ABSTRACT:
A process for producing a photoelectric conversion device comprising a substrate having a conductive surface, a semiconductor layer disposed on said conductive surface of said substrate, a transparent and conductive layer disposed on said semiconductor layer and a collecting electrode disposed on said transparent and conductive layer, wherein one or more defective portions formed at the semiconductor layer are repaired by means of electrolytic treatment using an electrolytic solution containing a material capable of providing an insulating material, wherein the conductive surface of the substrate is made an electrode, to thereby deposit an insulating material selectively at each of the defective portions.
