Description

Technical Field

[0001] The present disclosure relates to a solar cell module and a method for manufacturing the same. Background Art

[0002] As a solar cell module having a curved surface shape, there is known one in which solar cells are sealed with a sealing material between a curved plate-shaped translucent substrate and a back surface protection member. In the manufacturing process thereof, a lamination step is performed in which a laminated body obtained by stacking these members is heated and pressed to be integrated.

[0003] Patent Document 1 discloses a solar cell module manufactured by preparing a solar cell sheet laminated such that solar cells are sandwiched between a pair of sheet-shaped members, providing a slit having a shape corresponding to the curved surface shape of the translucent substrate in the solar cell sheet, and then re-laminating the solar cell sheet so as to be sandwiched between the translucent substrate and a back surface protection member. According to Patent Document 1, in this solar cell module, solar cells can be arranged along the curved surface shape of the translucent substrate. Prior Art Literature Patent Literature

[0004] Patent Document 1 Japanese Unexamined Patent Application Publication No. 2014-96511 Summary of the Invention Problem to be Solved by the Invention

[0005] However, in the solar cell module disclosed in Patent Document 1, the lamination step has to be repeated, and an additional sealing material and an additional sheet-shaped member are required, which increases the weight of the solar cell module. In addition, the slits provided in the solar cell sheet have different shapes for each space between adjacent solar cell strings, so the manufacturing method is complicated and is considered unsuitable for mass production.

[0006] Incidentally, a solar cell module can be manufactured by laminating a laminate in which a translucent substrate, a translucent substrate-side encapsulant, a solar cell matrix, a back-side protective member-side encapsulant, and a back-side protective member are stacked in that order. The solar cell matrix is ​​made by arranging multiple solar cell strings, each consisting of multiple adjacent solar cells connected in series along a first direction, adjacent to each other along a second direction perpendicular to the first direction, and then wiring them together.

[0007] In the manufacturing process of typical flat-plate solar cell modules, when creating the solar cell matrix, the solar cells are secured with tape to prevent the distance (spacing) between solar cell strings from widening due to the pressure applied during the lamination process. This tape uses a transparent, thin substrate so that it is not noticeable to the appearance of the solar cell module.

[0008] An example of such tape fastening is shown in Figure 8. Figure 8 is a schematic rear view of a solar cell matrix 91M in which solar cell strings 91S are fixed together with tape 93, as a comparative example. Multiple solar cells 91 are electrically connected by connecting members (not shown) so that current flows along the path of arrow E2 shown in Figure 8.

[0009] As shown in Figure 8, in the solar cell matrix 91M, some of the pairs of ends of adjacent solar cell strings 91S are connected by wiring members 94 (busbars in this example). Near the locations where the wiring members 94 are connected, the distance between adjacent solar cell strings 91S is fixed by these wiring members 94, but in other locations, the distance between adjacent solar cell strings 91S is not fixed.

[0010] Therefore, to prevent the distance between solar cell strings 91S from widening due to the pressure applied during the lamination process, tapes 93 are installed between adjacent solar cells 91 along the second direction.

[0011] Even with curved solar cell modules, the manufacturing process involves creating the solar cell matrix on a flat surface for productivity reasons, and then placing it on a curved, translucent substrate. This results in significant stress being applied to the solar cell matrix during the lamination process, leading to various problems such as cell cracking and misalignment of the solar cell strings.

[0012] Figure 9 is a schematic diagram showing how a solar cell 91 breaks, and Figure 10 is a schematic diagram showing how the solar cell string 91S is misaligned. As shown in Figure 9, the convexly curved translucent substrate 92 has two main surfaces: a convex main surface 921 which is a convex curved surface, and a concave main surface 922 which is a concave curved surface.

[0013] As shown in Figure 9, when a solar cell matrix 91M fabricated on a flat surface is placed on the concave main surface 922 of a translucent substrate 92 and pressurized, a force is applied that causes the solar cell 91 to bend, which can result in cell cracking of the solar cell 91.

[0014] Furthermore, because a force is applied that pushes the solar cell matrix 91M apart, the solar cell string 91S may move as shown by the arrow in Figure 10, causing a displacement of the solar cell string 91S.

