Abstract:
1. A photovoltaic apparatus comprising: a substrate having an insulating surface; a first substrate electrode and a second substrate electrode formed on said insulating surface of said substrate and separated through a first groove; a first photoelectric conversion layer so formed as to cover said first substrate electrode and said second substrate electrode; a second photoelectric conversion layer formed on a surface of said first photoelectric conversion layer through a conductive intermediate layer; a second groove so formed as to cut at least said intermediate layer on a region of said first substrate electrode; an insulating member so formed as to cover at least a cut portion of said intermediate layer in said second groove and extend along an upper surface of said second photoelectric conversion layer; a third groove so formed as to pass through said first photoelectric conversion layer, said intermediate layer, said second photoelectric conversion layer and said insulating member on a region opposite to said first groove with respect to said second groove and expose a surface of said first substrate electrode; a back electrode so formed as to electrically connecting said first substrate electrode and said second photoelectric conversion layer on a side of said second substrate electrode through said third groove; and a fourth groove for electrically separating at least said back electrode into a first back electrode and a second back electrode corresponding to said first substrate electrode and said second substrate electrode respectively on a region opposite to said first groove with respect to said third groove, wherein
