本発明は太陽電池電源装置に関し、特に太陽電池セル本
体に導電性コーティングを塗布して熱輻射率を向上した
太陽電池電源装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solar cell power supply device, and more particularly to a solar cell power supply device in which a conductive coating is applied to a solar cell body to improve thermal emissivity.
従来の太陽電池電源装置は一部に帯電防止用として導電

性を良くするために導電性コーティングの厚さを最適に
選択することができなかった。Some conventional solar cell power supply devices use a cover glass coated with a conductive coating to prevent static electricity, but the thickness of the conductive coating is determined by the required value of surface resistance J, that is, the required conductivity. Therefore, it was not possible to optimally select the thickness of the conductive coating to improve the heat radiation properties.

電池電源装置や衛星搭載装置の動作可能範囲を逸脱して
しまう等の欠点がある。In the conventional solar cell power supply device described above, the thermal characteristics of the solar cell panel cannot be appropriately selected depending on the thickness of the conductive coating, so heat must be dissipated at a location other than the solar cell panel. Therefore, there is a drawback that more space is required to mount the heat control material, the mounting area of the solar cell panel is reduced, and the generated power is reduced. On the other hand, if a sufficient mounting area for the solar panel is secured, the heat control space will be reduced, and if the temperature of the solar panel etc. becomes high, the operating efficiency of the solar cell will decrease and the generated power will decrease. . Furthermore, if the temperature drops to low temperatures, there are drawbacks such as the possibility that the operating range of the solar battery power supply device and satellite-mounted equipment will be exceeded.

It is composed of a conductive coating 4, a glass base material 5, and an adhesive 6. Here, by changing the film thickness of the conductive coating 4, the emissivity ε, which is one of the thermal characteristics, reaches a maximum value and does not change when the film thickness is 600 angstroms or less, as shown in the characteristic diagram in Figure 2. rate is obtained.

力を向上させることができる。Next, FIG. 3 shows an external view of an artificial satellite to which this embodiment is applied. The artificial satellite shown in FIG. 3 uses a polyhedral body-mounted solar cell panel 7 with a cover glass. Furthermore, due to the heat generation amount of the onboard equipment and the shading rate due to the orbit of the artificial satellite, the heat radiation area 8 other than the solar cell panel 7 with a cover glass is buffed with aluminum having a high emissivity ε. FIG. 4 is a characteristic diagram showing the relationship between the thermal characteristics α/ε of the surface of the solar cell panel and the temperature of the solar cell panel. Here, the thermal characteristics α/ε are determined by the sum of the thermal characteristics of the solar cell panel 7, which occupies most of the surface, and the aluminum buffing of the heat radiation region 8. Therefore, by making the solar cell panel 7 in which the cover glass of the solar cell is coated with a conductive coating, the heat radiation area 8 can be made smaller.
It is possible to further increase the ratio of the pasting area and improve the generated power.