[0015] In particular, as shown in Figure 8, if tape 93 is installed between solar cells 91, the distance between adjacent solar cell strings 91S cannot expand in accordance with the curved shape of the translucent substrate 92, making it easier for cell cracking to occur, as shown in Figure 9. Conversely, if the solar cells 91 are not fixed with tape or the like to prevent cell cracking, the solar cell strings 91S are prone to misalignment in various directions, as shown in Figure 10, because they are placed on a curved translucent substrate 92.

[0016] Due to these circumstances, conventional solar modules for automotive and other applications have only installed solar cells in areas with a large radius of curvature (for example, areas with a radius of curvature of 5m). However, this limits the area where solar cells can be installed, making it difficult to expect large amounts of power generation. Therefore, there is a demand for solar modules that can install solar cells in areas with a small radius of curvature as well, in order to increase the area where solar cells can be installed.

[0017] This disclosure has been made in view of the above-mentioned problems, and aims to provide a solar cell module and a method for manufacturing the same that can suppress cell cracking, where solar cells break, and displacement of solar cell strings, by increasing the distance between adjacent solar cell strings in accordance with the curved shape of the translucent substrate. [Means for solving the problem]

[0018] To solve the above problems, the following solar cell module and method for manufacturing the same are provided.

[0019] The solar cell module disclosed herein is A solar cell module in which a solar cell matrix is ​​sealed between a convexly curved translucent substrate and a back-side protective member, The solar cell matrix includes a plurality of solar cell strings in which a plurality of adjacent solar cells are connected in series along a first direction. Multiple solar cell strings are arranged adjacent to each other along a second direction perpendicular to the first direction, A pair of adjacent ends of the solar cell string along the second direction includes a connected pair in which the ends are connected by a wiring member and a non-connected pair in which the ends are not connected by a wiring member. A bridge member is provided to span between adjacent wiring members along the second direction, or between solar cells located at the ends of the unconnected pair. A distance between the adjacent solar cell strings along the second direction changes in accordance with a curved shape of the translucent substrate, and is minimized at the end portion.

[0020] In the above solar cell module, the bridging member may be an insulating tape.

[0021] In the above solar cell module, the translucent substrate may have a curved shape including a portion where a radius of curvature is smaller than 3 m in a region overlapping with the solar battery cell in a plan view.

[0022] In the above solar cell module, it is preferable that no bridging member bridging the adjacent solar cells along the second direction is provided except between the solar cells located at the end portion in the non-connected pair.

[0023] A method for manufacturing the above solar cell module includes: a matrix manufacturing step of manufacturing the solar cell matrix; a placing step of placing a translucent substrate side sealing material, the solar cell matrix, a back surface protection member side sealing material, and the back surface protection member in this order on the translucent substrate with a concave main surface facing upward, to manufacture a laminated body; a laminating step of heating and pressurizing the laminated body to integrate the components; and characterized by comprising the above steps.

[Modes for carrying out the invention]

[0026] The embodiments of this disclosure will be described in detail below with reference to the drawings. In the description of each figure, the directions referred to as the first and second directions (D1 and D2, respectively in the figures) are used. In the solar cell module of this disclosure, the first direction refers to the direction in which multiple solar cells are adjacent to each other in a solar cell string, and the second direction refers to the direction perpendicular to the first direction, in which multiple solar cell strings are adjacent to each other. The directions in the figures showing the manufacturing process and components of the solar cell module correspond to the directions in the completed solar cell module.

[0027] In this disclosure, the surface of a solar cell module that is primarily exposed to sunlight will be described as the light-receiving surface, and the opposite surface will be described as the back surface. Common reference numerals are used for components common to each embodiment, and detailed descriptions of these components will not be repeated.

[0028] Note that in the diagrams showing the solar cell module and solar cell matrix, the connecting members that electrically connect multiple solar cells constituting a solar cell string, and the connecting members that electrically connect solar cells to wiring members are not shown.

[0029] Figure 1 is a schematic rear view showing the solar cell matrix 11M included in the solar cell module 10 according to this embodiment, Figure 2 is a schematic perspective view showing the general configuration of the solar cell module 10 according to this embodiment, and Figure 3 is a schematic partial cross-sectional view along the second direction showing the general configuration of the solar cell module 10 according to this embodiment. Note that in Figure 2, components other than the solar cells 11 among the components constituting the solar cell matrix 11M are omitted from the illustration.

[0030] In this embodiment, a solar cell module 10 having a curved shape as shown in Figure 2 is manufactured by sealing the solar cell matrix 11M shown in Figure 1 between a convexly curved translucent substrate 12 and a back surface protective member 16.

