Description

  The present invention relates to a method for manufacturing a solar cell module including a solar cell in which a first polarity electrode and a second polarity electrode are formed on the back surface, and a wiring substrate to which the solar cell is connected, and such a solar cell. The present invention relates to a temporary fixing jig set applied to a battery module manufacturing method.

  With the technological development of solar power generation, various improvements have been made to the structure of solar cells. In recent years, both the first polarity (for example, p-type) electrode and the second polarity (n-type) electrode are formed on the back surface (the surface opposite to the light receiving surface) of the silicon substrate, and the wiring pattern of the wiring substrate is formed. A back electrode type solar cell in which both back electrodes are aligned and connected has been proposed (for example, see Patent Document 1).

  However, since the electrode formed on the back surface of the solar battery cell is connected to the wiring pattern, there is a problem that the alignment is not easy. As a solution, it is conceivable to form an alignment mark on the surface of the solar battery cell, but the surface is a light receiving surface, which is not a sufficient solution because the light receiving surface is sacrificed.

  Moreover, the back surface pattern observation method of a back electrode type photovoltaic cell is also proposed (for example, refer patent document 2). However, there is a problem that the apparatus becomes large and a burden is generated in terms of workability.

  That is, the manufacturing method of the solar cell module 1 (see FIG. 3E) according to the present embodiment is a position mark with respect to the electrode (the first electrode 41p or the second electrode 41n) disposed on the outermost side of the solar cell 40. Therefore, the solar battery cell 40 can be positioned extremely easily and with high accuracy with respect to the cell temporary fixing jig 30. Since alignment is made with respect to the wiring pattern 22 formed on the wiring substrate 20 with the back surface 45 of the solar cell 40 facing the front surface, the solar cell 40 does not need to be provided with an alignment mark and is formed as a specification. Since the electrode pattern 41 can be used as it is, extremely effective positioning can be performed.

  In FIG. 2A, the plan area | region where the photovoltaic cell 40 is arrange | positioned is shown with a dashed-two dotted line as the cell area | region SB. In the present embodiment, four cell regions SB are formed in parallel so that four solar cells 40 are arranged.

  The position mark (cell positioning portion 36) is added (marked) to the cell temporary fixing jig 30 in advance so as to face the electrode patterns 41 (see FIGS. 2C and 2D) arranged at both ends of the solar battery cell 40. . Since the outermost electrode pattern 41 of the solar battery cell 40 is used for positioning with respect to the position mark (cell positioning part 36), the solar battery cell 40 can be easily and highly accurately attached to the cell temporary fixing jig 30. Can be aligned. The position mark can be formed on the cell temporary fixing jig 30 by appropriate ruled writing, printing (coloring) or the like.

  The cell temporary fixing part 31 (second groove) is connected to the second vacuuming device 38 via the vacuum path 32 and is configured to temporarily fix the solar battery cell 40 to the cell temporary fixing jig 30 by the suction force Vc. ing. As the second vacuuming device 38, for example, a vacuum pump can be applied.

  The cell temporary fixing portion 31 (second groove) is formed in a region where the solar battery cell 40 is disposed, and is formed so that an even temporary fixing force (for example, adsorption force) is applied to the solar battery cell 40. . As with the substrate temporary fixing jig 10, the cell temporary fixing jig 30 is preferably a light metal with little deformation and easy to process, and is formed of, for example, an aluminum plate having a thickness of about 5 mm.

  The cell temporary fixing jig 30 (second base 30s) includes a concave portion 34 into which the substrate positioning portion 11 (projection) is inserted. The cell temporary fixing jig 30 is positioned in a self-aligned manner with respect to the substrate temporary fixing jig 10 by the recess 34.

  FIG. 2C is a plan view showing a state in which solar cell 40 is positioned and temporarily fixed to cell temporary fixing jig 30 in the method for manufacturing solar cell module 1 according to Embodiment 1 of the present invention.

  FIG. 2D is a side view showing a side surface state in the direction of the arrow 2D in FIG. 2C.

  The solar battery cell 40 includes a cell substrate 40s formed of, for example, polycrystalline silicon or single crystal silicon. Each surface of the cell substrate 40 s constitutes a light receiving surface 44 and a back surface 45 opposite to the light receiving surface 44. The solar cell 40 includes a first electrode 41p having a first polarity and a second electrode 41n having a second polarity formed on the back surface 45. That is, the solar cell 40 includes the first electrode 41p and the second electrode 41n arranged alternately in parallel via the space 41s on the back surface 45 as the electrode pattern 41.

