention relates to a solar cell module, a solar cell panel, a method of manufacturing a solar cell module, and a method of manufacturing a solar cell panel, and more particularly to a method for fabricating a film The film of the power generation layer is a solar cell module, a solar cell panel, a method of manufacturing a solar cell module, and a method of manufacturing a solar cell panel. [Prior Art] As a solar cell panel, it is known to form a thin film lanthanide solar cell on a glass substrate having a thickness of about 4 mm and a cross-section of about 1.4 mX and about 1.1 m. [EVA, Ethylene-Vinyl Acetate copolymer, The ethylene-vinyl acetate copolymer and the back cover sheet (PET/AL/PET structure) were hermetically sealed and an aluminum frame was attached. The material cost of the aluminum frame is about 10% to about 20% of the total material cost of the solar panel. Therefore, the aluminum frame is a high-priced material among the materials used in the manufacture of the solar panel. Therefore, in order to reduce the manufacturing cost of the solar cell panel having the above configuration, it is considered effective to omit or simplify the aluminum frame. Specifically, after the back surface of the solar cell panel is disposed, the cover sheet is replaced with a glass substrate, and at least a part of the strength of the aluminum frame is borne by the glass substrate, whereby the aluminum frame can be omitted or simplified (for example, refer to the patent document) 1). Hereinafter, the configuration in which the glass plate is disposed on the front surface and the back surface of the solar cell panel is referred to as a double glass structure. On the other hand, regarding the solar panel in which the back cover sheet or the like is disposed on the back surface, 143757.doc 201114047 exists by inserting the edge portion of the solar cell module into the "j," end portion of the aluminum frame. In the case where the solar cell module is fixed on the aluminum frame, in this case, if the solar cell panel is disposed as an inclined surface, there is a problem that the power generation area of the solar cell panel is reduced. That is, the surface of the solar cell module on the incident side of the sunlight. Forming a step difference with the fixed portion of the aluminum frame, so that moisture and dust easily accumulate on the step on the side of the inclined surface of the solar panel. The moisture and dust shield the incident light incident on the solar panel. Therefore, the portion becomes a reduced portion of the power generation area. In the case of the solar panel having the double glass structure described above, the incident light of the surface of the solar cell module is incident because the frame for supporting the solar cell module is omitted or simplified. A part of the name frame is not placed on the surface. Therefore, moisture and dust do not accumulate on the incident surface of the incident light as described above, and the power generation area does not decrease. [Prior Art Paper] [Patent Document 1] [Patent Document 1] JP-A-61-199674 SUMMARY OF INVENTION [Problems to be Solved by the Invention] Generally, a lamination step of a solar cell module having a double glass structure, The step of sealing the back glass substrate on the light-transmissive glass substrate and sealing the two glass substrates is performed as follows. That is, EVA (ethylene-vinyl acetate copolymer resin) is applied to the formation of the power generation layer. The entire back surface of the translucent glass substrate is disposed such that the power generation layer and the EVA are interposed between the back glass substrate and the 143757.doc 201114047 translucent glass substrate. The light-transmissive glass substrate, the EVA, the back glass substrate, and the like are heated by a hot plate, and pressed to adhere the light-transmitting glass substrate to the back glass substrate, thereby performing a lamination step. The back glass substrate is bonded to the translucent glass substrate by crosslinking of the EVA. For example, in the lamination step, the photoelectric conversion layer, the filling portion, and the like are hermetically sealed to the light transmissive property. When there is a gap between the glass substrate and the back glass substrate, air in the internal space between the transparent glass substrate and the back glass substrate may not be sufficiently exhausted. In this case, air bubbles remain inside the solar cell module. That is, between the light-transmitting substrate and the rear substrate, there is a problem that the air bubbles become a path in which moisture intrudes into the interior from the periphery of the solar cell module, and there is a problem that the long-term reliability of the EVA sealing portion is lowered. In the laminating step, if there is a surface pressure distribution when the translucent glass substrate and the back glass substrate are pressed, EVA may occur from the periphery of the solar cell module, particularly from the corner portion to the outer side. After the end of the pressure, the EVA is retracted to the inside of the solar cell module, so that there