Description

Method for installing solar cell modules, method for removing solar cell modules, solar cell modules integrated into building materials, and solar power generation systems

[0001] The present disclosure relates to a method for attaching a solar cell module, a method for removing a solar cell module, a building material-integrated solar cell, and a solar power generation system.

[0002] BACKGROUND ART Conventionally, the mainstream of photovoltaic power generation systems is, for example, building attached photovoltaics (BAPV), which generates power from sunlight by arranging photovoltaic power generation panels on the roof of a building.

[0003] In recent years, building integrated photovoltaics (BIPV), which also function as a building material, have been adopted in some buildings. For example, in Patent Document 1, a thin-film solar cell module is arranged inside the wall of a building, and the solar cell module is a part of the wall material.

[0005] However, when a solar cell module is part of a building material, the building material must also be replaced when the solar cell module is replaced. In particular, when multiple solar cell modules are used in combination, if one solar cell module is not replaced when it becomes defective or breaks down, the efficiency of the entire solar cell may decrease.

[0006] The present disclosure provides a method for installing and removing a solar cell module, a method for removing a solar cell module, a building-integrated solar cell module that can be attached and detached to a building frame, and a solar power generation system, which allow for easy installation and removal of the solar cell module.

[0007] The solar cell module installation method disclosed herein is a method for installing a solar cell module, which includes installing a solar cell layer containing a perovskite compound on a substrate, to a vertical building frame. A first mounting member is attached to at least one of the upper and lower ends of the solar cell module. In the solar cell module installation method, a second mounting member is attached to at least one of the upper and lower ends of the building frame, a wiring storage section is attached to the second mounting member, and the first mounting member is attached to the second mounting member. Within the wiring storage section, a first lead wire of the solar cell module is connected to a first main wiring, and a second lead wire of the solar cell module is connected to a second main wiring.

[0008] The solar cell module removal method disclosed herein is a method for removing a solar cell module having a solar cell layer containing a perovskite compound on a substrate. The solar cell module has a first mounting member attached to one end and a second mounting member attached to one side of a building frame, and a wiring storage section and the first mounting member are attached to the second mounting member. In the solar cell module removal method, the first lead wire of the solar cell module is disconnected from the first main wiring in the wiring storage section, and the second lead wire of the solar cell module is disconnected from the second main wiring, and the first mounting member is removed from the second mounting member.

[0009] The building material-integrated solar cell module of the present disclosure comprises a solar cell module having a solar cell layer containing a perovskite compound on a substrate, a first mounting member attached to one end of the solar cell module, a second mounting member attached to one end of a building material frame, and a wiring storage section that is detachable from the second mounting member and extends along the second mounting member. The first mounting member and the second mounting member are detachable.

[0010] The solar power generation system of the present disclosure includes a plurality of the above-described building-integrated solar cell modules, a first main wiring connected to the positive electrode, and a second main wiring connected to the negative electrode. The solar cell modules include a first lead wire connected to the first main wiring via a connector, and a second lead wire connected to the second main wiring via a connector. The plurality of solar cell modules are connected in parallel to the first and second main wirings.

[0011] According to the disclosed method for installing a solar cell module, the method for removing a solar cell module, the building material-integrated solar cell module that can be attached and detached to a building material frame, and the solar power generation system, the building material-integrated solar cell module can be easily installed or removed.

FIG. 1 is an explanatory diagram for explaining attachment and detachment of a connector; FIG. 2 is a flowchart showing the procedure for installing a solar cell module integrated into a building material; FIG. 3 is a process diagram showing the process for installing a solar cell module integrated into a building material; FIG. 4 is a flowchart showing the procedure for removing a solar cell module integrated into a building material; FIG. 5 is a side view of a solar cell module integrated into a building material according to a modified example; FIG. 6 is a side view of a solar cell module integrated into a building material according to a modified example;

[0013] (Discovery gained by the inventors of the present application) The durability of building-integrated solar cell modules is short compared to the lifespan of a building, and if one solar cell module becomes defective or breaks down, the efficiency of the solar cell system equipped with multiple solar cell modules decreases, and as a countermeasure, the solar cell modules need to be replaced. In fact, specific consideration was needed regarding the replacement of building-integrated solar cell modules that are installed vertically, such as on window frames or verandas.

[0014] Specifically, it is necessary to reduce the load generated during wiring of solar cell modules and installation work on solar cell elements. Perovskite solar cells, which have been developed in recent years as solar cell elements, are thin films and are affected by air, so the load on the solar cell module must be taken into consideration.

[0015] Furthermore, when building-integrated solar cell modules are becoming larger and heavier, installation and wiring work becomes unstable when they are installed vertically, and it is difficult to work on balconies or near windows, and the risk increases as buildings become taller.

[0016] Therefore, we propose a method for installing a solar cell module integrated into a building material that allows for vertical installation, and a solar cell module integrated into a building material.

[0017] Specifically, both ends of the solar cell module are fixed with first and third mounting members, and are detachably fixed to second and fourth mounting members provided on the building.

[0018] This allows the solar cell module to be attached to the second and fourth mounting members fixed to the building while being structurally protected by the first and third mounting members.

