Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a solar cell module containing solar cells.

[0002]

2. Description of the Related Art Photovoltaic power generation systems control the pollution of air due to the use of fossil fuels such as petroleum, environmental damage due to acid rain, and the generation of carbon dioxide that causes global warming. It is attracting attention as a promising energy supply system because it is safer and more environmentally friendly. In addition to the conventional stand-alone power generation system, so-called grid-connected small-scale systems that are installed on the roofs of private houses, etc. and are connected to the commercial power system are also becoming widespread. The demand for power generation systems tends to continue to grow.

In this solar power generation system, since the solar cells are installed outdoors for a long period of time, solar cell modules having weather resistance and mechanical strength have been manufactured to protect the solar cells. As a typical example of a solar cell module for residential use, there is a super straight type solar cell module.

The super straight type solar cell module is manufactured by a so-called laminating method in which pressure molding is performed while heating in a vacuum, and a dedicated laminating apparatus is used for this method. The components of the solar cell module are
As shown in FIG. 8, a glass substrate 1 as a supporting substrate and sealing resins 2a and 2b as fillers (collectively,
It is called "sealing resin 2." ), The solar cell 3 and the back surface protective film 4 which have completed the electrical wiring, and the molded body 10 integrated with these is formed. The laminating apparatus includes a mounting table on which the molding target 10 is mounted, an opening / closing table that can be opened and closed, a vacuum device, and a heating device. The opening / closing table has two upper and lower spaces sandwiching a boundary sheet made of heat-resistant rubber or the like (hereinafter, these two spaces are referred to as “upper layer” and “lower layer”).

A procedure for manufacturing a solar cell module by the laminating method will be briefly described. The molded body 10 is set on the mounting table. That is, with the glass substrate 1 facing downward, the sealing resin 2a having a size larger than the glass substrate 1, the solar cell 3, the sealing resin 2b, and the back surface protective film 4 having a size larger than the sealing resin 2b are sequentially arranged on the glass substrate 1. Place it. When the solar cell module is actually used, sunlight is emitted from the glass substrate 1 side.

Next, the opening / closing table is closed to seal the lower layer, and both the upper layer and the lower layer are degassed to a vacuum state. After a predetermined time has passed, air is enclosed only in the upper layer. Thereby, pressing (1 atm) in a vacuum state is performed, and uniform pressure is applied from above the back surface protective film 4 in the lower layer,
As shown in FIG. 9, the sealing resin 2, the glass substrate 1, and the solar cell 3 are in close contact with each other. Then, when further heated in an oven or the like to improve the adhesiveness of each, the sealing resin 2 is crosslinked.

Next, in this molded body 10, the sealing resin 2 and the back surface protective film 4 protruding outside the glass substrate 6 are removed by a hot cutter. Further, as shown in FIG. 10, a sealing material 41 such as butyl rubber is wrapped around the peripheral portion of the molded body 10 in order to provide moisture resistance and insulation. The frame frame 4 made of aluminum or the like is used to increase the strength of the entire solar cell module.
Attach 2.

As described above, in the solar cell module manufactured by the conventional method, the sealing member wound around the peripheral portion of the molded body 10 prevents the invasion of water vapor into the module. Thereby, the deterioration of the performance of the solar battery cell 3 and the deterioration of the material of the constituent members were prevented.

[0009]

However, considering that the solar cell module is used for a long period of time, the above-mentioned conventional sealing structure is not sufficient.
That is, further lowering the water vapor permeability into the inside of the solar cell module is an important issue for long-term use, and for that purpose, it has been necessary to improve the sealing performance at the peripheral portion of the solar cell module.

Further, in the conventional laminating method, in order to wrap the sealing material around the peripheral portion of the molded body, the work of cutting the sealing resin and the back surface protective film protruding from the glass substrate is always performed. Since this work requires labor and time, it has been desired to simplify the work and shorten the work time.