is a gap that creates a gap. When this gap is generated, there is a problem in that the sealing property of the eva sealing portion against moisture intrusion is lowered, and the reliability is lowered for a long period of time. Especially in a large-sized solar cell module having an area of more than 1 m2, it is difficult to obtain a state in which the solar cell module is entirely pressed. Alternatively, warpage may occur due to the heat distribution of the substrate, whereby the following situation may occur: jump 143757.doc 201114047 extends from the periphery of the substrate to the outside, or the EVA is retracted to the inside of the solar cell module. Therefore, it is desirable to have measures to effectively obtain a uniform pressing state of the solar cell module as a whole, and to effectively prevent the EVA from extending to the outside and retracting to the inside. Here, in the case where the EVA generated closer to the periphery of the substrate than the center of the substrate protrudes to the outside in the substrate interval between the translucent glass substrate and the back glass substrate, it is considered that the EVA is retracted to the inside as follows. occur. That is, 'the distance between the transparent glass substrate and the substrate of the back glass substrate around the solar cell module, especially the corner portion of the solar cell module by the pressing force in the laminating step, is the entire area mainly centered on the central portion of the solar cell module. The substrate spacing is too close. In this state, if the lamination step is completed and the pressing force is lost, the interval between the translucent glass substrate and the back glass substrate in which the substrate spacing is too close (the corner portion) is widened. And the substrate spacing is close to the central portion of the substrate. Therefore, the EVA disposed between the translucent glass substrate and the back glass substrate is stretched inward and retracted into the peripheral portion of the solar cell module. Here, the end of the lamination step is referred to as a solar cell module, and the end of all manufacturing steps is referred to as a solar cell panel. The present invention has been made to solve the above problems, and an object of the present invention is to provide a solar cell module, a solar cell panel, and a solar cell capable of suppressing the extension and retraction of EVA and suppressing the intrusion of moisture into the solar cell module. A method of manufacturing a module and a method of manufacturing a solar panel. [Technical means for solving the problem] 143757.doc 201114047 In order to achieve the above object, the present invention provides the following mechanism. A first aspect of the present invention provides a solar cell module including: a translucent substrate and a rear substrate, which are disposed with a photoelectric conversion layer interposed therebetween; and an inner sealing portion that is located on the translucent substrate and a door of the back substrate is disposed to surround the periphery of the light-transmitting substrate and the back substrate; and the filling portion is disposed in the region surrounded by the light-transmitting substrate, the back substrate, and the inner sealing portion a gap formed in one of the inner seal portions to connect a region in which the filling portion is disposed to the outside; and an outer seal portion covering the gap. According to the ith aspect of the present invention, since the filling portion is disposed in the space surrounded by the "sealing portion" on the light-transmitting substrate, the rear substrate, and the inside, the space in which the filling portion is sealed is sealed in a sealed manner. The filling portion can be prevented from projecting from between the light-transmitting substrate and the back substrate. Further, since the inner sealing portion is disposed between the light-transmitting substrate and the rear substrate, it is possible to maintain the suppression characteristics of suppressing the intrusion of moisture components into the solar cell module, that is, the region in which the photoelectric conversion layer is disposed. On the other hand, when the photoelectric conversion layer, the filling portion, and the like are hermetically sealed between the light-transmitting substrate and the back substrate, the light-transmitting substrate, the rear substrate, and the inner side can be formed through the gap formed in the inner sealing portion. The air in the space surrounded by the sealing portion is exhausted. Therefore, it is possible to prevent air bubbles from remaining in the solar cell module.