Title: Solar cell interconnection by discrete conductive regions

Abstract

A thin film solar module is described comprising: first electrode pads on a substrate, each first electrode pad comprising a conductive metal oxide film and a metallic portion in electrical contact therewith; at least one semiconductive layer deposited over the first electrode pads to establish a photovoltaic region corresponding to each first electrode pad; second electrode pads deposited onto the semiconductive layer, each second electrode pad overlying one of the photovoltaic regions and overlapping the first electrode pad of an adjacent photovoltaic region over a preselected area which includes the metallic portion of the first electrode pad; and localized conductive paths extending through the semiconductive layer from each second electrode pad to the metallic portion of the first electrode pad that it overlaps to connect at least two of the photovoltaic regions in series, the conductive paths comprising discrete conductive regions spaced apart from each other within the plane of the module.
