Abstract:
A solar cell device in which a transparent oxide electrode is provided on an insulating substrate, a p-type semiconductor layer, an intrinsic semiconductor layer, and an n-type semiconductor layer are provided over the transparent oxide electrode in that order, and a metal electrode is provided on the n-type semiconductor layer,wherein said transparent oxide electrode is provided by being patterned by dry etching and side faces thereof which are not provided with said p-type semiconductor layer are formed in a tapered shape gradually inclined outward from the top end thereof toward said insulating substrate,wherein said transparent oxide electrode is provided with a surface treatment layer formed by performing oxidative plasma treatment on the entire surface thereof including the side faces which are not provided with said p-type semiconductor layer and said surface treatment layer is between said transparent oxide electrode and said p-type semiconductor layer,wherein a silicon nitride film is provided between the surface treatment layer and said p-type semiconductor layer, andwherein the side faces of said transparent oxide electrode which are not provided with a p-type semiconductor layer are formed to be capable of being connected with an interconnection code via the surface treatment layer.