[0031] Specifically, as shown in Figure 3, the solar cell module 10 has a structure in which the solar cell matrix 11M is sealed with a sealing material 15 between the light-transmitting substrate 12 and the back surface protective member 16.

[0032] The sealing material 15 consists of a light-transmitting substrate side sealing material 151 located on the light-transmitting substrate 12 side of the solar cell matrix 11M, and a back-side protective member side sealing material 152 located on the back-side protective member 16 side of the solar cell matrix 11M.

[0033] The light-transmitting substrate 12 can be any material that has the property of transmitting light, for example, a glass substrate can be used. The back surface protective member 16 can be any material that can protect the back side of the sealing material 15, for example, a weather-resistant film (back sheet) such as PET or a glass substrate can be used. The sealing material 15 is made of a resin material or the like that has the property of transmitting light.

[0034] This solar cell module 10 is (1) A solar cell matrix fabrication process for fabricating the solar cell matrix 11M, (2) A mounting step to create a laminate by placing a translucent substrate side sealing material 151, a solar cell matrix 11M, a back surface protective member side sealing material 152, and a back surface protective member 16 in this order on a translucent substrate 12 with the concave main surface 122 facing upward, (3) A lamination process in which the laminate prepared in the placement process is heated and pressurized to integrate it, It is manufactured using a manufacturing method that includes [specific process details]. Therefore, this process will be explained in order with reference to the drawings.

[0035] <Solar cell matrix fabrication process> In the solar cell matrix fabrication process, the solar cell matrix 11M shown in Figure 1 is fabricated. This solar cell matrix 11M is fabricated on a flat surface.

[0036] As shown in Figure 1, the solar cell matrix 11M includes multiple solar cell strings 11S in which multiple adjacent solar cells 11 are connected in series along a first direction, and the multiple solar cell strings 11S are arranged adjacent to each other along a second direction perpendicular to the first direction. In the solar cell strings 11S, multiple adjacent solar cells 11 along the first direction are connected in series by wiring members (not shown).

[0037] After arranging multiple solar cell strings 11S on a plane in this manner, some of the pairs of adjacent solar cell string ends 11S along the second direction are electrically connected to each other with a wiring member 14 (busbar in this example). The wiring member 14 is formed in the shape of a strip extending linearly in the second direction D2. The busbar, as the wiring member 14, is a flat conductor and is made of metal (for example, copper).

[0038] Specifically, in order to connect multiple solar cells 11 in series so that current flows along the path of arrow E1 shown in Figure 1, the ends of the solar cell string 11S are electrically connected with wiring members 14. The ends of the solar cell string 11S and the wiring members 14 are connected by wiring members not shown.

[0039] As a result, in this example, pairs of solar cell string 11S ends connected to each other by wiring members 14 (hereinafter also referred to as connected pairs) and pairs of solar cell string 11S ends not connected to each other by wiring members 14 (hereinafter also referred to as unconnected pairs) alternate along the second direction, and multiple wiring members 14 are provided at intervals along the second direction.

[0040] Furthermore, in the solar cell matrix manufacturing process according to this embodiment, as shown in Figure 1, a support member 13 is provided that spans between adjacent wiring members 14 along the second direction. By providing the support member 13 in this way, either the wiring member 14 or the support member 13 is spanned between the ends of adjacent solar cell strings 11S along the second direction.

[0041] Figure 4 shows a modified example of the solar cell matrix 11M shown in Figure 1. In this modified example, the support member 13 is installed between solar cells 11 located at the ends of the solar cell string 11S in the unconnected pair. Even when installed in this position, either the wiring member 14 or the support member 13 will be stretched between the ends of adjacent solar cell strings 11S along the second direction.

[0042] In this embodiment, insulating tape is used as the mounting member 13. When tape is used as the mounting member 13, the tape is applied so as to span across adjacent wiring members 14 along the second direction (in the modified example shown in Figure 4, between solar cells 11 located at the ends of the solar cell string 11S in the unconnected pair).

[0043] It is preferable that the mounting members 13 be stretched across the back side of each member so that they are not easily visible when the solar cell module 10 is viewed from the light-receiving side. Therefore, in this embodiment, the tape serving as the mounting member 13 is attached to the back side of each member.

