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 isolated from each other by a first groove; a first photoelectric conversion portion so formed as to cover said first substrate electrode and said second substrate electrode; a second photoelectric conversion portion formed on the surface of said first photoelectric conversion portion through a conductive intermediate layer; a first back electrode and a second back electrode, formed on the surface of said second photoelectric conversion portion, corresponding to said first substrate electrode and said second substrate electrode respectively wherein the lower surface of the back electrode directly contacts the second photovoltaic layer; a second groove for electrically isolating said first back electrode and said second back electrode from each other; a third groove formed on a region located between said first groove and said second groove to cut at least said intermediate layer from a side of said second back electrode; a first insulating member embedded in said third groove to cover at least a cut portion of said intermediate layer; and a conductive member electrically connected to said first substrate electrode on a region located between said second groove and said third groove and electrically connected to an upper surface of said second back electrode across said third groove and an upper surface of said first insulating member, wherein said conductive member is provided separately from said second back electrode.