Here, as a technique for solving the drawbacks of the conventional laminating method, Japanese Patent Laid-Open No. 6-61518 discloses:
A solar cell module is disclosed in which a sealing resin is applied to improve the sealing performance of the peripheral edge. However, since the encapsulant is applied, it may wrap around to the back surface of the substrate, impede the incidence of light, and reduce the performance of the solar cell. Therefore, a treatment for preventing this is required, which increases the number of manufacturing processes and impairs productivity.

In view of the above, it is an object of the present invention to provide a method of manufacturing a solar cell module, which can further improve the sealing performance and can be manufactured without impairing the productivity in manufacturing the solar cell module by the laminating method. And

[0013]

A method of manufacturing a solar cell module according to the present invention is a method of manufacturing a solar cell module by pressure-molding a molding object in which a light-transmitting material, a sealing material, a solar cell and a protective material are laminated. At the time of manufacturing, the peripheral edge of the member on the surface of the molding target is pressure-contacted for lamination, so that the protective material is pressure-bonded to the translucent material via the sealing material. Then, the sealing material is laminated so that the thickness of the peripheral portion is smaller than the thickness of the central portion. By this method, it is possible to prevent the infiltration of water vapor from the peripheral edge of the molded body into the inside.

A frame is used for press-contacting the peripheral edge of the molded body. The frame body is formed of a heat-resistant material so as to surround the peripheral edge of the molded body, and has an opening larger than the region where the solar battery cells are arranged. . With such a frame body, the peripheral edge of the molding target can be easily pressure-welded, and since the frame body is made of a material having heat resistance, deterioration due to heat,
It has no deformation and is suitable for mass production of solar cell modules. Furthermore, by arranging the solar battery cells in the openings, the solar battery cells are not damaged when they are pressed against each other.

Further, in order to prevent the sealing material from protruding, the size of the sealing material is made smaller than that of the transparent material and the protective material, or the size of the protective material is made the same as that of the transparent material, so that the laminate is laminated. It may be performed. In this way, since the encapsulating material and the protective material do not protrude to the outside of the molding target after laminating, the step of cutting the encapsulating material and the protective material, which has been conventionally performed, can be omitted. The above dimensions refer to the vertical width and the horizontal width of the member.

Further, the mounting table on which the molded body is mounted and the mounting table on which the frame is mounted are moved relatively to each other so that the two tables are brought into contact with each other and laminated to form a sealing material as a light-transmitting material. Adhere to solar cells and protective materials. By doing so, it is possible to save the trouble of setting the molding target on the frame one by one, and also the positioning of the molding target is facilitated, and the molding target can be efficiently placed on the mounting table. .

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 2 is a diagram showing a solar cell module manufactured by the method for manufacturing a solar cell module according to one embodiment of the present invention. The components of the solar cell module include a transparent substrate 1 as a transparent material, a sealing material 2, a plurality of solar cells 3, and a back surface protective film 4 as a protective material.
Consists of.

As the translucent substrate 1, white plate tempered glass is used. In particular, the translucent substrate 1 is preferably made of a material having good light transmittance, excellent weather resistance, being resistant to scratches and dust, and having a low water vapor transmission rate. Instead of glass, acrylic, polycarbonate, silicon, fluororesin, or the like may be applied.

The sealing material 2 is a sheet-like E having excellent moisture resistance.
VA resin (copolymer of ethylene and vinyl alcohol)
Is used. The sealing material 2 is more preferably a material having excellent light transmittance, good adhesion to the solar cell 3 and other constituent members, and high insulation resistance. Instead of EVA resin,
You may use PVB (Polyvinyl Butyral) or silicone etc. with little ultraviolet deterioration.

As the back surface protective film 4, a sheet having a structure in which aluminum is sandwiched between PVF (Polyvinyl Fluoride) films is used. The back surface protective film 4 is lightweight,
Higher insulation resistance and lower water vapor transmission rate are more desirable. A polyester or acrylic sheet or the like may be used instead of the PVF film.

