METHOD OF PRODUCING TWO OR MORE THIN-FILM-BASED INTERCONNECTED PHOTOVOLTAIC CELLS

摘要

The present invention is directed to a method of producing two or more thin-film-based interconnected photovoltaic cells (100) comprising the steps of: a) providing a photovoltaic article comprising: a flexible conductive substrate, at least one photoelectrically active layer, and a top transparent conducting layer; b) forming one or more first channels (140) through the flexible conductive substrate to expose a portion of the photoelectrical]?—active layer; e) applying an insulating segment to the conductive substrate and spanning the one or more first-channel; d) forming one or more second channels off set from the one or more first channels—‘through—the photoelectrically active layer to expose a conductive surface of the flexible conductive substrate; I) forming one or more third channels (170) off set from both the first channels and the second channels, through the top transparent conducting layer and to the photoelectrically active layer: and g) applying an electrically conductive material (180) above the top transparent conducting layer and in the second channels, thus producing two or more Interconnected photovoltaic cells.
