ABSTRACT:
The photovoltaic device of this invention has a p-type layer of oxides of the platinum group between a transparent electrode layer texturized at the side opposite the light incident surface and a semiconductive layer having a semiconductor junction and including a p-type layer at the light incident side thereof.
With such a construction, the optical path length of an incident ray is increased, thereby improving the photoelectric conversion efficiency. Also, since the p-type semiconductive layer contacts the p-type layer of oxides of the platinum group, imperfections in the semiconductor junction can be reduced. Accordingly, with a photovoltaic device of this invention, the peak value of the photoelectric conversion efficiency can be increased and also the manufacturing yield can be remarkably increased.
