CONSTITUTION:An amorphous Si layer having a semiconductor junction has sensitivity for a short wavelength of mainly 0.4-0.7mum in solar light and converts the short wavelength into electrical energy. Amorphous Ge having a semiconductor junction converts a wavelength light of 0.65-1.1mum in solar light passed the amorphous Si layer into electrical energy. Therefore, the short wavelength light is effectively absorbed into the amorphous Si layer and the long wavelength light is effectively absorbed by the amorphous Ge layer and both of them become photocurrent. Therefore, the characteristics of photosensitivity will remarkably be improved.,下面是Amorphous thin solar cell专利的具体信息内容。
