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

摘要

The present invention is premised upon a method of producing two or more thin-film-based interconnected photovoltaic cells comprising the steps of: a) providing a photovoltaic article comprising: a flexible conductive substrate, at least on photo-electrically active layer, a top transparent conducting layer, and a carrier structure disposed above the tap transparent layer; b) forming one or more first channels through the layers of the photovoltaic article; c) applying an insulating layer to the conductive substrate and spanning the one or more first channel; d) removing the carrier structure; e) forming an addition to the one or more first channels through the insulating layer; f) forming one or more second channels off set from the one or mom first channels through the insulating layer to expose a conductive surface of the flexible conductive substrate; g) applying a first electrically conductive material to the conductive surface of the flexible conductive substrate via the one or more; second channels; h) applying an electrically conductive film to the first insulating layer, wherein the film is hi electrical communication with the flexible conductive substrate via the first electrically conductive material; J) applying a second electrically conductive material above the top transparent conducting layer and through the one or more first channels, electrically connecting the layers of the photovoltaic article from step b to the electrically conductive