[0019] The solar cell module can be installed simply by attaching the solar cell module, which is equipped with the first and third mounting members, to the second and fourth mounting members provided on the building frame from inside the balcony. Moreover, since the bus wiring is stored in the wiring storage section, workability is improved.

[0020] In addition, building specifications are diverse, and when installing solar cell modules, modules of different sizes and shapes need to be installed. This can be achieved by changing the shape and dimensions of the second and fourth mounting members.

[0021] Furthermore, even if the dimensions of the solar cell module differ, the dimensions of the solar cell module to which the first and third mounting members are attached can be maintained by adjusting the fitting length of the first and third mounting members with the recesses, making it easy to replace solar cell modules of different dimensions.

[0022] (Embodiment) Hereinafter, this embodiment will be described with reference to the drawings. In this embodiment, a case where a solar cell module is attached as part of the building material of a building 3 will be described as an example.

[0023] Currently, the useful life of buildings 3 has improved dramatically, and some buildings 3 can last for 100 years. In contrast, it is recommended that solar cell modules be replaced approximately every 10 to 20 years, and if a solar cell module is included as part of a building material, such building material also needs to be replaced every 20 years at the longest. Therefore, this disclosure describes a building material-integrated solar cell module that can be easily replaced. In this disclosure, the direction toward the outside of a building is referred to as the outside, the direction toward the inside of a building is referred to as the inside, and the direction from inside to outside is also referred to as the depth direction.

[0024] 1. Configuration of the Photovoltaic Power Generation System Please refer to Fig. 1 to Fig. 3. Fig. 1 is a partial external view of a building 3 equipped with a photovoltaic power generation system 1. Fig. 2 is an external view of a building-integrated photovoltaic module 2. Fig. 3 is a system configuration diagram of the photovoltaic power generation system 1.

[0025] As shown in FIG. 1 , the building 3 equipped with the solar power generation system 1 is, for example, a house or a building. In this embodiment, the building 3 will be described as a house. The building-integrated solar cell module 2 functions as, for example, a window or wall of the building 3. In this embodiment, the building-integrated solar cell module 2 is arranged as part of a balcony wall 5 of a balcony 4 and functions as a wall material. In this embodiment, the balcony 4 is arranged on the second floor, and the balcony wall 5 is arranged on the upper part of the exterior wall 6 between the first and second floors, but this is not limited to this. The balcony may be arranged on the first floor, or if the building 3 is an apartment building or other multi-family dwelling, it may be arranged on each floor. The building-integrated solar cell module 2 may also be arranged as part of a balcony wall.

[0026] As shown in FIG. 2 , the balcony wall 5 includes a balcony frame 7 and a building-integrated solar cell module 2 .

[0027] The balcony frame 7 supports the building-integrated solar cell modules 2. The balcony frame 7 includes an upper frame 8 that supports the upper portions of the building-integrated solar cell modules 2 and a lower frame 9 that supports the lower portions of the building-integrated solar cell modules 2. For example, six building-integrated solar cell modules 2 are attached to the balcony frame 7. The upper frame 8 of the balcony frame 7 also functions as a balcony handrail. As shown in FIG. 6 , the upper frame 8 includes a pair of flat plate portions 8b that are parallel to each other in the vertical direction and face each other, extending laterally, a flat plate portion 8c that connects the upper ends of the flat plate portions 8b and extends laterally, and a groove portion 8a surrounded by the flat plate portions 8b and 8c. The lower frame 9 includes a pair of flat plate portions 9b that are parallel to each other in the vertical direction and face each other, extending laterally, a flat plate portion 9c that connects the lower ends of the flat plate portions 9b and extends laterally, and a groove portion 9a surrounded by the flat plate portions 9b and 9c.

[0028] Referring to Fig. 3, the photovoltaic power generation system 1 includes a photovoltaic module 10 included in each of the plurality of building-integrated photovoltaic modules 2, bus wiring 51 and 52, a controller 53, and an output unit 58. The photovoltaic power generation system 1 further includes at least one of a storage battery 54, a display unit 55, an illumination unit 56, and a drive unit 57, and the output unit 58 is connected to at least one of the storage battery 54, the display unit 55, the illumination unit 56, and the drive unit 57. The output unit 58 is, for example, a distribution board.

[0029] The solar cell module 10 converts sunlight into electrical energy. A lead wire 21 extending from the positive electrode of each solar cell module 10 is connected to a bus wire 51, and a lead wire 22 extending from the negative electrode of each solar cell module 10 is connected to a bus wire 52. Multiple solar cell modules 10 are connected in parallel to the bus wires 51 and 52. The sum of the currents flowing from each solar cell module 10 is input to a controller 53. When a solar cell module 10 contains a perovskite compound in its solar cell layer PV (see FIG. 12), the voltage generated is higher than that of other solar cells. Connecting the solar cell modules 10 in parallel prevents the voltage input to the controller 53 from becoming too high. Furthermore, connecting the solar cell modules 10 in parallel allows the power generated by the remaining solar cell modules 10 to be obtained even if one of the solar cell modules 10 is damaged and no longer able to generate power. Furthermore, the solar cell modules 10 can be replaced individually. Furthermore, for design reasons, some of the six building-material-integrated solar cell modules 2 can be made of glass plates that do not contain solar cell modules 10. Although the above-mentioned effects can be obtained by connecting a plurality of solar cell modules 10 in parallel in this way, they may also be connected in series.