  The first electrode 41p and the second electrode 41n are joined to an appropriate impurity region through a window portion opened in an insulating film (passivation film formed of silicon oxide, silicon nitride, or the like) formed on the back surface 45 ( The internal structure itself of the solar battery cell 40 is not shown because it is not related to the gist of the present invention, and acts as a terminal of the first polarity (for example, p-type) and the second polarity (for example, n-type), respectively. . The first electrode 41p and the second electrode 41n are made of a metal such as silver, for example.

  The solar cell 40 only needs to have an electrode pattern 41 corresponding to two polarities (p-type as the first polarity and n-type as the second polarity) formed on the back surface 45, and other structures (for example, the back surface 45). The insulating film formed on the surface, the photoelectric conversion region formed on the surface 44 side, the antireflection film, etc.) can be applied to any solar cell having any structure.

  The solar battery cell 40 is positioned on the cell temporary fixing jig 30 via the cell positioning part 36 (position mark). Next, when the second evacuation device 38 is operated, the solar cell 40 is evacuated to the second base 30s side via the cell temporary fixing portion 31 (second groove). Accordingly, the solar battery cell 40 is temporarily fixed and fixed to the cell temporary fixing jig 30 (second base 30s) via the cell temporary fixing portion 31 (second groove).

  That is, in FIG. 2C and FIG. 2D, the solar cell is attached to the cell temporary fixing jig 30 having the cell positioning part 36 (position mark) for positioning the solar battery cell 40 and the cell temporary fixing part 31 for temporarily fixing the solar battery cell 40. A step of positioning and temporarily fixing the cell 40 is shown.

  In the present embodiment, the cell substrate 40s is formed of a silicon substrate (single crystal silicon substrate, polycrystalline silicon substrate) having a thickness of, for example, about 100 μm to 500 μm. The electrode pattern 41 (silver electrode) has a film thickness of, for example, about 5 μm to several tens of μm.

  Specifically, the thickness of the cell substrate 40s (silicon substrate) is, for example, about 200 μm, and the thickness of the electrode pattern 41 (silver electrode) is about 20 μm. The planar shape of the cell substrate 40s is about 100 mm in the length direction and about 25 mm in the width direction, for example.

  FIG. 3A is a schematic diagram schematically showing a part of the process of positioning the cell temporary fixing jig 30 with respect to the temporary substrate fixing jig 10 in the method for manufacturing the solar cell module 1 according to Embodiment 1 of the present invention. It is a top view.

  In contrast to the temporary substrate fixing jig 10 (substrate positioning portion 11) for temporarily fixing the wiring substrate 20, the temporary substrate fixing jig 30 (concave portion 34) for temporarily fixing the solar cells 40 is connected to the substrate positioning portion 11. Then, positioning and alignment are performed via the recess 34. That is, the concave portion 34 (cell temporary fixing jig 30, solar battery cell 40) is moved in the direction of the arrow 3A so as to face the substrate positioning portion 11, and the substrate positioning portion 11 (pin as a projection. Substrate temporary fixing). Position and align with jig 10 and wiring board 20).

  Note that the movement relationship between the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 is relative, and in FIG. 3A, the cell temporary fixing jig 30 (recess 34) is formed in the direction indicated by the arrow 3A. ) Is positioned on the substrate temporary fixing jig 10 (substrate positioning portion 11), and the alignment is performed. However, conversely, the substrate temporary fixing jig 10 (substrate positioning portion 11) may be positioned and aligned with respect to the cell temporary fixing jig 30 (concave portion 34).

  FIG. 3B shows a positioning state after the cell temporary fixing jig 30 is moved with respect to the substrate temporary fixing jig 10 shown in FIG. 3A.

  FIG. 3B is a side view showing the positional relationship among the temporary substrate fixing jig 10, the wiring substrate 20, the cell temporary fixing jig 30, and the solar battery cell 40 in the side surface state after the step shown in FIG. 3A.