[0044] Examples of base materials for the tape used as the erection member 13 include, for example, a transparent PET resin base material, as well as polypropylene, polyurethane, and polyester resins. Examples of adhesives for the tape include transparent adhesives such as acrylic adhesives and silicone adhesives. The erection member 13 may take a form other than tape, as long as it can suppress the widening of the distance between the members that are stretched across it.

[0045] Alternatively, the tape used as the erection member 13 may be one that is not transparent, but the same color as or a similar color to the backsheet used as the backing protective member 16. Note that a similar color refers to a color adjacent to the target color in the Munsell color circle.

[0046] When a mounting member 13 is installed between adjacent wiring members 14, as shown in Figure 1, the mounting member 13 and the wiring members 14 can be easily shielded by covering them together with a shielding member (for example, a sheet-like member such as a resin film) of the same or similar color as the back sheet used as a back surface protection member 16, or by painting a translucent substrate 12 on the positions where the mounting member 13 and wiring members 14 are visible when the solar cell module 10 is viewed from the light-receiving surface side. From the viewpoint of appearance quality, the configuration shown in Figure 1 is preferable.

[0047] Furthermore, in Figure 8, which is a comparative example as described above, tapes 93 that span adjacent solar cells 91 along the second direction are evenly provided up to the center of the solar cell matrix 91M. In contrast, in the fabrication of the solar cell matrix 11M according to this embodiment, as shown in Figure 1 or Figure 4, no support members 13 are provided in the center of the solar cell matrix 11M.

[0048] In other words, in the configuration shown in Figure 1, no bridging members (specifically, tapes) are provided to connect adjacent solar cells 11 along the second direction, and in the configuration shown in Figure 4, no bridging members are provided to connect adjacent solar cells 11 along the second direction except between solar cells 11 located at the ends of the solar cell string 11S in the unconnected pair.

[0049] The reason is as follows. In the manufacturing method of the solar cell module 10 according to this embodiment, as shown in Figure 7, when the solar cell matrix 11M is placed on the curved translucent substrate 12, the distance between adjacent solar cell strings 11S along the second direction widens in accordance with the curved shape of the translucent substrate 12. Therefore, it is possible to suppress cell cracking, where the solar cell 11 cracks, and displacement of the solar cell strings 11S during the lamination process. In contrast, as shown in Figure 8, when a tape 93 is provided that spans adjacent solar cells 91 along the second direction, the widening of the distance between adjacent solar cell strings 91S in accordance with the curved shape of the translucent substrate 92 is restricted.

[0050] Furthermore, as shown in Figures 1, 4, and 7, both ends of all solar cell strings 11S are fixed with mounting members 13 or wiring members 14, which prevents the solar cell strings 11S from shifting in various directions due to the pressure applied during the lamination process, as shown in Figure 10.

[0051] <Placement process / Lamination process> In the mounting process, a laminate is fabricated by mounting the translucent substrate side sealant 151, the solar cell matrix 11M, the back surface protective member side sealant 152, and the back surface protective member 16 in that order on a translucent substrate 12 with the concave main surface 122 facing upward. That is, the components are mounted in order from the light-receiving surface side of the solar cell module 10, with their back surfaces facing upward.

[0052] The light-transmitting substrate-side sealing material 151 and the back-side protective member-side sealing material 152 are sheet-like members made of resin material or the like that has light-transmitting properties. They soften when heated and pressurized during the lamination process, so that the solar cell matrix 11M is sealed between the light-transmitting substrate 12 and the back-side protective member 16. The softened resin hardens again, integrating the laminate and manufacturing the solar cell module 10.

[0053] Figure 5 is a perspective view of the translucent substrate 12, and Figure 6 is a schematic diagram showing the solar cell matrix 11M being placed on the translucent substrate 12 during the mounting process. In Figure 6, the support members 13 in the solar cell matrix 11M are shown as curved, but the support members 13 may also be in a non-curved form.

[0054] As shown in Figure 5, the translucent substrate 12 is curved in a convex shape, and more specifically, it may be a plate-like member having a three-dimensional curved surface shape that is curved along two mutually orthogonal directions (see dashed lines in Figure 5). Therefore, the translucent substrate 12 has a convex main surface 121 which is a convex curved surface and a concave main surface 122 which is a concave curved surface.

[0055] In the mounting process according to this embodiment, first, as shown in Figure 6, the translucent substrate 12 is placed with the concave main surface 122 facing upward. After the translucent substrate side sealing material 151 is placed on the translucent substrate 12, the solar cell matrix 11M, which was manufactured (i.e., wired) in the solar cell matrix manufacturing process, is then placed on top of it.