[0030] The controller 53 includes an integrated circuit that can be realized by semiconductor elements or the like, and a power conditioner, and converts the power converted by the solar cell module 10 into power that can be used by the storage battery 54, the display unit 55, the lighting unit 56, and the drive unit 57. The converted power is supplied to the storage battery 54, the display unit 55, the lighting unit 56, and the drive unit 57 via an output unit 58.

[0031] The storage battery 54 stores excess power that cannot be used by the display unit 55, the lighting unit 56, and the drive unit 57. The storage battery 54 supplies the stored power to the display unit 55, the lighting unit 56, and the drive unit 57 at night or on rainy days when the solar cell module 10 cannot generate power.

[0032] The display unit 55 displays an image using the supplied power. The display unit 55 is, for example, a television, a monitor, or a projector.

[0033] The lighting unit 56 emits light using the supplied power, and is, for example, an LED light or a fluorescent lamp.

[0034] The drive unit 57 uses the supplied power to drive a motor or the like. The drive unit 57 is, for example, a washing machine, an air conditioner, a refrigerator, etc. In this way, the power generated in each solar cell module 10 is stored or consumed.

[0035] Next, reference is made to Figures 4 to 6. Figure 4 is a front view of the building material-integrated solar cell module 2. Figure 5 is a side view of the building material-integrated solar cell module 2. Figure 6 is an exploded side view of the building material-integrated solar cell module 2.

[0036] The building material-integrated solar cell module 2 comprises a solar cell module 10 , a first mounting member 61 , a second mounting member 62 , a third mounting member 63 , a fourth mounting member 64 , and a wiring storage section 65 .

[0037] One vertical end portion 10a (first mounting portion) of the solar cell module 10 is fixed to the first mounting member 61, and the other vertical end portion 10b is fixed to the third mounting member 63. Here, when the solar cell module 10 is arranged vertically, the first mounting member 61 is located above the solar cell module 10, and the third mounting member 63 is located below the solar cell module 10.

[0038] The first mounting member 61 and the third mounting member 63 are attachments that support the attachment of the solar cell module 10 to the second mounting member 62 and the fourth mounting member 64, respectively, which are attached to the balcony frame 7, and are formed, for example, by bending sheet metal. They also reinforce the solar cell module 10. A building material power generation module 66 is constructed by attaching the first mounting member 61 and the third mounting member 63 to the solar cell module 10.

[0039] The first mounting member 61 has a recess 61a on its lower side for receiving one end portion 10a of the solar cell module 10, and a protruding portion 61b on its upper side. The first mounting member 61 includes flat plate portions 61c and 61d that are parallel to each other in the vertical direction and extend laterally, and a flat plate portion 61e that connects the upper ends of the flat plate portions 61c and 61d and extends laterally. The flat plate portion 61c side of the flat plate portion 61e extends upward, and the flat plate portion 61e and the protruding portion 61b form an L-shaped cross section. The outer flat plate portion 61d extends closer to the center of the solar cell module 10, downward in this case, than the inner flat plate portion 61c. The protruding portion 61b has a flat mounting surface 61ba that extends laterally outward, and a screw hole 67 that opens in a portion of the mounting surface 61ba and penetrates the protruding portion 61b in the depth direction. The screw hole 67 is an elongated hole extending in the vertical direction, and allows the vertical position of the first mounting member 61 relative to the second mounting member 62 to be adjusted.

[0040] The third mounting member 63 has a recess 61a on the upper side for receiving the other end portion 10b of the solar cell module 10, and a protruding portion 63b protruding downward. The third mounting member 63 includes flat plate portions 63c, 63d that are parallel to each other in the vertical direction and extend laterally, and a flat plate portion 63e that connects the lower ends of the flat plate portions 63c, 63d and extends laterally. The flat plate portion 63c side of the flat plate portion 63e extends downward, and the flat plate portion 63e and the protruding portion 63b form an inverted L-shaped cross section. The outer flat plate portion 63d extends closer to the center of the solar cell module 10, in this case, upward, than the inner flat plate portion 63c. The protruding portion 63b has a flat mounting surface 63ba that extends laterally outward, and a screw hole 68 that opens in a portion of the mounting surface 63ba and penetrates the protruding portion 63b in the depth direction. The screw hole 68 is an elongated hole extending in the vertical direction, and allows the vertical position of the third mounting member 63 relative to the fourth mounting member 64 to be adjusted.

[0041] The first mounting member 61 sandwiches and fixes the first surface (outer surface) 10aa and the second surface (inner surface) 10ab of the upper end portion 10a of the solar cell module 10 over the entire width direction. The third mounting member 63 sandwiches and fixes the first surface (outer surface) 10ba and the second surface (inner surface) 10bb of the lower end portion 10b of the solar cell module 10 over the entire width direction. The first mounting member 61 and the third mounting member 63 of this embodiment are adhesively fixed to the first surfaces 10aa, 10ba and the second surfaces 10ab, 10bb of the end portions 10a, 10b of the solar cell module 10, respectively, using double-sided tape or an adhesive, for example.

