摘要： The present invention provides a solar cell whose external color can be adjusted so that redness is suppressed. In the case where a photoelectric conversion layer contains amorphous silicon, an optical absorption layer is provided between the photoelectric conversion layer and a reflecting electrode layer. The optical absorption layer has a light absorbing property mainly in a long wavelength range, while the photoelectric conversion layer (amorphous silicon) has a selective light absorbing property mainly in a short/medium wavelength range. Incident light (solar light) passed through the photoelectric conversion layer further passes through the optical absorption layer and, after that, is reflected by the reflecting electrode layer. That is, remaining light of the incident light absorbed by the optical absorption layer and the photoelectric conversion layer is reflected by the reflecting electrode layer. Consequently, redness of the reflection light can be suppressed more than in the case where the optical absorption layer is not provided between the photoelectric conversion layer and the reflecting electrode layer.
摘要翻译：本发明提供一种太阳能电池，其外部颜色可以被调整以抑制发红。在光电转换层包含非晶硅的情况下，在光电转换层和反射电极层之间设置光吸收层。光吸收层主要在长波长范围内具有吸光性，而光电转换层（非晶硅）主要在短/中等波长范围内具有选择性的光吸收特性。通过光电转换层的入射光（太阳光）进一步通过光吸收层，之后被反射电极层反射。也就是说，由光吸收层和光电转换层吸收的入射光的剩余光被反射电极层反射。因此，与光电转换层和反射电极层之间没有设置光吸收层的情况相比，能够抑制反射光的发红。