卩, that is, between the light-transmitting substrate and the back substrate. Thereby, it is possible to suppress the long-term reliability of the solar cell module by suppressing the bubble from entering the inside of the solar cell module to the inside. Further, after the photoelectric conversion layer, the filling portion, and the like are sealed between the light-transmitting substrate and the back substrate of 143757.doc 201114047, the outer periphery of the gap is covered by the outer peripheral sealing portion, thereby ensuring the sealing property of the inside of the solar cell module. . In the first aspect of the invention described above, it is preferable that the gap is provided only at one of the inner seal portions. According to the present invention, for example, when the solar battery module of the present invention is placed on the inclined installation surface, the solar battery module is disposed such that the gap of the inner seal portion is disposed on the upper side of the inclined installation surface, thereby suppressing (iv) The component intrudes into the interior of the solar cell module. Water such as rainwater invades between the solar cell module and the frame that holds the solar cell module. The solar cell module is disposed on the inclined setting surface. When the solar cell panel is disposed and the drainage structure is formed, when moisture is retained in the lower side of the solar cell panel, moisture accumulates below the inclined surface. Therefore, the inner side of the water tray can be separated from the gap of the seal portion by arranging the gap of the inner seal portion on the upper side of the inclined installation surface. The potted fruit, for the accumulated water, inhibits the intrusion of moisture components by the seal of the inner seal of the sequel, and the inside seals the water... The gap between the β is located in the gap of the seal It is possible to prevent moisture components from intruding into the interior of the solar cell module by being kept away from the accumulation and covering the gap by the outer seal portion. In the red aspect of the above invention, it is preferable that the gap is a corner portion of the inner seal portion. According to the present invention, the inner seal portion is disposed by the inner seal. The angle (4) is a gap and can be stabilized. For example, when using a dispenser or the like, the inner seal is disposed on the main fabric of the squirrel &

'; the corner of the upper cloth changes, % &amp; 〇P Zhao coated inner seal 143757.doc 201114047 The thickness is not uniform, the corners of the part form the seal ', therefore, sex. Or the shape of the inner seal portion is not uniform. If the gap is sealed inside, it is not necessary to arrange the thickness and shape of the inner dense portion (4) at the corner where the construction is difficult. On the other hand, the light-transmitting substrate is air-exhausted from the ground by the respective corner portions. Since the gap between the inner seal portions is provided in the inner seal portion, the space surrounded by the rear substrate and the inner seal portion can be equalized as compared with the case where the inner seal portion is provided only in one place, so that the bubbles can be prevented from remaining in the sun. The inside of the battery module, that is, between the light-transmitting substrate and the back substrate, can prevent the bubble from becoming a path from the periphery of the solar cell module to the inside, thereby improving the long-term reliability of the battery module. In the first aspect of the invention, it is preferable that the inner side seal portion is disposed on one side of the opposite side of the light-transmitting substrate and the back surface substrate, and the other two sides are opposite to each other. The above gap is configured on the other side. According to the present invention, since the inner seal portion is disposed only on the opposite sides, the arrangement and construction of the inner seal portion are facilitated. For example, when the inner seal portion is applied by the dispenser, the direction of movement of the dispenser is restricted, so that the drive mechanism of the dispenser can be simplified. A second aspect of the present invention provides a solar battery panel provided with the solar battery module according to the first aspect of the present invention, and a rib fixed to the rear substrate of the solar battery module to support the above According to the second aspect of the present invention, the solar battery module is fixed to the rear substrate and supports the sun 143757.doc 201114047 The rib of the battery module functions as a member for increasing the strength of the solar battery module. Therefore, even if the strength of the back substrate itself is low and the back substrate can be thinned, the material cost of the back substrate can be lowered. Further, by thinning the back substrate, even if the weight of the rib is increased, the solar panel can be made lighter, and the usability of the solar panel during the manufacturing process can be improved. A third aspect of the present invention provides a method of manufacturing a solar cell module, comprising: a film forming step of forming a photoelectric conversion layer on a light-transmitting substrate; and a step of arranging the periphery of the light-transmitting substrate a side seal portion ′ is disposed, and a gap having a notch shape is formed in one of the inner seal portions, and a filling portion is disposed in a region surrounded by the inner seal portion; and a sealing step of arranging the back