Abstract
A photovoltaic apparatus includes a second groove so formed as to cut at least an intermediate layer, an insulating member so formed as to cover at least a cut portion of the intermediate layer in the second groove and extend along an upper surface of a second photoelectric conversion layer, and a third groove so formed as to pass through a first photoelectric conversion layer, the intermediate layer, the second photoelectric conversion layer and the insulating member on a region opposite to a first groove with respect to the second groove, wherein the insulating member is so formed as to extend up to at least a region opposite to the first groove with respect to the third groove.

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
- said insulating member is so formed as to extend up to at least said region opposite to said first groove with respect to said third groove.
