A photovoltaic device includes a semi-continuous metal layer having an uneven surface, which is not uniform, formed on a substrate, a reflective continuous metal layer having a substantially uniform thickness formed to cover the semi-continuous metal layer, a semiconductor film for photoelectric conversion formed on the reflective continuous metal layer, and a transparent electrode formed on the semiconductor film.

Photovoltaic device with porous metal layer

An amorphous semiconductor solar cell includes an i type layer which is an at least partially alloyed, substantially intrinsic semiconductor, an n type layer formed on one side of the i type layer, and a p type layer formed n the other side of the i type layer, and the i type layer has its energy bandgap varied in a thickness direction to have a bandgap larger than the bandgap of the p type layer in the vicinity of the interface with the p type layer.