substrate and the back substrate The inner seal portion and the filling portion are interposed between the light-transmitting substrates, and the inner side is sealed. The air in the space surrounded by the crucible is exhausted, and the filling portion is heated and sealed to seal the translucent substrate and the back glass substrate. According to the third aspect of the present invention, in the disposing step, the filling portion is disposed in the space surrounded by the translucent substrate, the rear substrate, and the inner sealing portion, so that the filling portion can be prevented from being between the translucent substrate and the rear substrate. Extend. Further, since the inner sealing portion is disposed between the light-transmitting substrate and the rear substrate, it is possible to maintain the suppression characteristics in which the moisture component is prevented from entering the inside of the solar cell module, that is, the region where the photoelectric conversion layer is disposed. On the other hand, in the sealing step of sealing the photoelectric conversion layer and the filling portion between the light-transmitting substrate and the back substrate, the light-transmitting substrate and the back surface can be formed via the gap formed in the inner sealing portion M3757.doc 201114047. The air in the space surrounded by the substrate and the inner seal portion is exhausted. Therefore, it is possible to prevent air bubbles from remaining inside the solar cell module, that is, between the light-transmitting substrate and the rear substrate. Thereby, the bubble is suppressed from becoming a path in which moisture intrudes into the interior from the periphery of the solar cell module, thereby improving the long-term reliability of the solar cell module. A fourth aspect of the present invention provides a method of manufacturing a solar cell module, comprising: a film forming step of forming a photoelectric conversion layer on a light-transmitting substrate; and a disposing step of covering the light-transmitting substrate a filling portion is disposed in the photoelectric conversion layer; and a sealing step of disposing the back substrate, and the photoelectric conversion layer and the filling portion are interposed between the back substrate and the light-transmitting substrate; a restricting portion that is spaced apart from the back side of the substrate and disposed on the second 〇P-knife around the light-transmitting substrate, and the arranging hole between the light-transmitting substrate and the back substrate The portion is heated and sealed to seal the light-transmissive substrate and the back glass substrate. : The fourth aspect of Kang Ben Mao Ming, the distance between the light-transmitting substrate and the back substrate; the spacing of the material from the restraint is narrower. Therefore, in the anti-sealing step, the filling portion is pushed out from between the light-transmitting substrate and the rear substrate, and the gap between the light-transmitting substrate and the rear substrate is not changed. </ RTI> can prevent the filling portion from shrinking to the path of the transparent substrate and the back portion, and invading from the periphery of the solar cell module to the long-term reliability of the two solar cell modules. 143757.doc 201114047 On the above-mentioned date of the sun. ^ In the third aspect or the fourth aspect, the phase difference is different, and the sealing step includes a peripheral sealing step of the above-mentioned sealed outer sealing portion of the dispensing &amp; v core, and the outer sealing portion is located at Shangcheng. The outer circumference of the inner seal portion between the 1J^31 light-transmitting substrate and the rear substrate is covered. According to the present invention, after the step of sealing the photoelectric conversion layer or the like between the light-transmitting substrate and the rear substrate, the outer peripheral sealing portion covers the outer periphery of the transparent substrate and the rear substrate without the inner sealing portion. Therefore, the internal sealing of the solar cell module can be ensured. A fifth aspect of the present invention provides a method of manufacturing a solar panel, which is further characterized by the above-described sealing step in the method of manufacturing a solar cell module of the present invention, further comprising a rib mounting step, the rib mounting step A rib supporting the solar cell module is mounted on the rear substrate. According to the fifth aspect of the invention, the ribs fixed to the rear substrate and supporting the solar battery module can function as a member for increasing the strength of the solar battery module. Therefore, even if the strength of the back substrate itself is low, and the back substrate can be thinned, the material cost of the back substrate can be lowered. Further, by making the back substrate thinner, even if the weight increase portion of the rib portion is estimated, the solar cell panel can be made lighter, and the usability of the solar cell panel at the time of manufacture or installation can be improved.