[0042] In this embodiment, the first mounting member 61 and the third mounting member 63 each have a space between them and the end portions 10a, 10b of the solar cell module 10, but they may be in tight contact with each other or may be filled with a caulking agent. When a space is provided between the first mounting member 61 and the third mounting member 63 and the end portions 10a, 10b of the solar cell module 10, the vertical length of this space is 5 mm to 2 cm. By providing this space, even if the vertical dimensions of the solar cell module 10 differ slightly, this space can absorb the dimensional difference.

[0043] The second mounting member 62 and the fourth mounting member 64 are each attachments that support the mounting of the building material power generation module 66 to the balcony frame 7, and are formed, for example, by bending sheet metal.

[0044] The second mounting member 62 has a first flat plate portion 62a, a second flat plate portion 62b, and a third flat plate portion 62c. The first flat plate portion 62a, which is approximately parallel to the vertical direction and extends horizontally, is inserted into and fixed to a groove portion 8a provided in the upper frame 8 of the balcony frame 7. The first flat plate portion 62a is fixed to the groove portion 8a with adhesive, caulking, or a fastening member such as a screw. The second flat plate portion 62b is approximately parallel to the vertical direction and extends horizontally. The third flat plate portion 62c is approximately parallel to the horizontal direction and extends horizontally. The inner end of the third flat plate portion 62c is connected to the lower end of the first flat plate portion 62a, and the outer end of the third flat plate portion 62c is connected to the upper end of the second flat plate portion 62b.

[0045] The second flat plate portion 62b is fixed to the mounting surface 61ba of the first mounting member 61. In this embodiment, the inner surface 62ba of the second flat plate portion 62b and the mounting surface 61ba of the first mounting member 61 are brought into contact with each other, and the first mounting member 61 is fixed to the second mounting member 62 by fastening members 81 that pass through the screw holes 67. The outer surface 62bb of the second flat plate portion 62b of the second mounting member 62 is brought into contact with the mounting plate 65a of the wiring storage portion 65, and the wiring storage portion 65 is fixed to the second mounting member 62 by fastening members 82. These fastening members 81, 82 are, for example, screws or bolts and nuts.

[0046] The wiring storage section 65 is rectangular with one side facing the building 3 (inside) open, allowing the bus wires 51, 52 to be stored from the balcony 4 side of the building 3. The wiring storage section 65 has an upwardly extending mounting plate 65a. The wiring storage section 65 protrudes away from the first mounting member 61 and has a space inside. In this embodiment, the wiring storage section 65 has a box-like shape that protrudes outward, forming a space surrounded by plates. The bus wires 51, 52 are stored within the wiring storage section 65, and the bus wires 51, 52 are placed on the bottom surface of the wiring storage section 65. The bus wires 51, 52 may be stored in a vertically overlapping manner within the wiring storage section 65. In this case, protrusion of the wiring storage section 65 can be suppressed. Because the wiring storage section 65 is located outside the building material power generation module 66, it is possible to prevent residents from accidentally touching the bus wires 51, 52.

[0047] The fourth mounting member 64 has a fourth flat plate portion 64a, a fifth flat plate portion 64b, and a sixth flat plate portion 64c. The fourth flat plate portion 64a, which is approximately parallel to the vertical direction and extends horizontally, is inserted into and fixed to a groove portion 9a provided in the lower frame 9 of the balcony frame 7. The fourth flat plate portion 64a is fixed to the groove portion 9a with adhesive, caulking, or a fastening member such as a screw. The fifth flat plate portion 64b is approximately parallel to the vertical direction and extends horizontally. The sixth flat plate portion 64c is approximately parallel to the horizontal direction and extends horizontally. The inner end of the sixth flat plate portion 64c is connected to the upper end of the fourth flat plate portion 64a, and the outer end of the sixth flat plate portion 64c is connected to the lower end of the fifth flat plate portion 64b.

[0048] The fifth flat plate portion 64b is fixed to the mounting surface 63ba of the third mounting member 63. In this embodiment, the inner surface 64ba of the fifth flat plate portion 64b and the mounting surface 63ba of the third mounting member 63 are brought into contact with each other and fixed together by fastening members 83 that pass through the screw holes 68. The fastening members 83 are, for example, screws or bolts and nuts.

[0049] The first mounting member 61, the second mounting member 62, the third mounting member 63, and the fourth mounting member 64 may each be a single continuous member or may be divided.

[0050] In this way, the solar cell module 10 is attached to the balcony frame 7, which is a vertical building frame. In this embodiment, the balcony frame 7 is not inclined relative to the vertical direction, but the vertical building frame to which the solar cell module 10 is attached may have an inclination in the range of 0 degrees to 40 degrees relative to the vertical direction.

[0051] Please refer to Figure 25. Figure 25 is a front view of two building material-integrated solar cell modules 2 arranged side by side. When the solar cell modules 10 are arranged side by side and attached to the balcony frame 7, the height of the wiring storage section 65 of each building material-integrated solar cell module 2 is also the same height, so each wiring storage section 65 forms a single tunnel-shaped wiring storage section. This makes it easy to route the bus wires 51, 52 to each wiring storage section 65.

[0052] In addition, since the solar cell modules 10 are fixed in the vertical direction but not at their lateral ends, it is possible to improve the arrangement density of the solar cell modules 10 and increase the amount of power generation. Furthermore, since they are not fixed in the lateral direction, it is possible to reduce the weight of the building material-integrated solar cell module 2.