FIG. 3 is a sectional view showing a laminating apparatus for manufacturing a solar cell module having such a structure. The laminating apparatus 5 has a mounting table 6 on which each component of the solar cell module is mounted, and a mounting table 8 which is provided so as to be openable and closable with respect to the mounting table 8 for mounting the frame body 7. The frame 7 is used to press the peripheral edges of the constituent members.

A sample table 9 is fixed on the upper surface of the table 6, and each component of the solar cell module is placed on the sample table 9. As shown in FIG. 1, the mounting order is, as shown in FIG. 1, a light-transmissive substrate 1, a sealing material 2a, a solar battery cell 3 after a plurality of electrical wirings, a sealing material 2b, and a back surface protective film 4.
Is. Molded body 10 integrated by these members
Is formed. At this time, the solar battery cells 3 are placed at intervals, and the solar battery cells 3 are sandwiched between the sealing materials 2a and 2b from above and below.

The mounting base 8 has an open lower surface, and a boundary sheet 11 made of rubber or the like having heat resistance is sandwiched between the upper layer 12 and the upper layer 12.
And the lower layer 13 is divided into two layers. The mounting base 8 is openably and closably supported on the mounting base 6 by an opening / closing member 14 such as a cylinder, and when closed, adheres to the seal material 15 of the mounting base 6 to completely seal the lower layer 13. Then, the upper layer 12 and the lower layer 13 are evacuated or filled with air to pressurize the molded body 10 to perform lamination.

The frame 7 is, as shown in FIG.
It has a shape surrounding the periphery of 0 and has an opening 16 larger than the region in which the solar battery cells 3 are arranged. That is, when the molded body 10 is pressed into contact with the solar cell 3
If it overlaps, the solar cell 3 may be damaged by the pressure. Therefore, the width of each piece of the frame body 7 is determined by the molded body 10
It is set to be slightly smaller than the distance from the peripheral edge to the solar battery cell 3. Alternatively, the width of one piece of the frame body 7 may be increased so that the solar battery cells 3 are arranged near the center of the molding target 10. Furthermore, the transparent substrate 1 and the back surface protective film 4
Alternatively, the dimensions of the frame body 7 may be matched with those dimensions, and the width of one piece of the frame body 7 may be increased accordingly. The larger the value, the lower the water vapor permeability.

Further, the height of the frame body 7 is set so that the pressure from the upper layer 12 is uniformly applied to the molded body 10 in the lower layer 13 during lamination.

As shown in FIG. 5, the frame 7 is made of a heat-resistant composite material that is not deformed or deteriorated even at the time of lamination. For example, an elastic body 21 such as isoprene rubber and aluminum are used. Of the metal member 22. The elastic body 21 and the metal member 22 are fixed to each other with an adhesive 23. Since the elastic body 21 of the frame body 7 is in direct pressure contact with the surface of the back surface protection film 4, the back surface protection film 4 is not damaged. Further, since the high temperature strength is secured by the metal member 22, the frame body 7 is not deformed or deteriorated even when laminated, and can be used for a long period of time.

As a modified example of the frame body 7, as shown in FIG. 6, an adhesive 23 is applied to a part of the upper surface and the side surface of the elastic body 21, and the metal member 22 is fixed so as to surround the periphery. The ones that have been made are listed. Thereby, the elastic body 21
The bonding area between the metal member 22 and the metal member 22 is increased, and the bonding strength is further improved. Further, as shown in FIG. 7, a metal member 22 covered with an elastic body 21 may be used.

On the base end side of the metal member 22 of the frame body 7, as shown in FIG.
As shown in FIG. 2, two rod-shaped support pieces 24 are provided, and a cylindrical support portion 25 is formed at the tip of the support piece 24. Further, two support pieces 26 are also provided so as to project from the inner wall on the side of the mounting base 8, and the cylindrical support portion 2 is provided at the tip thereof.
7 is provided. A round bar 28 is inserted into the holes of these supporting portions 25 and 27, and the frame 7 is rotatably supported by the round bar 28.