  FIG. 3B shows a state in which the solar battery cell 40 (cell temporary fixing jig 30) is positioned with respect to the wiring board 20 (substrate temporary fixing jig 10). After positioning, the solar cell 40 is adhered to the wiring board 20 by moving the cell temporary fixing jig 30 (solar cell 40) in the direction of the arrow 3B (see FIG. 3C).

  In the state where the positioning hole 24 (wiring substrate 20) and the recess 34 (cell temporary fixing jig 30) are positioned via the substrate positioning portion 11, the adhesive 26 disposed on the surface of the wiring substrate 20 is still in the solar cell. It is not adhered to 40. In the state where the positioning hole 24 and the recess 34 are positioned via the substrate positioning portion 11, the electrode pattern 41 (first electrode 41p, second electrode) with respect to the wiring pattern 22 (first wiring 22p, second wiring 22n). 41n) is positioned (aligned) with high accuracy.

  The moving direction of the cell temporary fixing jig 30 with respect to the temporary substrate fixing jig 10 indicated by an arrow 3B is relative to the substrate temporary fixing jig 30 in a direction opposite to the arrow 3B. The temporary fixing jig 10 may be moved.

  As shown in FIGS. 1A to 3B, in the method for manufacturing solar cell module 1 according to the present embodiment, wiring substrate 20 includes positioning holes 24 through which protrusions (substrate positioning portions 11) pass, and temporarily fixes cells. The jig 30 includes a recess 34 into which a protrusion (substrate positioning portion 11) is inserted. In the step of positioning and temporarily fixing the wiring board 20 to the temporary substrate fixing jig 10 (FIGS. 1E and 1F), A process of inserting a protrusion into the positioning hole 24, aligning the substrate temporary fixing jig 10 and the cell temporary fixing jig 30, and aligning the wiring substrate 20 and the solar battery cell 40 with each other (FIGS. 3A and 3B). Then, it is preferable that the protrusion (substrate positioning part 11) penetrating the positioning hole 24 is inserted into the recess 34.

  Therefore, the method for manufacturing the solar cell module 1 is formed on the protrusion (substrate positioning portion 11) formed on the temporary substrate fixing jig 10, the positioning hole 24 formed on the wiring substrate 20, and the temporary cell fixing jig 30. Therefore, the solar cell 40 (the first electrode 41p and the second electrode 41n) and the wiring substrate 20 (the first electrode 41n) can be easily and highly accurately positioned. The wiring 22p and the second wiring 22n) can be aligned.

  FIG. 3C is a side view in which the solar cell 40 is bonded to the wiring substrate 20 by bringing the temporary substrate fixing jig 10 and the temporary cell fixing jig 30 close to each other after the positioning step shown in FIG. FIG.

  The solar battery cell 40 is bonded to the adhesive 26 disposed (formed) on the surface of the wiring board 20. In the step shown in FIG. 3C, the solar cells 40 are temporarily bonded to the adhesive 26 (temporary bonding state), and the bonding between the wiring board 20 and the solar cells 40 is in a temporary state. The wiring pattern 22 and the electrode pattern 41 are not yet bonded (connected). That is, the adhesive 26 is in a softened state that allows temporary bonding.

  In other words, the temporary adhesion means that the solar battery cell 40 is pressed against the adhesive 26 disposed on the surface of the wiring board 20 and fixed to such an extent that the solar cell 40 is not misaligned by the adhesiveness (adhesiveness) of the adhesive surface. (The same applies to the following).

  In the present embodiment, before bonding the wiring substrate 20 and the solar battery cell 40 (temporary bonding), the wiring substrate 20 is temporarily fixed by the temporary substrate fixing jig 10, and the solar battery cell 40 is temporarily fixed by the cell fixing jig. 30, but after bonding (temporary bonding) the wiring substrate 20 and the solar battery cell 40, the first vacuuming device 18 and the second vacuuming device 38 are respectively connected to the substrate temporary fixing jig 10 and The temporary fixing can be ended (released) by releasing from the cell temporary fixing jig 30.

  That is, in the step shown in FIG. 3C, the wiring board 20 and the solar battery cell 40 are temporarily bonded to each other in a state where the wiring board 20 and the solar battery cell 40 are aligned with each other. The temporary fixing with respect to the wiring substrate 20 and the solar battery cell 40 is released while the cell temporary fixing jig 30 is aligned. In the case of FIG. 3C, the action of the first vacuuming device 18 and the second vacuuming device 38 on the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 is released. Specifically, the first vacuuming device 18 and the second vacuuming device 38 can be removed.