[0053] Furthermore, since there is a gap between adjacent wiring storage sections 65, the work of connecting the lead wire 21 to the bus wire 51 and the work of connecting the lead wire 22 to the bus wire 52 can be easily performed.

[0054] 2. Configuration of Solar Cell Module Next, the basic configuration of the solar cell module 10 will be described with reference to Figs. 7 to 9. Fig. 7 is a schematic front view of the solar cell module 10. Fig. 8 is a schematic cross-sectional view of the solar cell module of Fig. 7 taken along line II-II. Fig. 9 is a schematic exploded perspective view of the solar cell module 10 of Fig. 7.

[0055] As shown in Figures 7 to 9, the solar cell module 10 comprises a first substrate 11, a second substrate 12, a plurality of sub-modules 100 corresponding to solar cell element portions, a first filler 31, and a second filler 32.

[0056] The solar cell module 10 can be used, for example, as a building material for a window, a wall, or a balcony that is arranged in a building so that external light enters from the side of the second substrate 12. In this embodiment, the solar cell module 10 is a building material for a balcony, but it may also be used as a skylight or a canopy.

[0057] The Z direction (also referred to as the "first direction") shown in Figures 7 to 9 corresponds to the thickness direction of the solar cell module 10. The thickness direction of the solar cell module 10 is, for example, the stacking direction of the two substrates 11 and 12, or the stacking direction of the solar cell layers included in the solar cell module 10. In addition, directions that intersect with each other (here, perpendicular) in a plane perpendicular to the Z direction are defined as the X direction and the Y direction. The Y direction may be, for example, the height direction of a window, and the X direction may be, for example, the width direction of the window.

[0058] The first substrate 11 and the second substrate 12 are translucent. "Translucent" means transparent to visible light. The first substrate 11 and the second substrate 12 are, for example, rectangular glass substrates (tempered glass substrates) used for building materials, and have a thickness of, for example, 2 mm or more. As shown in FIG. 7 , in a top view of the solar cell module 10 or a portion thereof, the second substrate 12 may be omitted for clarity.

[0059] 8, the first substrate 11 and the second substrate 12 are disposed so as to face each other in the Z direction. The second substrate 12, which is the light receiving side, may be thinner than the first substrate 11. The peripheral edges of the first substrate 11 and the second substrate 12 are sealed by a sealing member 50. In a plan view seen from the Z direction, the sealing member 50 is located outward from the central region 13 in which the submodule 100 is disposed. The sealing member 50 can be made of a thermoplastic elastomer such as butyl rubber.

[0060] Each of the multiple submodules 100 is a solar cell submodule having a solar cell (power generation unit). The multiple submodules 100 are located between a first substrate 11 and a second substrate 12. Each submodule 100 has, for example, a rectangular planar shape. In the example shown in FIG. 7 , the submodule 100 is disposed in a space surrounded by the first substrate 11, the second substrate 12, and the sealing member 50. The multiple submodules 100 are disposed in the central region 13 of the first substrate 11 so as not to overlap each other in a plan view seen from the Z direction.

[0061] 8, the first filler 31 is located between the first substrate 11 and the upper surface of each submodule 100. The second filler 32 is located between the second substrate 12 and the lower surface of each submodule 100. These fillers 31 and 32 may be, for example, polyvinyl butyral (PVB), ethylene vinyl acetate copolymer (EVA), polyolefin (PO), or the like.

[0062] The fillers 31 and 32 may fill the space surrounded by the first substrate 11, the second substrate 12, and the sealing member 50. This can suppress the influence of air on the solar cell layer in the submodule 100. Note that an air layer may be formed in a portion of the space other than the portion in contact with the solar cell module. In this example, the fillers 31 and 32 are arranged above and below the submodule 100, but they may be arranged on only one side.

[0063] In this embodiment, the submodules 100 are arranged in a matrix in two directions (here, the X direction and the Y direction) that intersect (here, are orthogonal) with each other in a plan view seen from the Z direction. Columns Ra to Rd, each consisting of a plurality of submodules arranged in the X direction, are called "module columns." Rows R1 to R4, each consisting of a plurality of submodules arranged in the Y direction, are called "module rows."

[0064] 7, 12 submodules 100 are arranged in four rows and three columns, constituting four module rows R1 to R4 and three module columns Ra to Rc. The multiple (four in this example) submodules constituting each module column Ra to Rc are connected in parallel. The three module columns Ra to Rc are connected in series in the X direction.

[0065] 7 , the solar cell module 10 further includes first wirings 41 a to 41 c and second wirings 42 a to 42 c extending in the Y direction between the first substrate 11 and the second substrate 12, and a plurality of third wirings 43 for connecting adjacent first wirings and second wirings. These wirings may be metal wirings. In this embodiment, these wirings are wires (tab wires) made of copper wires coated with solder.

[0066] The first wiring 41a and the second wiring 42a connect the multiple (four in this example) submodules 100 that make up the module row Ra in parallel. Similarly, the first wiring 41b, 41c and the second wiring 42b, 42c connect the multiple submodules 100 that make up the module rows Rb, Rc in parallel. In the example shown, the first wiring 41a to 41c are provided at one end of each of the module rows Ra to Rc in the X direction. The second wiring (e.g., tab wires) 42a to 42c are provided at the other end of each of the module rows Ra to Rc in the X direction.