On the other end side of the metal member 22 of the frame body 7, a mounting locking portion 31 for mounting the frame body 7 on the mounting base 8.
Is provided. This comprises a hook 33 attached to the tips of a pair of chains 32 connected to the metal member 22, and a stainless steel eyebolt 34 attached to the inner wall of the attachment base 8.

When the frame 7 is mounted on the mount 8, the hook 33 may be hooked in the hole of the eyebolt 34. Further, the hook 33 is removed from the eyebolt 34, and the round bar 2
By pulling out the frame 8, the frame 7 can be freely attached to and detached from the mount 8. Therefore, it is possible to easily change to another frame body having a different size corresponding to the solar cell modules of various sizes. The frame 7 may be formed integrally with the mount 8.

In this embodiment, when the molded body 10 is pressure-molded by laminating, the frame 7 is attached to the mounting base 8 and the peripheral edge of the surface of the molded body 10 is pressed by the frame 7. As a result, the back surface protective film 4 is pressure-bonded to the translucent substrate 1 via the sealing material 2, and the thickness of the peripheral portion of the sealing material 2 is made thinner than the thickness of the central portion thereof, as shown in FIG. Therefore, invasion of water vapor from the peripheral portion of the molded body 10 can be further prevented as compared with the conventional laminating method, and the sealing effect can be significantly improved.

Further, since the frame body 7 is attached to the mounting base 8, it is possible to save the trouble of setting the frame body 7 to the molded object 10 placed on the frame body 7 one by one. Also, the molded body 10
When mounting on the sample table 9, it may be mounted according to the mounting position of the frame body 7 fixed to the mounting table 8. for that reason,
Positioning of the molded body 10 on the sample table 9 is also facilitated, the preparatory work for lamination can be easily performed, and the working time can be shortened.

Further, since the mounting base 8 can be opened and closed with respect to the mounting base 6 with the frame body 7 attached, after laminating,
When taking out the solar cell module from the laminating apparatus 5, for example, it is not necessary to manually lift the frame body 7,
There are advantages that the solar cell module can be easily attached and detached, labor can be reduced, and workability is improved.

Here, when the conventional lamination is performed, the sealing material 2 may protrude from the molded body 10.
Therefore, in order to prevent the sealing material 2 from protruding, the dimensions and thickness of the sealing material 2 are set before the sealing material 2 is set in advance. In addition, the dimension here means the vertical width and the horizontal width of the sealing material 2.

The thickness of the peripheral edge of the encapsulating material 2 after lamination is determined by the amount of the encapsulating material 2 at the position where the frame body 7 before lamination is in pressure contact, and the encapsulating material depending on the heating temperature and pressure during lamination. 2 and the flow characteristics in the outward direction.

With these, the amount of the sealing material 2 protruding from the molded body 10 after lamination can be grasped in advance. In other words, the sealing material 2 is prevented from protruding from the molded body 10. The amount of 2 can be preset. Then, the size and thickness of the sealing material 2 are adjusted in advance according to the set amount. Specifically, for example, the thickness of the sealing material 2 is set to 60.
Set the size of the sealing material 2 to 0 μm, and set the size of the sealing material (upper side) 2b.
Is set to be 10 mm smaller than the transparent substrate 1, and the sealing material (lower side) 2a is set to be 1.5 mm smaller than the transparent substrate 1.

As described above, it is more desirable to make the sealing material (upper side) 2b smaller and the sealing material (lower side) 2a larger. That is, the encapsulating material (upper side) 2b is used to cover the solar battery cells 3, and the encapsulating material (lower side) 2a is used to closely adhere to and seal the back surface protective film 4. If this is done, the upper side tends to flow due to gravity, and there is a risk of it protruding.