  Note that the temporary fixing force (adsorption force / suction force) by the temporary substrate fixing jig 10 and the temporary cell fixing jig 30 is applied pressure in the following heating and pressurizing steps (see the heating and pressurizing process HP in FIG. 3D). )), The degree of the temporary fixing force is not limited to releasing the temporary fixing force, but the temporary fixing force is maintained as it is or the temporary fixing force is reduced. It is possible to cope with various problems such as maintaining the Therefore, in the present embodiment, temporary fixing can be adjusted as appropriate in the following steps.

  3D, after the bonding (temporary bonding) step shown in FIG. 3C, the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 are heated and pressurized, and the wiring substrate 20 is solar cell. It is a side view which shows the side surface state to which the cell 40 was adhere | attached.

  The wiring substrate 20 (substrate temporary fixing jig 10) and the solar battery cell 40 (wiring substrate 20) in the temporarily bonded state shown in FIG. 3C are carried into the heating / pressurizing device 50 and subjected to the heating / pressurizing treatment HP. Heating and pressurization are performed in the direction of the arrow of the heat and pressure treatment HP. The heating and pressurizing process HP for the temporary substrate fixing jig 10 and the temporary cell fixing jig 30 results in a heating process and a pressurizing process for the wiring board 20 and the solar battery cell 40, and the wiring board 20 and the solar battery cell. 40 is securely bonded via the adhesive 26. As the heating and pressing apparatus 50, for example, a hot press machine (vacuum laminator) or the like can be applied.

  That is, in the step shown in FIG. 3D, after temporarily bonding the wiring substrate 20 and the solar battery cell 40 to each other, the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 are heated and pressurized, The wiring board 20 and the solar battery cell 40 are bonded to each other.

  In the present embodiment, since the adhesive 26 that bonds the wiring substrate 20 and the solar battery cell 40 is an anisotropic conductive adhesive, the wiring pattern 22 of the wiring board 20 and the solar battery cell 40 It is not necessary to directly adhere to the electrode pattern 41. The state of the adhesive 26 (anisotropic conductive adhesive) between the wiring pattern 22 and the electrode pattern 41 will be further described with reference to FIG. 3F.

  The adhesive 26 first connects the wiring pattern 22 and the electrode pattern 41 in the softened state by heat treatment and pressure treatment under a preset condition in the heat and pressure apparatus 50 (see FIG. 3F). The pressurization state at this time may be as long as connection (ensurement of conductivity) is established between the wiring pattern 22 and the electrode pattern 41. Further, by continuing the heating (or finishing the heating state depending on the type of the adhesive), the adhesive 26 is cured to be resin-sealed between the wiring board 20 and the solar battery cell 40. Then, the wiring substrate 20 (wiring pattern 22) and the solar battery cell 40 (electrode pattern 41) are bonded (connected) to each other. Further, the connection of the wiring pattern 22 and the electrode pattern 41 is strengthened by the curing of the adhesive 26, and the reliability can be ensured.

  That is, in the step of bonding the wiring substrate 20 and the solar battery cell 40 to each other (step of FIG. 3D), the first electrode 41p is connected to the first wiring 22p, and the second electrode 41n is connected to the second wiring 22n. . Therefore, the solar cell module 1 according to the present embodiment can output the generated power generated by the photoelectric conversion of the solar cells 40 from the wiring board 20.

  FIG. 3E is a side view showing a side state of the solar cell module 1 in a completed state in which the wiring substrate 20 and the solar cells 40 are connected to each other by the heating and pressing treatment HP step shown in FIG. 3D.

  The substrate temporary fixing jig 10 and the cell temporary fixing jig 30 are taken out from the heating and pressing device 50, and the wiring board 20 and the solar battery cell 40 are taken out from the substrate temporary fixing jig 10 and the cell temporary fixing jig 30. That is, the solar cell module 1 in a state where the wiring substrate 20 and the solar cells 40 are bonded by the process shown in FIG. 3D is obtained.

  In the solar cell module 1, the light receiving surface 44 of the solar cell 40 is disposed on the front surface side, and the wiring substrate 20 is disposed on the back surface 45 side of the solar cell 40. Therefore, since the solar cell module 1 outputs the photovoltaic power generated by the solar cells 40 from the back surface 45 side (the wiring board 20 disposed on the back surface 45), the area of the light receiving surface 44 is effectively utilized. High power generation efficiency can be realized.

