【発明の詳細な説明】 この発明は色つき太陽電池に関するものである。[Detailed description of the invention] This invention relates to colored solar cells.

、壊境上好ましくない場合゛もあった。Conventionally, solar cells have been put to practical use in various electrical devices, and the materials used are amorphous silicon and single crystal silicon. However, since the solar cells currently in use are black or a color close to black, they are not aesthetically pleasing, are difficult to use as exterior parts, and have design limitations. Furthermore, when applied outdoors to solar systems, etc., it darkens the surrounding atmosphere, which is sometimes undesirable in terms of environmental destruction.
この発明は、太陽電池に色をつけることによってこうし
た従来技術における欠点全解決するものである。The present invention overcomes all of these drawbacks in the prior art by adding color to the solar cells.
つぎにこの発明の実施例について説明する。Next, embodiments of the invention will be described.

乱層2によって選択散乱される波長の光も纒択散乱層に
よって完全に遮へいされることなく、半分近くは透過す

なくなる早はない。しかし、発電効率を落さないために
はずらした方がよい。たとえは青色系の選択散乱層2を
用いると、その光透過率は第2図で曲線Aで示される。In FIG. 1, a selective scattering layer 2 is arranged on the it+ side of a solar cell 1. The solar cells 1 currently in practical use include amorphous silicon and straddle single crystal silicon, and when these are used, the duration that contributes to the power generation of the solar cells is as shown in the second figure. Selective scattering layer 2
As the liquid crystal, cholesterink liquid crystal, chiral nemateink liquid crystal, a mixture of these liquid crystals, a microcapsule of these liquid crystals, and a cholesterink polymer sheet are used. The selective scattering layer 2 scatters light of a specific wavelength in the visible range, but it
It is better to shift the wavelength away from the wavelength that contributes to power generation. The light of the wavelength that is selectively scattered by the selective scattering layer 2 is not completely blocked by the selective scattering layer, and nearly half of it is transmitted, so no matter which color selective scattering layer in the visible range is used, it will quickly stop generating electricity. There isn't. However, it is better to shift it so as not to reduce power generation efficiency. For example, if a blue selective scattering layer 2 is used, its light transmittance is shown by curve A in FIG.
したがって、この場合は太陽電池1としてアモルファス
シリコンを用いても単結晶シリコンを用いてもほとんど
発電効率を落さずにすむ。Therefore, in this case, whether amorphous silicon or single crystal silicon is used as the solar cell 1, the power generation efficiency hardly decreases.
赤色系の選択散乱層2を用いた場合もほぼ同様のことが
言える。Almost the same thing can be said when using the red selective scattering layer 2.
なお選択散乱層2は太陽電池1の全面に配置しなければ
ならないものではなく、帯状などの模様や、あるいは文
字や絵のパターンなどに設けてもよい。そうすると黒い
地の上にカラーで図形などが表示され面白味のあるもの
となる。Note that the selective scattering layer 2 does not have to be arranged on the entire surface of the solar cell 1, but may be provided in a pattern such as a band shape, or a pattern of letters or pictures. Then, the figures will be displayed in color on a black background, making it more interesting.
また太陽電池の上に色の異なる複数の選択散乱層を設け
れば多色カラーとすることができる。Furthermore, if a plurality of selective scattering layers of different colors are provided on the solar cell, it can be made multicolored.
さらに太陽電池の上に選択散乱波長の異なる複数の選択
散乱層を重ねて設けて色調をコントロールすることもで
きる。Furthermore, the color tone can be controlled by stacking a plurality of selective scattering layers having different selective scattering wavelengths on the solar cell.
なお、4択散乱層に温度によって色が変化するコレステ
リンク液晶を用いれば、より変化をもたせることができ
、また温度計としても使うことが可能となる。Furthermore, if a cholesterin liquid crystal whose color changes depending on the temperature is used for the four-selective scattering layer, it is possible to provide more variation, and it also becomes possible to use it as a thermometer.
上述の構成よりなる本発明の色つき太陽電池は、カラフ
