差は、約200℃にも達する。 Substrates used in conventional solar panels have the main purpose of holding solar cells, and either do not have any notches for thermal control, or even if they do, the area of the notches is always constant. It was hot. FIG. 1 shows a conventional substrate 1 in which a notch 3 is provided on the back surface (the surface on which solar cells are not mounted) of the plate 2. As shown in FIG. This figure shows the back side of the substrate, and the solar cell mounting surface is provided on the opposite side. The notch is the shaded area.
4 is a honeycomb core. FIG. 2 shows an example of the relationship between the solar cell temperature on the substrate and the ratio (percentage) between the total area of the back plate of the substrate and the opening area of the notch. By selecting the size of the opening area of the notch, it is possible to set the temperature of the solar cell to an appropriate value. However, even in this case, the difference in temperature between sunshine and shade is always almost constant. For example, in the case of a paddle-shaped geostationary satellite, the temperature difference between solar cells during sunlight and shade can reach approximately 200 degrees Celsius.

プリングが大形化するなどの欠点が生じていた。 Generally, the lower the temperature of a solar cell, the higher the efficiency of converting it into electrical energy. Therefore, in order to obtain more generated power, it is desirable to set the opening area of the notch to about 50% of the total area of the substrate back plate (see Figure 2). but,
In this case, in the shade, the temperature of the solar cells and the substrate (the temperature of the substrate is almost equal to the temperature of the solar cells) becomes too low. If the temperature of the substrate becomes too low, the performance of electrical components normally mounted on the substrate (diodes to prevent reverse flow of solar cell output, resistors and transistors to dissipate excess power in the event of overpowering, etc.) will deteriorate. The maintenance temperature range will be exceeded. For this reason, in the past, in order to protect the electrical components, the temperature of the substrate was set higher, or the electrical components were mounted inside the body of a flying object such as a satellite, knowing that the conversion efficiency of solar cells would deteriorate. was. Note that when electrical components are mounted inside the body of a flying object, the number of electrical wiring between the solar cell array and the body of the flying object increases, and the slip rings for transmitting power and electrical signals become larger. There were some shortcomings.

Figure 3 is a back view when the opening area of the notch 3 of the substrate 9 is approximately 50% of the total area of the back plate, Figure 4 is its cross-sectional view, and Figure 5 is the opening area of the notch being 50% of the total area of the back plate. The rear view and FIG. 6 are cross-sectional views when the width is narrower. In the figure, 5 is the solar cell element, 6 is the cover glass, 7 is the interconnector, 8 is the adhesive that fixes the solar cell element 5 to the substrate 9, 10 is the surface plate of the substrate 9, and 11 is the substrate.

Reference numerals 2 and 13 are back plates of the substrate, which are superimposed on each other and are slidable relative to each other. Further, the arrows in the figure indicate absorption, conduction, and radiation of heat. Arrow a indicates heat absorption from sunlight, etc., arrow b indicates heat conduction from the cover glass 6 to the substrate surface plate 10, and c indicates heat conduction from the substrate surface plate. 10 to the honeycomb core 11; d is the heat conduction from the honeycomb core 11 to the substrate back plates 12 and 13;
e is heat radiation from the cover glass 6 to space, f
g means heat radiation from the substrate front plate 10 to outer space, g means heat radiation from the honeycomb core 11 to outer space, and h means heat radiation from the substrate back plates 12 and 13 to outer space. When the opening area of the notch 3 is set to about 50%, the temperature of the solar cell becomes the lowest and the efficiency of converting light energy into electrical energy becomes the highest, as shown in FIG. Next, when the opening area of the notch is made smaller than 50%, heat radiation (f,
g) decreases and the solar cell temperature and substrate temperature increase. Utilizing the above characteristics,
The opening area of the notch is set so that the temperature of the solar cell is low when the flying object is in sunlight, and the opening area of the notch is set so that the temperature of the substrate (approximately equal to the temperature of the solar cell) is high when it is in the shade. If you vary
The temperature difference between sunshine and shade can be narrowed.
Therefore, the solar cell can be operated with high efficiency during sunlight while maintaining the performance maintenance temperature range of the electrical components mounted on the substrate during shade. The relationship between the notch area and solar cell temperature depends on the material (thermal characteristics) of the front and back plates of the substrate.
It can be adjusted by selecting.

等の利点がある。 As explained above, the solar cell panel according to the present invention maintains the temperature of the substrate within the temperature range that maintains the performance of the electrical components mounted thereon when the flying object is in the shade, and lowers the temperature of the solar cell when it is sunny. Can be done. Therefore, the conversion efficiency of solar cells into electrical energy is increased, and more generated power can be obtained.In addition, resistors and transistors are used to consume excess power in the event of overpowering, and the backflow of the solar cell output is prevented. Since electric components such as diodes for prevention can be attached to the substrate, there are advantages such as the ability to reduce wiring for power and signal transmission between the flying object and the substrate.