The light-transmitting substrate, the rear substrate, and the inner sealing portion can be formed through the gap formed in the inner sealing portion I43757.doc 12 201114047. Since the air in the enclosed space is exhausted, it is possible to suppress the extension and retraction of the filling portion (EVA or the like) and to suppress the intrusion of moisture into the solar cell module. According to the method for manufacturing a solar battery module according to the fourth aspect of the present invention and the method for manufacturing a solar panel according to the fifth aspect of the present invention, the restricting portion for defining the interval between the light-transmitting substrate and the back-side glass substrate is disposed to transmit light. Since the substrate and the backside glass substrate are sealed, it is possible to suppress the protrusion and retraction of the filling portion (EVA or the like) and to suppress the intrusion of moisture into the solar cell module.

However, when the necessary strength of the solar panel 1 is secured, the number of the long side ribs 3L and the short side ribs 3S is set. It is not limited to the number of pairs. In the present embodiment, the cross-sectional shape of the long-side rib 3L and the short-side rib 3S is formed in an I-shape. However, when the required strength of the solar panel 1 is secured, the shape is not limited to the I-shape. Shape profile.

Therefore, the back substrate 丨j b can be made thinner than the case where the long side rib 3L and the short side rib 3S are not used, even if the strength of the back substrate 11B itself is low. Therefore, the material cost of the back substrate i 1B can be lowered, and the manufacturing cost of the solar cell panel 1 can be reduced. Furthermore, by thinning the back substrate 11B, even if the weight increase of the long side ribs 3L and the short side ribs 3S is estimated, the weight of the solar panel i can be reduced and the weight can be reduced, and the sun can be made.

By the arrangement of the solar panel 1 and the drainage structure, when the moisture retaining region is generated on the lower side of the solar panel 1, the water accumulates on the inclined surface. Below. Therefore, by arranging the gap of the inner circumferential sealing material on the upper side of the inclined installation surface, the accumulated water can be separated from the gap 26C of the inner circumferential sealing material 26A. As a result, the intrusion of the wet component is suppressed by the sealing structure of the continuously formed inner peripheral sealing material 26A.

In the present embodiment, heating to about 150 is applied. (The temperature is not particularly limited. The transport unit 254L transports the translucent substrate 11A and the rear substrate 11B between the substrate and the substrate transport roller 270. The transport unit 254L is provided in the transport unit 254L. The conveyance belt 256L which is disposed in a ring shape around the lower chamber 252L, and the belt roller 257L which supports the conveyance belt 256L. The conveyance belt 256L is placed on the light-transmissive substrate 11a and the rear substrate 11B, and the lower chamber is placed. The belt 257L is configured to rotate the belt 257L around the lower chamber 252L to support the conveyor belt 256L. The sleeper 255L is pressed against the belt 257L. In the case of the light-transmitting substrate ha and the back substrate 11B, the space between the light-transmitting substrate 11A and the back substrate 11B is defined. The sleeper 255L is formed into a substantially prismatic member, and is disposed in the upper half 25 1U and the lower half 25 The height of the sleeper 255L in the upper and lower directions (the upper and lower directions in FIG. 20) is obtained by adding the thickness of each of the light-transmitting substrate 11A and the back substrate 11B to the space between the light-transmitting substrate 丨ia and the back substrate 11B. Size. A method of using the light-transmissive substrate 11A and the back surface 143757.doc • 37-201114047 substrate 11B of the above-described laminating machine 250 will be described. First, as shown in FIG. 19, light-transmitting is formed on the photoelectric conversion layer 13 or the like. On the upper surface of the substrate 11, the waterproof material 21, the copper foil terminal 22, the insulating sheet 24, the steel foil terminals 22, 23, and the subsequent filling material sheet 25, and the back substrate 11 (the arrangement step) are disposed. When the hole is removed, it is not necessary to suppress the intrusion of moisture or the like from the outside, or when it is not necessary to suppress the heat influence at the time of joining by solder or the like, the water-repellent material 21 may be omitted. Further, the step before the arrangement step and the first embodiment The description will be omitted. The transparent substrate 丨 a and the back substrate 11B, which are placed next