Abstract:
1. An apparatus for use as a thin-film photovoltaic cell comprising: a substrate having a first side and a second side; a photoactive layer deposited onto at least part of said first side of said substrate; a first insulator layer deposited onto at least part of said first side of said substrate; three or more weld contact points defined by said photoactive layer on said first side, said substrate exposed at the weld contact points; a grid deposited on said photoactive layer and on said first insulator layer, such that the substrate remains exposed at said weld contact points; a second insulator layer deposited on at least a portion of said grid and on said second side of said substrate such that the substrate remains exposed opposite said weld contact points; and at least one first weld contact deposited onto said grid covering said first insulator layer; wherein said first weld contact facilitates attachment to a second cell.