[0067] The plurality of third wirings 43 connects two adjacent module rows in series among the three module rows Ra to Rc, and are arranged so as to connect the first wiring of one of the two adjacent module rows to the second wiring of the other module row.

[0068] 7 , the solar cell module 10 further includes a pair of lead wires 21, 22. The lead wires 21, 22 are, for example, metal wiring (e.g., tab wires). The lead wires 21, 22 are electrically connected to the submodule 100 within a space surrounded by the first substrate 11, the second substrate 12, and the sealing member 50. The lead wires 21, 22 may be drawn from within the space to the outside, passing through the sealing member 50.

[0069] 7 , the lead wire 21 is electrically connected to one end of the first wiring 41 a of the leftmost module row Ra. The lead wire 22 is electrically connected to one end of the second wiring 42 c of the rightmost module row Rc. The lead wire 21 may be an extended portion of the first wiring 41 a, and the lead wire 22 may be an extended portion of the second wiring 42 c.

[0070] 10 to 13, the structure of the submodule 100 in the solar cell module 10 will be described. Here, one submodule in the module row Ra (FIG. 7) will be described as an example.

[0071] Fig. 10 is a schematic top view of one submodule in a solar cell module. Fig. 11 is an enlarged top view of a portion of the submodule in Fig. 10. Fig. 11 shows an enlarged view of region 100a shown in Fig. 10. Fig. 12 is an enlarged cross-sectional view taken along line VIA-VIA in Fig. 11. Fig. 13 is an enlarged cross-sectional view taken along line VIB-VIB in Fig. 11.

[0072] 10 , each submodule 100 includes a light-transmitting base substrate 110, a power generation unit supported by the base substrate 110, and a pair of wirings 141 and 142. In the example shown in FIG. 10 , the power generation unit includes a plurality of linear strings 120.

[0073] The base substrate 110 is, for example, a rectangular glass substrate. The power generating section is located on a part of the main surface 110 s of the base substrate 110 .

[0074] The power generating unit includes at least a solar cell layer. As described below, the power generating unit has a laminated structure including at least a pair of transparent electrodes and a solar cell layer located between the pair of transparent electrodes. The laminated structure only needs to be supported by the main surface 110s of the base substrate 110, and does not need to be in direct contact with the main surface 110s.

[0075] The wiring 141 is arranged on one end side of the base substrate 110. The wiring 142 is arranged on the other end side of the base substrate 110. In this example, the wirings 141 and 142 are arranged at both ends of the base substrate 110 in the X direction. The wirings 141 and 142 are electrically connected to the power generation unit. The wirings 141 and 142 are connected to the wirings 141 and 142 of other submodules (not shown) adjacent in the Y direction, respectively, to form the first wiring 41a and the second wiring 42a.

[0076] A plurality of strings 120, which are power generating units, are connected in parallel by wiring 141 and 142. Here, each string 120 extends in the X direction from one end to the other end of the base substrate 110. One end of each string 120 is connected to wiring 141, and the other end is connected to wiring 142.

[0077] The multiple strings 120 are arranged on the main surface 110s of the base substrate 110 at a distance from each other in the Y direction. In a plan view seen from the Z direction, the multiple strings 120 may extend, for example, parallel to each other. In a plan view seen from the Z direction, regions 130 of the main surface 110s of the base substrate 110 located between adjacent strings 120 are referred to as "inter-string regions."

[0078] As shown in FIGS. 11 and 12, each of the plurality of strings 120 is a solar cell element string having a plurality of solar cell elements 150 connected in series.

[0079] As shown in FIGS. 12 and 13 , each string 120 has a stacked structure L in which multiple layers, including a lower transparent conductive layer LE, a solar cell layer PV, and an upper transparent conductive layer UE, are stacked in the Z direction. These layers are supported by the main surface 110s. In the stacked structure L, the solar cell layer PV is located between the lower transparent conductive layer LE and the upper transparent conductive layer UE. The lower transparent conductive layer LE is located on the base substrate 110 side of the solar cell layer PV. The solar cell layer PV is a thin-film type, and is, for example, a stacked film including, from the base substrate 110 side, an n-type semiconductor layer, an i-type semiconductor layer, and a p-type semiconductor layer. The solar cell layer PV may further include an electron transport layer and / or a hole transport layer, as necessary.

[0080] The lower transparent conductive layer LE, solar cell layer PV, and upper transparent conductive layer UE are separated for each solar cell element 150. In this example, the solar cell layer PV and the upper transparent conductive layer UE are separated for each solar cell element 150 by a separation groove 160. The lower transparent conductive layer LE includes a lower transparent electrode 151 of each solar cell element 150. The upper transparent conductive layer UE includes an upper transparent electrode 155 of each solar cell element 150. The solar cell layer PV includes a semiconductor layer 153 of each solar cell element 150.

