THIN FILM SOLAR CELL AND METHOD OF MANUFACTURING THE SAME
First Claim
1. A thin film solar cell comprising:
- a light-transmitting insulating substrate;
a transparent conductive film, a photoelectric conversion layer, and a back-surface electrode layer provided on said light-transmitting insulating substrate; and
a bus bar provided on said back-surface electrode layer,wherein said bus bar is electrically connected with said back-surface electrode layer with a conductive tape interposed whereby said back-surface electrode layer is used as a take-out electrode.

Abstract
A highly reliable thin film solar cell and a method of manufacturing the same are provided to improve bonding strength between a back-surface electrode layer and a bus bar without limiting the kind of metal film of the back-surface electrode layer. The thin film solar cell at least includes a light-transmitting insulating substrate, a transparent conductive film, a photoelectric conversion layer, and a back-surface electrode layer provided on the light-transmitting insulating substrate, and a bus bar provided on the back-surface electrode layer. The bus bar is electrically connected with the back-surface electrode layer with a conductive tape interposed whereby the back-surface electrode layer is used as a take-out electrode. The conductive tape preferably includes a thermosetting resin and a conductive particle. Furthermore, the conductive tape is preferably an anisotropic conductive tape.
