本発明は太陽電池素子をガラス繊維強化プラス
チツクス（以下、FRPと称する）中に埋設した
太陽電池装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar cell device in which a solar cell element is embedded in glass fiber reinforced plastics (hereinafter referred to as FRP).
FRP中に太陽電池素子を一体に組込み成型し
た太陽電池装置（以下、FRP封入太陽電池装置
と称する）は、安価で大量生産に適し、かつ破損
しにくいという長所を有するため、太陽電池の用
途を大幅に広げるものとして期待されている。 Solar cell devices in which solar cell elements are integrally molded into FRP (hereinafter referred to as FRP-encapsulated solar cell devices) have the advantages of being inexpensive, suitable for mass production, and hard to break, so they are widely used in solar cell applications. It is expected that this will expand significantly.
しかしながら、このFRP封入太陽電池装置
は、長期の屋外使用によりFRP自体の光線透過
率が低下し、結果的に太陽電池の出力が低下して
しまうという欠点があつた。 However, this FRP-encapsulated solar cell device has a drawback in that the light transmittance of the FRP itself decreases due to long-term outdoor use, resulting in a decrease in the output of the solar cell.
そこで本発明者はFRPの光線透過率低下の原
因を調査した結果、水分がこの低下に重大な影響
をおよぼしていることが判明した。すなわち、
FRPを構成するガラス繊維基材の末端部分から
水分が侵入し、この水分がガラス繊維基材に施さ
れた表面処理材を劣下させ、遂にはガラス繊維基
材とFRPを構成する樹脂との剥離を招き、FRP
の光線透過率を低下させているわけである。 The inventor investigated the cause of the decrease in light transmittance of FRP and found that moisture had a significant effect on this decrease. That is,
Moisture enters from the end of the glass fiber base material that makes up the FRP, and this water deteriorates the surface treatment material applied to the glass fiber base material, and eventually the glass fiber base material and the resin that makes up the FRP deteriorate. FRP may cause peeling.
This reduces the light transmittance of the material.

There are roving cloths, continuous strand mats, etc., but these glass fibers are
When used as an FRP material, the surface of the glass fiber is treated with a surface treatment agent, such as chromium treatment with an organic chromic acid compound or silane treatment with an organic silane compound, to improve adhesion with the FRP constituent resin. ing. However, even if these surface treatments are performed, water that enters from the end portion of the glass fiber in a capillary manner due to long-term use deteriorates the surface treatment agent, resulting in a decrease in the light transmittance of the FRP.
上記の欠点に鑑み、本発明者は末端部分の少な

を得ることができた。 In view of the above-mentioned drawbacks, the present inventors were able to obtain an FRP-encapsulated solar cell device with less decrease in light transmittance due to moisture by using glass fibers with fewer end portions.
以下、第１図に示す本発明の１実施例の断面図

After arranging two continuous strand mats 4 as glass fibers with few end portions on both the upper and lower surfaces of this solar cell element 2 (surface coating resin 3), resin 5 is poured in, and the outermost layer is coated with a surface protective coating 6. cover to produce a solar cell device according to the present invention. In addition to the above-mentioned continuous strand mat, glass fibers with a small number of ends include glass cloth and roving cloth, and these glass fibers can be used alone or in combination as long as they have a small number of ends. Can be used for inventions.

る。 FIGS. 2 and 3 show how the solar cell device according to the present invention deteriorates compared to a solar cell using glass fiber with many end portions (hereinafter referred to as a conventional solar cell device). Figures 2 and 3 are JIS-
A temperature/humidity cycle test according to C-5024 (temperature/humidity cycle test) was conducted on a solar cell element according to the present invention (each figure A) and a conventional solar cell element (each figure B). The actual temperature and humidity cycle was a maximum temperature of 70℃ (95%RH) and a minimum temperature of -20℃.
One cycle (6 hours) consists of holding each temperature (humidity) for 1.5 hours and shifting for 1.5 hours each. Second
The figure shows the change in total light transmittance when the initial value of total light transmittance is 100%, and Figure 3 shows the change in yellowing index (YI) value based on JIS-K-7103. Further, in the solar cell device A of the present invention, glass cloth is used as the glass fiber, and in the conventional solar cell device B, a chopped strand mat is used.

用）には何ら変化は見られなかつた。 As is clear from FIG. 2, the transmittance of the conventional solar cell device showed a sharp drop after the 100th cycle, and after the 200th cycle it decreased to a value that made it unusable. On the other hand, the solar cell device of the present invention showed almost no deterioration up to 250 cycles and was extremely effective. In addition, as shown in Figure 3, the degree of yellowing also decreases.
The conventional solar cell device suddenly turned yellow after 100 cycles, but the solar cell device according to the present invention showed extremely slow change. In parallel with this temperature/humidity cycle test, we actually conducted an outdoor exposure test, and found that glass fibers were exposed in the conventional solar cell device (using chopped strand pine) after one year of outdoor exposure. No change was observed in the solar cell device of the present invention (using glass cloth).
以上のように、本発明の末端部分の少ないガラ

FRP劣下が小さく、したがつて高出力の太陽電
池装置を提供できる。 As mentioned above, since the glass fiber of the present invention with fewer end portions is used, it can be used for a long period of time.
FRP degradation is small, and therefore a high output solar cell device can be provided.