  3F is an enlarged schematic view schematically showing an enlarged connection state of the wiring pattern 22 and the electrode pattern 41 of the solar cell module 1 shown in FIG. 3E.

  Since the adhesive 26 is an anisotropic conductive adhesive, the resin contains conductive particles 26c (conductive particles 26cc) having a particle size of, for example, about several μm to several tens of μm. The conductive particles 26 c (conductive particles 26 cc) are made of a metal such as silver, for example, and are distributed substantially uniformly in the adhesive 26. Therefore, a region sandwiched between the wiring pattern 22 (thickness 35 μm) and the electrode pattern 41 (thickness 20 μm) (a region where the first wiring 22p and the first electrode 41p face each other, a second wiring 22n and a second wiring The conductive particles 26 cc distributed in the region facing the electrode 41 n are distributed in a narrower region than the conductive particles 26 c distributed in other regions.

  That is, the conductive particles 26c distributed in other regions (space 22s, space 41s) that do not face the first wiring 22p, the second wiring 22n, the first electrode 41p, and the second electrode 41n are separated from the insulating substrate 20s (flexible). Film) and the cell substrate 40s are distributed separately from each other, and insulation between the insulating substrate 20s (flexible film) and the cell substrate 40s is ensured. On the other hand, the conductive particles 26cc sandwiched between the first wiring 22p, the second wiring 22n, the first electrode 41p, and the second electrode 41n are brought into contact with each other so that the conductive particles 26cc come into contact with each other. Therefore, conductivity is generated by the adhesive 26 (conductive particles 26 cc) between the first wiring 22p and the first electrode 41p, and between the second wiring 22n and the second electrode 41n, and the first wiring 22p and the first electrode 41p. The electrode 41p is connected, and the second wiring 22n and the second electrode 41n are connected.

  The conductive particles 26 cc have a thickness of 35 μm between the first wiring 22 p and the second wiring 22 n and the first electrode 41 p and the second electrode 41 n from the distance between the insulating substrate 20 s (flexible film) and the cell substrate 40 s. It is sandwiched between narrow regions with an interval (about 55 μm) corresponding to the sum of the thickness of 20 μm. For example, when the distance between the insulating substrate 20s (flexible film) and the cell substrate 40s is about 90 μm, the conductive particles 26cc are arranged in a region of about 35 μm (90 μm−55 μm = 35 μm), Contact each other. Between the first wiring 22p and the first electrode 41p and between the second wiring 22n and the second electrode 41n, a conductive path (conductive path) is formed by the conductive particles 26cc.

  Therefore, the wiring board 20 (wiring pattern 22) and the solar battery cell 40 (electrode pattern 41) are bonded (connected) to each other, and the solar battery module 1 is formed.

  As described above, in the method for manufacturing the solar cell module 1 according to the present embodiment, the adhesive 26 is an anisotropic conductive adhesive, and the connection between the first electrode 41p and the first wiring 22p and the second electrode 41n. And the second wiring 22n are connected via an anisotropic conductive adhesive.

  Therefore, in the method for manufacturing solar cell module 1 according to the present embodiment, connection between first electrode 41p and first wire 22p and connection between second electrode 41n and second wire 22n are connected to wiring substrate 20 and the solar cell. 40 is performed via an anisotropic conductive adhesive disposed between the wiring substrate 20 and the wiring substrate 20 with the anisotropic conductive adhesive previously formed in a region corresponding to the solar battery cell 40 of the wiring substrate 20. Since it can be temporarily fixed to the substrate temporary fixing jig 10, the wiring substrate 20 and the solar battery cell 40 can be bonded easily and with high accuracy by a simple process. Since the anisotropic conductive adhesive acting as a sealing agent is filled between the battery cells 40, the reliability can be improved.

  In the method for manufacturing solar cell module 1 according to the present embodiment, the process of each step is performed in a state where an anisotropic conductive adhesive (adhesive 26) is formed in advance in a region corresponding to solar cell 40 of wiring substrate 20. In the process of adhering the wiring substrate 20 and the solar battery cell 40 to each other, the first wiring 22p and the first electrode 41p are connected by heating and pressing, and the second wiring 22n and the second electrode 41n are connected together. In addition, resin sealing (resin sealing with a non-conductive adhesive) is performed between the wiring substrate 20 and the solar battery cell 40.