[0056] Note that the solar cell 11 shown in Figure 6 is a solar cell 11 located at the end of a solar cell string 11S, and each corresponds to a different solar cell string 11S. In other words, the multiple solar cells 11 that make up a row of solar cell strings 11S are arranged along the back of the page.

[0057] In the mounting process, as shown in Figure 6, the back surface protective member side sealing material 152 is placed on the solar cell matrix 11M, and then the back surface protective member 16 is placed on top of that. The laminate, with the components mounted in this order, is heated and pressurized in the lamination process, causing the laminate to integrate and producing a solar cell module 10 in which the solar cell matrix 11M is sealed with sealing material 15, as shown in Figure 3.

[0058] Incidentally, conventional lamination processes, which involve placing a solar cell matrix on a curved substrate, have problems such as cell cracking (where the solar cells break) and misalignment of the solar cell strings, as mentioned above. For this reason, in solar cell modules for automotive applications, solar cells were only installed in areas with a large radius of curvature (for example, areas with a radius of curvature of 5m).

[0059] In relation to this problem, the inventors have confirmed through experiments that, even if a single solar cell is placed on a substrate with a radius of curvature of 1 m and laminated, cell cracking does not occur. They have found that in the manufacture of solar cell modules with curved shapes, it is important not to restrain the solar cells more than necessary.

[0060] Based on this perspective, in the solar cell matrix 11M shown in Figure 1 or Figure 4, a support member 13 or a wiring member 14 is stretched between the ends of adjacent solar cell strings 11S along the second direction, limiting the variation in the distance between them. However, in the central part of the solar cell string 11S in the first direction, no member is provided to limit the variation in the distance between adjacent solar cell strings 11S along the second direction. Therefore, in the solar cell matrix 11M shown in Figure 1 or Figure 4, the distance between the ends of adjacent solar cell strings 11S along the second direction does not easily increase, while in the central part of the solar cell string 11S in the first direction, the distance between adjacent solar cell strings 11S along the second direction tends to increase.

[0061] Therefore, when the solar cell matrix 11M is placed on the concave main surface 122 of the translucent substrate 12 during the mounting process and pressure is applied during the lamination process, the distance between adjacent solar cell strings 11S changes according to the curved shape of the translucent substrate 12, except for their ends.

[0062] Figure 7 is a schematic rear view showing a solar cell matrix 11M in which the distance between adjacent solar cell strings 11S changes according to the curved shape of the translucent substrate 12. As shown by the dashed line in Figure 7, the solar cell matrix 11M takes on a natural shape along the concave main surface 122 of the translucent substrate 12.

[0063] Specifically, in Figure 7, the distance between adjacent solar cell strings 11S along the second direction widens in the central part of the solar cell string 11S in the first direction (distance d2 in Figure 7) and is minimized at the ends of the solar cell string 11S (distance d1 in Figure 7). Note that in Figure 7, the distance between adjacent solar cell strings 11S is maximum at the center of the solar cell string 11S in the first direction, but this is merely an example, and this position is also determined according to the curved shape of the translucent substrate 12. Specifically, in areas where the radius of curvature of the translucent substrate 12 is small, the distance between adjacent solar cell strings 11S will widen.

[0064] This suppresses the application of unnecessary stress to the solar cell 11 and solar cell string 11S during the lamination process, thereby preventing cell cracking of the solar cell 11 and misalignment of the solar cell string 11S. Consequently, the manufacturing method of the solar cell module 10 according to this embodiment makes it possible to manufacture solar cell modules with superior appearance and quality.

[0065] Furthermore, in this embodiment, in the portion of the concave main surface 122 where the radius of curvature is small, the distance between adjacent solar cell strings 11S along the second direction naturally increases. Therefore, in the solar cell module 10 according to this embodiment, it is possible to have a configuration that includes a portion of the translucent substrate 12 where the radius of curvature is smaller than 3m in the region that overlaps with the solar cell string 11M in a plan view.

[0066] The embodiments disclosed herein are illustrative in all respects and are not intended to be restrictive. Therefore, the technical scope of this disclosure is not construed solely by the embodiments described above, but is defined by the claims. This includes all modifications within the meaning and scope of the claims. [Explanation of Symbols]