to the filler sheet 25, are transported to the stacker 250 by the substrate transport roller 270 as shown in FIG. The light-transmissive substrate 1A and the back substrate 11B on which the underfill material sheet 25 and the like are disposed are disposed between the lower half 251L and the upper half 251U by the transport portion 254L of the stacker 250. The sleeper 25 5L is disposed adjacent to the light-transmitting substrate 11A and the back substrate 11B. The sleeper 25 5L is provided around the light-transmitting substrate 11A and the back substrate 11B, but is particularly preferably disposed at a central portion of the corner or the long side. Further, the upper half 251 U is brought close to the lower half 25 1L, so that the upper chamber 252U and the lower chamber 252L are in close contact with each other, whereby the light-transmitting substrate 11A and the rear substrate on which the filling material sheet 25 or the like is placed are disposed. 11B is housed inside a confined space. I43757.doc • 38-201114047 The upper vent hole portion 261U and the lower vent hole portion 261L are opened while the light-transmitting substrate 11A and the back substrate 11B on which the filling material sheet 25 is placed are disposed. In other words, the upper space US is open to the atmosphere, and the closed space of the upper chamber 252U and the lower chamber 252L is also open to the atmosphere. Next, the air inside the light-transmitting substrate 11A and the back substrate 11B is evacuated, pressed, and heated. The pressing of the light-transmitting substrate 11A and the back substrate 11B is specifically performed as follows. In other words, the upper vent hole portion 26A and the lower vent hole portion 261L are closed, and the upper vacuum exhaust portion 262U and the lower vacuum exhaust portion 262L are opened, and the upper space us and the closed space are opened by the vacuum pump. The air is exhausted. Thereby, degassing between the light-transmitting substrate 11A and the back substrate 11B is performed. Further, only the upper vacuum exhaust portion 262U is closed, and the upper vent portion 261U is opened again. Thereby, the inside of the upper space u S is boosted to the atmospheric pressure, and the diaphragm pressed piece 253U is pushed toward the light-transmitting substrate 11A and the rear substrate 11B by the pressure difference between the upper space US and the sealed space. In other words, the light-transmitting substrate 11A and the back substrate 11B are pressed by the back substrate 11B pushed by the film pressing sheet 253U. On the other hand, the translucent substrate 11A and the rear substrate 11B are strongly pressed in the direction of the hot plate 253L. Therefore, the heat of the hot plate 253L is transmitted to the subsequent filling material sheet 25 via the conveyance belt 256L and the translucent substrate 11A. . Thus, the back substrate 11B and the light-transmitting substrate 11A are adhered to each other, and the back substrate 11B and the light-transmitting substrate 11A are then sealed and sealed by cross-linking the EVA of the filler material sheet 25 following the 143757.doc-39-201114047 ( Sealing step). At this time, the translucent substrate 11A and the back substrate η B are pressed to the latitude of the sleeper 25 5 L, and thereafter, the diaphragm pressed sheet 253U is supported by the sleeper 255L. When the light-transmissive substrate 11A and the rear substrate 11B are closed to the right, the lower vacuum exhaust portion 262L is closed, and the lower vent hole portion 261L is opened to introduce the atmosphere into the sealed space. Thereby, the pressing of the back substrate 11B by the diaphragm pressed sheet 253u is completed. Thereafter, the upper half portion 251lJ moves upward and away from the lower half portion 251L. At this time, since the release sheet 254U is disposed in a portion where the translucent substrate ha of the upper half 251U and the rear substrate 11B are in contact with each other, the translucent substrate 11A, the rear substrate 11B, and the upper half portion 25 1U are not extended. EVA followed. Further, the self-stacking machine 250 removes the sleepers 255L disposed adjacent to the translucent substrate 11A and the rear substrate 11B, and transports the translucent substrate 11A and the rear substrate ΠΒ to the substrate transport roller 270 by the transport unit 254L. The translucent substrate 11A and the rear substrate 11B are carried out. Fig. 2 is a schematic view showing the steps of coating the outer sealing material. Fig. 22 is a schematic view showing a construction state different from the construction state in the outer side sealing material of Fig. 21. When the back substrate 11B is attached to the light-transmitting substrate 11A, as shown in Fig. 21, the outer peripheral sealing material 26B is disposed so as to cover the space between the light-transmitting substrate 11A and the rear substrate 11B from the outside (outer circumferential sealing