  The anisotropic conductive adhesive (adhesive 26) is applied to the surface of the wiring board 20 before temporarily fixing the wiring board 20 to the temporary board fixing jig 10, and is initially uncured in the subsequent steps. An epoxy resin, which is a synthetic resin having a property of being cured after being softened by heat and pressure treatment, is applied. The heating and pressurizing process conditions (particularly temperature, time, and pressurizing conditions) are appropriately adjusted according to the properties and characteristics of the adhesive 26 to be applied.

  As described above with reference to FIGS. 1A to 3F, the method for manufacturing the solar cell module 1 according to the present embodiment includes the first electrode 41 p having the first polarity on the back surface 45 opposite to the light receiving surface 44. The solar cell 40 in which the second electrode 41n of the second polarity is formed, the first wiring 22p connected to the first electrode 41p, and the second wiring 22n connected to the second electrode 41n are the surface of the insulating substrate 20s. It is a manufacturing method of the solar cell module 1 provided with the wiring board 20 formed in this.

  Moreover, the manufacturing method of the solar cell module 1 according to the present embodiment includes a substrate having a substrate positioning portion 11 for positioning the wiring substrate 20 and a substrate temporary fixing portion 13 (for example, a first groove) for temporarily fixing the wiring substrate 20.

A step (FIGS. 2A to 2D) of positioning and temporarily fixing the solar battery cell 40 to the cell temporary fixing jig 30 having the cell temporary fixing portion 31 (for example, the second groove), and temporarily fixing the wiring substrate 20 The step of aligning the wiring substrate 20 and the solar cell 40 with each other by aligning the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 temporarily fixing the solar cell 40 (FIG. 3A) Beauty and Figure 3B), characterized in that it comprises a step of bonding the wiring board 20 and the solar cell 40 are aligned with each other (FIG. 3C and FIG 3E).

  Therefore, the method for manufacturing the solar cell module 1 according to the present embodiment includes the substrate temporary fixing jig 10 in which the wiring substrate 20 is positioned and temporarily fixed, and the cell temporary fixing jig in which the solar cell 40 is positioned and temporarily fixed. Since the wiring board 20 and the solar battery cell 40 are aligned by aligning 30 with the wiring board 20, the wiring board 20 and the solar battery cell 40 are not provided with alignment marks for the solar battery cell 40 and the wiring board 20. Can be bonded, and the solar cell module 1 constituted by the wiring substrate 20 and the solar cell 40 can be easily and accurately manufactured.

  Moreover, in the manufacturing method of the solar cell module 1 according to the present embodiment, the step of bonding the wiring substrate 20 and the solar cell 40 to each other (FIGS. 3C to 3E) is performed by bonding disposed on the surface of the wiring substrate 20. It is preferably performed via the agent 26.

  Therefore, the method for manufacturing the solar cell module 1 according to the present embodiment makes it possible to reliably bond the wiring substrate 20 and the solar cell 40, and to manufacture the highly reliable solar cell module 1. .

  Further, in the method for manufacturing solar cell module 1 according to the present embodiment, in the step of bonding wiring substrate 20 and solar cell 40 to each other (FIGS. 3C and 3D), wiring substrate 20 and solar cell 40 are mutually connected. It is preferable that the wiring substrate 20 and the solar battery cell 40 are temporarily bonded to each other in a state of being aligned with each other, and then the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 are heated and pressurized.

  Therefore, the manufacturing method of the solar cell module 1 according to the present embodiment is in a state in which the substrate temporary fixing jig 10 that positions the wiring substrate 20 and the cell temporary fixing jig 30 that positions the solar cells 40 are aligned. After the wiring substrate 20 and the solar battery cell 40 are temporarily bonded to each other, the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 are heated and pressurized. The process after alignment can be simplified to improve workability.

That is, blowing AVc such as air is applied to the solar cell 40 through the vacuum path 32 and the cell temporary fixing portion 31.

  In the present embodiment, after temporary bonding (FIG. 3C), the temporary fixing to the solar battery cell 40 by the temporary cell fixing jig 30 is released to separate the solar battery cell 40 from the temporary cell fixing jig 30. Thereafter, the temporary fixing by the substrate temporary fixing jig 10 to the wiring substrate 20 to which the solar cells 40 are temporarily bonded is released, and the alignment between the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 is released.

