Abstract

Abstract A photoelectric converter has a photoelectric conversion means formed on a substrate (20). The photoelectric conversion means includes at least, a first electrode (31), a hydrogenated amorphous silicon layer (32) formed on said first electrode and a second electrode consisting of a transparent conductive layer (38) formed on the hydrogenated amorphous silicon layer. The improvement consists in that the transparent conductive layer (38) is a layer made of In 2 O 3 or a solid solution of In 2 O 3 and Sn0 2 and has a thickness in the range 300A to 2000A. This transparent conductive layer is free from the problem of peeling, and has an electric conductivity sufficiently high to make it useful in practice.