By thus setting the size and thickness of the sealing material 2, the thickness of the peripheral edge portion of the sealing material 2 can be made thinner than the pressure applied by the conventional laminating method. It is possible to prevent the sealing material 2 from protruding outside the translucent substrate 1. Therefore, it is possible to omit the step of cutting the extra sealing material 2 protruding to the outside of the translucent substrate 1 after lamination as in the conventional case. In addition, it is possible to eliminate waste of unnecessary members for cutting. Therefore, the manufacturing process can be simplified, the manufacturing time can be shortened, and the cost of parts can be reduced.

The size of the back surface protection film 4 is set to the same size as the transparent substrate 1 before being set. By doing so, the back surface protective film 4 can be prevented from protruding to the outside of the molded body 10. Therefore, similar to the encapsulating material 2, it is possible to omit the step of cutting the extra back surface protection film 4 that has been extruded after the lamination.

Further, conventionally, the back surface protective film 4 may be displaced due to pressure during lamination. However, in the present embodiment, by pressing the peripheral edge of the back surface protection film 4 with the frame body 7, it is possible to eliminate the positional deviation of the back surface protection film 4 that occurs during lamination.

Next, a manufacturing procedure for manufacturing the solar cell module will be described. First, the frame 7 is attached to the mount 8.
Mount the solar cell module components on the mounting table 6
Place on. As shown in FIG. 1, the mounting order is the transparent substrate 1, the sealing material (lower side) 2a, the solar cell 3, the sealing material (upper side) 2b, and the back surface protective film 4. The encapsulating material (lower side) 2a and the encapsulating material (upper side) 2b are integrated by heating and pressurizing, and after laminating, one encapsulation that encloses the solar battery cell 3 It becomes material 2.

After the molded body 10 is set, the mounting base 8 is closed to bring the mounting base 6 and the mounting base 8 into contact with each other.
At this time, the frame body 7 contacts the peripheral edge portion of the molding target 10, that is, the peripheral edge portion of the back surface protection film 4 (see FIG. 1). However, the solar battery cell 3 is not damaged by the frame of the frame body 7.

Next, after the inside of the mounting base 8 is completely sealed, the upper layer 12 and the lower layer 13 inside the mounting base 8 are degassed to a vacuum state and heated. After a lapse of a predetermined time, air is enclosed only in the upper layer 12 and the lower layer 13 is kept in a vacuum state. As a result, the boundary sheet 11 becomes the lower layer 13
It is elastically deformed to the side, and a uniform pressure of about 1 atm is applied in the lower layer 13 to perform pressing. The encapsulating material 2 flows by heat and pressure, wraps the solar battery cells 3 and also enters between the translucent substrate 1 and the back surface protective film 4, and the encapsulating material 2, the translucent substrate 1 and the sun The battery cells 3 come into close contact with each other.

At this time, the sealing material 2 below the frame 7
Is pressed down and tries to flow out. However, since the amount of the sealing material 2 in this portion is small and the sealing material 2b is smaller than the sealing material 2a and the transparent substrate 1, it only reaches the outer edge of the peripheral edge and does not protrude to the outside. , Thinly formed.

Further, the sealing material 2 on the inner side of the frame tries to flow out to the outer side, but cannot move because the frame body 7 becomes an obstacle, and as shown in FIG. 2, the opening 16 of the frame body 7 is opened. A bulge of the sealing material 2 occurs in the portion, and the sealing material 2 is formed thick.

Before the lamination is completed, the upper layer 12 is evacuated and the lower layer 13 is filled with air. This allows
The lower layer 13 becomes equal to atmospheric pressure. Then, the mounting base 8 is opened, the molding target 10 is taken out from the laminating apparatus 5, and the sealing material 2 is dried with an oven or the like to improve the adhesiveness of the sealing material 2.
Cross-link. Then, the peripheral edge portion of the molded body 10 is wrapped with a seal member, and a protective frame frame made of aluminum or the like is attached to complete the solar cell module.