step). Further, the outer peripheral sealing material 26B is not only 143757.doc • 40- 201114047 on the side end of the light-transmitting substrate 11A but is formed as shown in Fig. 22, and the entire P-blade is applied to the side end of the rear substrate 11B. Further, the crucible may be applied in such a manner that a small amount is wound around the side of the back substrate to improve the sealing property. At this time, in order to prevent the arrangement of the long side ribs 3L from being formed, the construction is performed in consideration of the amount of the rounding. The outer peripheral sealing material 26B is sealed between the translucent substrate 11A and the rear substrate 11B to ensure a higher sealing property of the solar cell module 2〇2, and further prevents water and moisture components from intruding into the solar cell module. The inside of the group. Further, the subsequent steps are the same as those of the third embodiment, and the description thereof will be omitted. According to the above configuration, the substrate 15 between the translucent substrate 11A and the back substrate 11B is not narrower than the sleeper (5) at a predetermined specific interval by the pressing force in the laminating step, so that the filling can be prevented in the sealing step. The material sheet 25 is pushed out from between the light-transmitting substrate UA and the back substrate UB. Here, as a specific interval defined above, for example, 〇 3 right to about 1.0 mm may be mentioned. The substrate spacing necessary for a specific interval can be set with an accuracy of approximately ± 0.1 mm, depending on the thickness of the succeeding material sheet 25 and the pressing condition 4 in the laminating step. Further, after the sealing step is completed, if the pressing force is lost, the substrate interval of the non-transparent substrate 11A of the moon-surface substrate 11B is closer to the predetermined interval than the predetermined interval, and the interval is not widened. Therefore, it is possible to prevent the filling material sheet 25 from being retracted between the light-transmitting substrate UA and the back substrate 11B, thereby preventing the retraction of the filling material sheet 25 from occurring in the peripheral portion of the solar battery module 2. 143757.doc • 41 · 201114047 Therefore, it is possible to suppress the intrusion of moisture from the periphery of the solar cell module 2 to the inside, thereby improving the long-term reliability of the solar cell module 2. [Fourth embodiment] Next, a fourth embodiment of the present invention will be described with reference to Fig. 23 . The basic configuration of the solar cell panel of the present embodiment is the same as that of the third embodiment, but differs from the third embodiment in that a method of attaching a light-transmitting substrate and a rear substrate of a laminator is used. Therefore, in the present embodiment, only the method of attaching the translucent substrate to the rear substrate using the laminator will be described with reference to Fig. 23, and other components and the like will be omitted. Fig. 23 is a schematic view showing the configuration of the laminating machine of the embodiment. The same components as those in the third embodiment are denoted by the same reference numerals, and their description will be omitted. The laminating machine 350 is used for the carrier of the translucent substrate 11A and the back substrate 11B. The superimposer 350 is provided with an upper half 25 1U and a lower half 351 and a lower half 351L as shown in FIG. The air venting inside the light-transmissive substrate UA and the back substrate 11]B between the lower half 3511 and the upper half 251IJ is followed by pressing and heating. seal. The lower half 351L is disposed between the substrate conveyance rollers 270 and 270, and is configured to transport the translucent substrate 1 ia and the lunar substrate between the lower half 35 1L and the substrate conveyance roller 270. Configuration. The lower chamber 351L is provided with a lower chamber 252L, a hot plate 253L, a conveying portion 254L, and a spacer (restricting portion) 355L. The spacer 355L is for pressing the transparent substrate 11A and the rear substrate ι1 143 143757. doc - 42 - 201114047 to define the interval between the light-transmitting substrate 1 i A and the rear substrate i 丨 B. The intermediate member 355L is disposed between the upper half 25 ι and the lower half 351L. The spacer 355L' is provided with a protruding portion 356L that protrudes in the horizontal direction (the horizontal direction in Fig. 23) in a state of being disposed between the upper half 251U and the lower half 351L. The large portion 356 is inserted between the translucent substrate 丨丨a and the back substrate 丨丨b, and the space between the translucent substrate 11A and the rear substrate 11B is defined. Therefore, the dimension in the upper and lower directions of the protruding portion 356L (upward and