Abstract
A photovoltaic device of this invention has a semiconductor layer for generating a photovoltaic power and a collector electrode formed on the semiconductor layer to collect the power generated by the semiconductor layer. A conductive layer containing a conductive powder is formed on at least one side of the collector electrode closer to the semiconductor layer, and a metal layer is formed on the side away from the semiconductor layer. The metal layer covers the surface of the conductive layer away from the semiconductor layer.