The thickness of the peripheral portion of the solar cell module is
A predetermined value, for example, 100 μm or less is obtained by laminating while being pressed against the frame body 7. As described above, the thinner the peripheral portion, the narrower the passage through which water vapor permeates, and the greater the sealing effect. Therefore, even if an inexpensive sealing member is used, the invasion of water vapor can be prevented and the cost can be reduced. If the thickness of the peripheral portion is thin, a compact solar cell module can be manufactured even if the seal member is wound. Therefore, a so-called building material-integrated solar cell module integrally formed with a roof tile or a building wall can be easily manufactured, and a solar cell module with a good appearance that can be easily installed in a house, a building, or the like can be provided.

[0049]

EXAMPLES Next, examples of the method for manufacturing a solar cell module of the present invention will be described. First, two sheet-shaped encapsulating materials made of EVA resin were placed on a translucent substrate of 120 mm square with a solar cell interposed therebetween. The sealing material has a thickness of 600 μm, and the dimension is to be mounted on the upper surface of the translucent substrate. The sealing material is 1.5 mm shorter than the end, and is mounted on the upper surface of the solar cell. The sealing material used was shortened by 10 mm from the end. A back surface protective film having a structure in which aluminum was sandwiched between black PET was placed thereon and laminated.

As a comparative example, a solar cell module was manufactured by the conventional manufacturing method. After that, both were laminated with a sealing material such as butyl rubber, and the thickness of the EVA resin after lamination was measured with a micrometer. In addition, a humidity resistance test (85 ° C., 90% RH) was performed, and the degree of clouding of the EVA resin due to water vapor permeation into the sample was visually observed. Table 1 shows the measured values of the EVA resin thickness and the results of visual observation.

[0051]

[Table 1]

According to Table 1, the conventional one has 8
While the thickness was 00 μm, in the example, the thickness of the peripheral portion of the sealing material after lamination could be 100 μm or less from the edge to the vicinity of 10 mm.

Further, as a result of a moisture resistance test, in the conventional example, after 1,000 hours (JIS condition), turbidity had progressed to the central portion of the sample, whereas in the sample of the example, the cloudiness was 1,000. There was no change in appearance even after hours. That is, it was found that this example in which the thickness of the EVA resin on the peripheral portion of the solar cell module was thinned greatly improved the moisture resistance.

The coupon size (vertical width 300 mm ×
The same tendency was obtained for the thickness of the sealing material also in the translucent substrate having a width of 150 mm.

The present invention is not limited to the above embodiment, and many modifications and changes can be made to the above embodiment within the scope of the present invention.

[0056]

As described above, according to the present invention, the protective material is pressure-bonded to the translucent material through the sealing material by laminating the peripheral edge of the molding target with the frame. In addition, since the thickness of the peripheral portion of the sealing material can be made thinner than the thickness of the central portion, it is possible to prevent the infiltration of water vapor into the inside of the molding target, and the sealing performance is significantly improved. Therefore, it is possible to prevent deterioration of the constituent members including the solar battery cell, and it is possible to provide a highly reliable solar battery module having excellent weather resistance.

Further, for example, even if an inexpensive sealing material is used to protect the end surface of the solar cell module, it is possible to prevent the invasion of water vapor, so that the cost can be reduced.
Also, if the thickness of the peripheral portion is thin, a compact solar cell module can be produced even by winding a sealing member, and a so-called building material integrated solar cell module that is integrally formed with roof tiles, building walls, etc. The solar cell module can be easily manufactured, and can be easily installed in a house, a building, or the like and has a good appearance.

If the size of the sealing material before lamination is made smaller than that of the light-transmitting material and the protective material, or if the size of the protective material is the same as that of the light-transmitting material, the sealing material will be covered by the laminate. Since it does not stick out to the outside of the molded body, it is possible to eliminate the conventional cutting step. Therefore, the manufacturing process can be simplified and the manufacturing time can be shortened.

Further, by moving the mounting table to which the frame is attached relative to the mounting table, the work for aligning the frame and the molded body can be easily performed, and the labor required for this work is reduced. Disappear. Moreover, since it is not necessary to directly handle the frame body before and after the laminating work, the work of taking out the solar cell module becomes easy, the workability is improved, and the mass productivity is improved.
