  Currently, research and development of clean energy is being promoted from the standpoint of securing energy resources and protecting the environment. Above all, solar cells are attracting attention because of their infinite resources (sunlight) and no pollution. Yes. Among solar cells, amorphous thin-film solar cells that are formed on a single substrate using a plasma CVD device, etc. are future solar cells because they are thin, lightweight, inexpensive to manufacture, and easy to increase in area. It will be the mainstream.

  FIG. 3 shows a plan view of the hinge attached to the side of the solar cell module with the lid removed so that the inside can be seen in a view from above, and FIG. 4 is a side sectional view in the direction of AA in FIG. Indicates.
[0038]
  3 and 4, the peripheral portion in the vicinity of the side 111 of the solar cell module 100 c is fixed to the fixing portion 201 of the hinge 200 with a screw 113, and the solar cell module is connected to the other fixing portion 202 of the hinge 200.

The knuckle 206 is provided in two places on the top and bottom of the paper to ensure the connecting and fixing of the solar cell module 100c and the solar cell module 100d and the folding operation.
[0039]
  On the other hand, a space portion 207 is formed in the central portion of the knuckle 206 provided above and below, and a power jumper 208 is disposed in the space portion 207. One end 209 of the power jumper 208 is inserted into a hole 201 a having substantially the same size as the cross-sectional shape of the power jumper 208 formed in the fixing part 201 of the hinge 200, and is led to the space area 211 of the fixing part 201.

[0042]
  Next, FIG. 5 will be described. 5 (a) and 5 (b) are cross-sectional views taken along the line AA in FIG. 3, each showing a process of folding a hinge.
[0043]
  In FIG. 5, when the solar cell module 100c and the solar cell module 100d shown in FIG. 4 are folded on the paper surface and the lower side so as to overlap each other, the hinge 200 starts to be bent with the connection pin 205 as a fulcrum, and after the folding, As shown in FIG. 5B, the back surfaces 231 and 232 of the fixing portions 201 and 202 of the hinge 200 abut. FIG. 5A shows a state before reaching FIG. In this folding process, the power jumper 208 disposed in the space portion 207 is convex on the paper surface with the fixed fulcrums 235 and 236 intersecting the surface 233 of the fixed portion 201 and the surface 234 of the fixed portion 202 as a fulcrum. It bends and forms a substantially arc shape after folding.
[0044]
  Further, in the case of deployment as shown in FIG. 4, following the reverse process described above, the power jumper 208 has a wavy form as shown in FIG. 4, for example. Therefore, the power jumper 208 apparently bends 180 degrees, and as will be understood, the power jumper 208 needs to be flexible and excellent in bending durability. According to the prototype test results, a tape-shaped electric wire with a flat foil conductive wire bonded and sealed from both sides with a polyimide resin film, an insulated braided wire with a thin braided wire covered with an insulating tube, and an electric wire using stranded copper wire It has been confirmed that the coiled electric wire formed in a coil shape can withstand a predetermined number of bending tests, and the tape electric wire is employed in this embodiment.
[0045]
  The length of the power jumper 208 located in the space 207 may be equal to or greater than the linear distance connecting the fixed fulcrums 235 and 236 in the folded state (the state shown in FIG. 5B). If the length is close, the power jumper 208 is bent at a small radius in the vicinity of the fixed fulcrums 235 and 236, so concentrated stress is applied and durability is lowered. According to the prototype test results, it was confirmed that a length that is twice to three times the linear distance withstands bending and does not protrude greatly from the space portion 207 and is appropriate. However, the length is not limited to this range, and although not shown, a bushing is engaged between the hole 201a and the power jumper 208 shown in FIGS. It is also possible to reduce the bending stress by covering the power jumper 208 in the vicinity of.
[0046]
  Further, as described above, in order to fold the solar cell module 100c and the solar cell module 100d so as to overlap each other, the central axis of the connection pin 205 is positioned slightly outside the back surface 231 and the back surface 232 of the hinge 200. Put. In other words, when the adjacent solar cell module 100c and the solar cell module 100d are overlapped, the central axis is positioned outside the outermost surface including the hinge 200 on the overlapping side. As a result, the back surface 231 and the back surface 232 are in contact with each other substantially in parallel, or are placed in parallel with a slight gap, so that the folding can be performed completely.
[0047]
  Next, a modified example of the configuration of the power jumper shown in FIGS. 6 is a side sectional view similar to FIG. 4, and FIG. 7 is a top view similar to FIG.
[0048]
  In FIG. 6, the power jumper 208 is taken upward from the upper surfaces of the fixing parts 201 and 202, and here the power jumper 208 forms a flexible overhang 208 a using a coiled electric wire. Yes. In the case of the present embodiment, when the power generation capacity of the solar cell module 100 is large, a large current flows through the power jumper 208, and there is a relatively large size and it is difficult to store in the space portion 207 in FIG. Useful. Further, the knuckle 206 of the hinge 200 is constituted by one as shown in FIG. 7, and the space portion 207 is eliminated.
[0049]
  FIG. 7 shows that the power jumper 208 is taken out from the side of the hinge 200 to form a flexible overhang 208b. In this case, the fixed fulcrum 235 of the power jumper 208 drawn from the hinge 200 is shown in FIG. Rotational torsional stress only acts on the root portions 237 and 238 corresponding to 236, and is small in stress with respect to the bending stress of the structure shown in FIG. 4 or FIG. 6, and is excellent in folding durability. Moreover, it is also possible to use a normal electric wire as it is without making it into a coil shape as the power jumper 208.
[0050]
  The hinge 200 is made of a metallic material and can be made of stainless steel, steel, or aluminum by machine cutting, sheet metal processing, pressing, or cast molding. Further, the hinge 200 is made of an organic material, an inorganic material, or a mixed material of organic and inorganic materials, and can be configured by either mechanical cutting or cast molding.

This movement can be smoothly performed without any trouble because the movable portion 330 is rotatably supported by the bearing 318 in FIG. 9 with respect to the fixed portion 310. Further, the connection and deployment between the plurality of solar cell modules 100 are performed via the hinge 200 as described above, and the electrical connection between the solar cell modules 100 can be performed without any trouble by the above-described power jumper 208. Note that the solar cell module 100 may be stored in a reverse manner of deployment.
