Solar cell elements have the function of converting light energy into electrical energy, but since a single solar cell element cannot generate a large amount of power, in order to obtain the desired power,
A common method is to mount a solar cell array in which a required number of solar cell elements are electrically connected in series and parallel on a substrate called a substrate.

Conventional embodiments are shown in FIGS. 5 and 6. FIG. 5 shows the mounting surface of the solar cell elements 2, and a solar cell array in which 4 solar cell elements 2 are connected in series and 2 in parallel is mounted on the substrate 1.
Module is implemented. The output of each array is transmitted from the interconnector 3 through the wiring material 4 to the board 1 through the through hole 5.
It is pulled out to the back side. FIG. 6 is a back view of FIG. 5. The wiring members 4 of each array are gathered at the edge of the substrate 1. The wiring material 4 is fixed to the substrate 1 with an adhesive 6).

However, in such a conventional wiring processing method, it is necessary to make a large number of through holes 5 on both sides of the board 1,
Further, the space for this is a waste of space from the viewpoint of mounting efficiency of the solar cell element, and this leads to an increase in the weight of the armpit. Since satellites and the like are required to be as light and compact as possible, a small increase in the area and weight of solar panels poses a major problem.

Furthermore, if a large amount of electric power is required, the size of the 9-channel will naturally increase, and accordingly, the length and number of wiring members 4 will increase, resulting in an increase in the weight of the wiring. Another disadvantage is that it requires more time and effort to fix the wiring and to drill holes.

FIG. 1 shows an embodiment of the present invention, in which a solar cell element 2 is placed on a substrate 1.
The implementation method is the same as the conventional method. That is,
Eight solar cell elements 2 constitute a four-series, two-parallel array, and five modules corresponding to each play are fixed to the substrate 1 with adhesive. The side and back surface of this board 1 have a third
A transmission sheet 9 is provided as shown in the figure. in this case,
On the back surface of the substrate 1, an insulating section 10 without a transmission sheet is provided at the center along both side surfaces. As shown in FIG. 2, the transmission sheet 9 is constructed by providing a conductive portion 1 on the surface K of an insulating sheet 8, on which a conductive material such as metal is deposited or a thin conductive plate is adhered. The solar cell elements 2 are electrically connected to each other by interconnectors 3 for each array. One end of the wiring material 4 is connected to the interconnector 3 at both ends of each 7-lay, and the other end of the wiring material 4 is connected to the conductive portion 7 of the transmission sheet 9 provided on the side surface of the board I.
Connect to. As a result, the positive and negative outputs of each solar cell element 2 are taken out to the conductive parts 2 on both sides of the substrate 10.

According to the above configuration, a large-area conductor such as the conductive portion 7 of the transmission sheet 9 can be used as a transmission path for the power generated from each solar cell element 2, so that direct current resistance is small and transmission loss can be reduced. Further, the transmission sheet 9 can be made very light by using the conductive portion 7 in which a conductor is deposited on the insulating sheet 8 such as an insulating film. Furthermore, when solar panels on satellites reach high temperatures, the power generated by the solar cells decreases, so countermeasures are taken, such as applying a heat-controlling paint to the back of the mother panel or pasting an aluminum vapor-deposited film. In the present invention, as shown in FIG. 3, by simply dividing an aluminum vapor-deposited sheet at the center of the back surface of the substrate 1, it can be used as an aluminum-deposited film transmission sheet 9 for heat control. Further, in the present invention, since the transmission sheet 9 is provided on both sides or the back surface of the substrate 1, the solar cell element 2 can be mounted on the entire surface of the substrate 10, and the area efficiency can be increased. As a result, a lightweight solar panel can be realized.

Although the present invention is particularly effective in cases where light weight and high efficiency are required, such as solar cells and solar cells for artificial satellites, the gist of the present invention also applies to solar cells and solar cells used on the ground. Of course, this can be applied.