[0081] Each solar cell element 150 has a lower transparent electrode 151, an upper transparent electrode 155, and a semiconductor layer 153 located between the lower transparent electrode 151 and the upper transparent electrode 155. The lower transparent electrode 151 (or the upper transparent electrode 155) of the solar cell element 150 located at one end of each string 120 is electrically connected to the wiring 141. Similarly, the upper transparent electrode 155 (or the lower transparent electrode 151) of the solar cell element 150 located at the other end of each string 120 is electrically connected to the wiring 142.

[0082] The solar cell layer PV (i.e., the semiconductor layer 153) is a layer (photoelectric conversion layer) that converts absorbed light into electricity. The solar cell layer PV contains, for example, a perovskite compound (perovskite semiconductor) as a photoelectric conversion material. The perovskite compound is represented by the chemical formula ABX ３and structures having crystals similar thereto. A is a monovalent cation, B is a divalent cation, and X is a halogen anion. The lower transparent conductive layer LE and the upper transparent conductive layer UE are light-transmitting metal oxide layers such as indium tin oxide (ITO), indium zinc oxide (IZO), or fluorine-doped tin oxide (FTO). Note that the materials for each layer constituting the solar cell element are not limited to those described above, and known materials may be used.

[0083] 14 and 15, the connection between the lead wires 21, 22 of the solar cell module 10 and the bus wires 51, 52 will be described. Fig. 14 is an explanatory diagram illustrating the connection between the bus wires 51, 52 and the lead wires 21, 22 of the solar cell module 10. Fig. 15 is an explanatory diagram illustrating the attachment and detachment of connectors. Fig. 15(a) shows a state in which the male connector 71 and the female connector 72 are detached. Fig. 15(b) shows a state in which the male connector 71 and the female connector 72 are connected.

[0084] Different types of connectors are connected to the positive lead wire 21 and the negative lead wire 22 of the solar cell module 10. For example, a male connector 71 is connected to the tip of the lead wire 21, and a female connector 72 is connected to the tip of the lead wire 22.

[0085] Bus wires 51 and 52 are provided with terminal boxes 73 from which lead wires 51 a and 52 a branch off, respectively. Different types of connectors are connected to lead wire 51 a branching off from positive bus wire 51 and lead wire 52 a branching off from negative bus wire 52. For example, a female connector 72 is connected to the tip of lead wire 51 a, and a male connector 71 is connected to the tip of lead wire 52 a.

[0086] In this way, since the types of connectors connected to the positive lead wire and the negative lead wire are different, it is possible to prevent the positive and negative wires from being connected incorrectly when connecting to the bus wiring 51, 52 when installing or replacing the solar cell module 10.

[0087] The male connector 71 has, for example, two claws 71a at its tip, and the female connector 72 has, at its tip, a recess 72a that can engage with the claws 71a. The male connector 71 can be connected to the female connector 72 by fitting the claws 71a of the male connector 71 into the recesses 72a of the female connector. The male connector 71 can be removed from the female connector 72 by disengaging the claws 71a of the male connector 71 from the recesses 72a of the female connector. Because the male connector 71 and the female connector 72 can be easily attached and detached, even someone who is not a professional electrician can attach and detach the solar cell module 10 to and from the bus wiring 51, 52.

[0088] 5. Method for Mounting and Removing a Building Material-Integrated Solar Cell Module Next, a method for mounting a building material-integrated solar cell module of this embodiment will be described with reference to Figures 16 to 18. Figure 16 is a flowchart showing the mounting procedure for a building material-integrated solar cell module. Figures 17 and 18 are process diagrams showing the mounting process for a building material-integrated solar cell module.

[0089] In step S1, as shown in Figure 17(a), the worker fixes the second mounting member 62 to the upper frame 8 of the balcony frame 7, and fixes the fourth mounting member 64 to the lower frame 9 of the balcony frame 7. Once the second mounting member 62 and the fourth mounting member 64 are fixed to the balcony frame 7, they can be used as is the next time the building material power generation module 66 is replaced.

[0090] In step S2, as shown in Figure 17(b), the worker attaches the wiring storage section 65 to the second mounting member 62 using fastening members 82. At this time, the worker can attach the wiring storage section 65 from the balcony 4 side, which improves the safety of the attachment. In this embodiment, the worker secures the wiring storage section 65 by tightening screws from the balcony 4 side.

[0091] 17(c), the worker stores the bus wires 51 and 52 in the wire storage section 65. Once the bus wires 51 and 52 are stored in the wire storage section 65, they can be used as they are the next time the building material power generation module 66 is replaced.

[0092] In step S4, as shown in FIG. 18(a), the worker temporarily fastens the fastening members 81 and 83 to temporarily fix the building material power generation module 66 to the second mounting member 62, and connects the bus wiring 51 and 52 to the lead wires 21 and 22, respectively.

[0093] 18(b), the worker fully fastens the building material power generation module 66 to the second mounting member 62 by fully tightening the fastening members 81 and 83. This completes the installation of the building material-integrated solar cell module 2. Note that step S5 may be performed first, and then the bus wiring 51 and 52 and the lead wires 21 and 22 may be connected, respectively, in step S4.

[0094] Next, a method for removing the solar cell module of this embodiment will be described with reference to Fig. 19. The removal method is basically the reverse of the above-described installation method.

[0095] In step S11, as shown in FIG. 18(a), the worker loosens the screw fastening members 81 and 83 to loosen the fastening of the building material power generation module 66 to the second mounting member 62.