  The wiring substrate 20 to which the solar cells 40 are temporarily bonded is separated from the temporary substrate fixing jig 10, carried into the heating / pressurizing device 50, and subjected to the heating / pressurizing treatment HP. That is, the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 are not carried into the heating and pressing apparatus 50. Therefore, no heat is applied to the substrate temporary fixing jig 10 and the cell temporary fixing jig 30, and the influence of heat on the substrate temporary fixing jig 10 and the cell temporary fixing jig 30 is prevented. When the temporary substrate fixing jig 10 is used in the processing step, the temporary substrate fixing jig 10 can be used as it is without providing a cooling time for the temporary substrate fixing jig 10, so that the subsequent steps can be performed quickly.

  FIG. 5 is an enlarged schematic diagram showing a difference from solar cell module 1 according to Embodiment 1 (FIG. 3F) in the method for manufacturing solar cell module 1 according to Embodiment 3 of the present invention.

  In the method for manufacturing solar cell module 1 according to the present embodiment, adhesive 27 (insulating adhesive) is applied instead of adhesive 26 (anisotropic conductive adhesive) in the first embodiment. That is, it differs from the solar cell module 1 according to Embodiment 1 in that an adhesive 27 (insulating adhesive) is applied instead of the adhesive 26.

  1A, FIG. 1B, FIG. 1E, FIG. 1F, FIG. 2A to FIG. 2D, and FIG. 3A to FIG.

  In this embodiment, an adhesive 27 (insulating adhesive) is applied instead of the adhesive 26 applied in the first embodiment (FIGS. 1C and 1D). As the adhesive 27 (insulating adhesive), for example, an epoxy resin can be applied as in the first embodiment.

  In the first embodiment (FIGS. 3D to 3F), the wiring pattern 22 and the electrode pattern 41 are not in direct contact, whereas in the present embodiment, the wiring pattern 22 (first wiring 22p, second wiring 22n) and The electrode pattern 41 (first electrode 41p, second electrode 41n) is in direct contact (connection). That is, the first wiring 22p and the first electrode 41p, the second wiring 22n and the second electrode 41n are directly connected to each other. Therefore, in the solar cell module 1 according to the present embodiment, the adhesive 27 (insulating adhesive) disposed between the wiring pattern 22 and the electrode pattern 41 is different from the state shown in FIGS. 3D to 3F. It is made to flow into space 22s and space 41s by heating and pressurization (Drawing 5).

  In the present embodiment, the process of each step is performed in a state where the adhesive 27 is formed in advance in a region (cell region SB) corresponding to the solar cell 40 of the wiring substrate 20, so that the wiring substrate 20 and the solar cell 40 are mutually connected. The first wiring 22p and the first electrode 41p are connected by heating and pressurizing, and the second wiring 22n and the second electrode 41n are connected together. In addition, the wiring substrate 20 and the solar cell are connected. Resin sealing (resin sealing with adhesive 27) is performed between the cells 40.

  The adhesive 27 maintains an uncured state in each step before bonding the wiring substrate 20 and the solar battery cell 40, and is softened under heating and pressure (the first wiring 22p and the first electrode 41p). Between the second wiring 22n and the second electrode 41n), and flows into the space 22s and the space 41s, and the connection between the wiring pattern 22 and the electrode pattern 41 is directly performed.

Is called.

  Therefore, in the method for manufacturing solar cell module 1 according to the present embodiment, connection between first electrode 41p and first wire 22p and connection between second electrode 41n and second wire 22n are connected to wiring substrate 20 and the solar cell. Since the insulating adhesive 27 disposed between the wiring board 20 and the surroundings (space 22s, space 41s) is flowed to the surroundings (space 22s, space 41s), the insulating adhesive 26 is previously applied to the region corresponding to the solar cells 40 of the wiring board 20. Since the wiring substrate 20 can be temporarily fixed to the temporary substrate fixing jig 10 in the formed state, the wiring substrate 20 and the solar battery cell 40 can be easily and accurately bonded with a simple process. Moreover, since the insulating adhesive 27 is filled between the wiring board 20 and the solar battery cell 40, the reliability can be improved.