downward in Fig. 23) depends on the interval between the light-transmitting substrate 11A and the back substrate 丨1B. Next, a method of attaching the light-transmitting substrate U A and the back substrate 11B using the above-described laminating machine 35 will be described. The translucent substrate 丨丨A and the back substrate 11B on which the underfill material sheet 25 and the like are disposed are disposed between the lower half 35 1L and the upper half 25 1U by the transport unit 254L of the stacker 350. Since they are the same as those of the third embodiment, their description will be omitted. The spacer 355L of the present embodiment is disposed differently from the sleeper 255L of the third embodiment in such a manner that the protruding portion 356L is inserted into the gap between the light-transmitting substrate 11a and the back substrate 11B. Further, the spacer 355L is disposed on the entire circumference of the light-transmitting substrate 11A and the rear substrate 11B, but it is particularly preferable to arrange it in the vicinity of the central portion of the corner portion or the long side. Thereby, when the light-transmitting substrate 11A and the back substrate 11b are pressed, the light-transmitting substrate 11A and the rear substrate 11B are close to each other until the opposing faces are in contact with the protruding portion 356L. After the light-transmitting substrate 1A and the back substrate 11B are in contact with the protruding portion 356L, even if the back substrate 11B is pressed by the film 143757.doc • 43 · 201114047 pressed sheet 253U, the light-transmitting substrate 11A is not further contacted. Since the subsequent steps are the same as those in the third embodiment, the description thereof will be omitted. According to the above configuration, the interval between the translucent substrate 11A and the rear substrate 11 b is not narrower than the specific interval defined by the protruding portion 356L of the spacer 355L, so that the adhesive material sheet 25 can be prevented from being self-transmissive in the sealing step. 11A and the back substrate 11B are pushed to protrude. Further, after the sealing step is completed, if the pressing force is lost, the distance between the translucent substrate 11A and the rear substrate 11B is not widened, so that the underfill material sheet 25 can be prevented from being retracted into the translucent substrate UA and the rear substrate. Between 11β' and the retraction of the filling material sheet 25 is prevented from occurring in the peripheral portion of the solar cell module 2. Therefore, it is possible to suppress the intrusion of moisture from the periphery of the solar cell module 2 to the inside, thereby improving the long-term reliability of the solar cell module 2. [Fifth Embodiment] Next, a fifth embodiment of the present invention will be described with reference to Fig. 24 . The basic configuration of the solar cell panel of the present embodiment is the same as that of the second embodiment, but the arrangement position of the inner circumferential sealing material is different from that of the third embodiment. Therefore, in the present embodiment, only the arrangement position of the gap in the inner circumferential sealing material will be described with reference to Fig. 24, and the description of other components and the like will be omitted. Fig. 24 is a schematic view showing the arrangement position of the gap of the inner circumferential sealing material of the solar cell panel of the present embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted. The inner circumference of the solar cell module of the solar cell panel 301 of the present embodiment 143757.doc -44 - 201114047 The arrangement of the sealing material (inner sealing portion) 326A is as shown in FIG. One of the long side and the short side of the corpse/σ translucent substrate 11A is provided with an inner peripheral sealing material 326Α. In other words, a gap 326C is disposed across the entire other of the long side and the short side. The inner circumferential sealing material 326 is the same as the inner circumferential sealing material 第 of the i-th embodiment, and prevents the adhesive material sheet 25 from extending from the light-transmitting substrate 丨1Α and the back substrate 11B to the outside. Further, the inner circumferential sealing material 326a is a sealing material containing the same material as the inner circumferential sealing material 26A of the first embodiment. According to the above configuration, the inner circumferential sealing material 326A is disposed only on one of the long sides and the short sides of the light-transmitting substrate 11A, that is, the inner circumferential sealing material 326A is easily disposed. When the inner circumferential sealing material 326A is applied by the dispenser as in the present embodiment, the moving direction of the dispenser is restricted, so that the driving mechanism of the dispenser can be simplified.