[0096] In step S12, the worker removes the lead wires 21 and 22 from the bus wires 51 and 52.

[0097] 17(c), the worker completely removes the screw fastening members 81, 83 to remove the building material power generation module 66 from the second mounting member 62. Next, by attaching a new building material power generation module 66, it is possible to easily replace only the solar cell module 10 without replacing the balcony frame 7, the second mounting member 62, the fourth mounting member 64, and the bus wiring 51, 52.

[0098] Furthermore, according to this embodiment, even if the size of the solar cell module 10 has manufacturing errors, the difference in size can be absorbed when attaching it to the first mounting member 61 and the third mounting member 63. Furthermore, if the sizes of the solar cell modules 10 differ greatly, they can be adapted to the same size of balcony frame 7 by using first mounting members 61 and third mounting members 63 of different sizes, as shown in Figure 20.

[0099] The solar cell module 10K shown in Figure 20 has a smaller vertical size than the solar cell module 10 shown in Figure 5, but by using a first mounting member 61K and a third mounting member 63K which have a larger vertical size, the building material power generation module 66K can be attached to the same second mounting member 62 and fourth mounting member 64.

[0100] [6. Effects, etc.] As described above, the building material-integrated solar cell module 2 comprises a solar cell module 10 having solar cell layers provided on first substrate 11 and second substrate 12, a first mounting member 61 attached to one end of solar cell module 10, a second mounting member 62 attached to one side of the balcony frame 7, and a wiring storage section 65 that is detachable from second mounting member 62 and extends along the balcony frame 7. The first mounting member 61 and the second mounting member 62 are detachable.

[0101] By attaching the detachable first mounting member 61 to the solar cell module 10 and the second mounting member 62 attached to the balcony frame 7, which is a building material frame, the solar cell module 10, which also functions as a building material, can be easily attached and detached to the balcony frame 7. Even if the replacement cycle of the solar cell module 10 is shorter than the useful life of the building material frame, the solar cell module 10 can be easily attached and detached, making it easy to replace the solar cell module 10.

[0102] Since the solar cell module 10 can be easily replaced on the balcony frame 7, a solar cell layer PV with high power generation efficiency can always be mounted. Also, by replacing the solar cell module 10, the exterior design of the balcony wall 5 can be freely changed.

[0103] (Other Embodiments) As described above, the above embodiment has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate. Therefore, other embodiments will be described below as examples.

[0104] In the above embodiment, both bus wires 51, 52 are stored in the wiring storage section 65 attached to the second mounting member 62, but this is not limiting. As shown in Fig. 21 , the positive bus wire 51 may be stored in the wiring storage section 65 attached to the second mounting member 62, and the negative bus wire 51 may be stored in the wiring storage section 85 attached to the fourth mounting member 64. In this case, the lead wire 21 extends from the top of the solar cell module 10, and the lead wire 22 extends from the bottom of the solar cell module 10. This prevents a worker from mistakenly connecting the positive and negative wires when connecting the bus wires and the lead wires.

[0105] In the above embodiment, the building-integrated solar cell module 2 was the balcony wall 5 of the balcony 4, but this is not limited thereto. As shown in FIG. 22 , the building-integrated solar cell module 2L may be a window 86. For example, the inner window of a double-glazed window 86 may be the building-integrated solar cell module 2L. A window frame 87 has two recesses 87a and 87b in the depth direction, and a second mounting member 62 and a fourth mounting member 64 are fixed to the inner recess 87a. A building-integrated solar cell module 66 is attached to the second mounting member 62 and the fourth mounting member 64. A glass plate 88 serving as a window is fixed to the recess 87b at the rear of the window frame 87. Note that the window 86 may be a single window. As shown in FIG. 23 , the second mounting member 62 and the fourth mounting member 64 can be directly attached to the inner side of the window frame 87 with fastening members 89 to convert the single window into a double-glazed window.

[0106] In the above embodiment, the solar cell module 10 is located inside the balcony frame 7, but this is not limited to this. As shown in Figure 24, the solar cell module 10 may be located directly below the upper frame 8 of the balcony frame 7.

[0107] In the above embodiment, the solar cell layer PV (see FIG. 12) of the solar cell module 10 contains a perovskite compound, but this is not limiting. The solar cell module 10 may contain a silicon-type solar cell layer.

[0108] In the above embodiment, the wiring storage section 65 is disposed outside the second mounting member 62 , but this is not limiting. The wiring storage section 65 may be disposed inside the second mounting member 62 .

[0109] In the above embodiment, the bus wires 51, 52 and the lead wires 21, 22 of the solar cell module 10 are connected via a male connector 71 and a female connector 72, but this is not limited thereto. As shown in Fig. 26 , the lead wire 21 of the solar cell module 10 may be connected to a terminal box 75, and the lead wire 22 may be connected to a terminal box 76. The terminal boxes 75, 76 are each disposed at the upper end of the solar cell module 10, and an opening or cutout is formed in the location of the corresponding wiring storage section 65, and the terminal boxes 75, 76 are stored in the wiring storage section 65. In the wiring storage section 65, the lead wire 51a branching off from the positive bus wire 51 is connected to the terminal box 75, and the lead wire 52a branching off from the negative bus wire 52 is connected to the terminal box 76.
