ABSTRACT:
A photovoltaic device including a current collection element and a method of making same. The photovoltaic device includes a substrate, a conductive layer, an active photovoltaic material, a transparent electrode and a current collection element. The current collection element includes a transparent support and one or more conductive wires integrated therewith. The conductive wires are in electrical communication with the transparent electrode. Current generated by the active photovoltaic material passes to the transparent electrode. The current collection element facilitates delivery of current passing through the transparent electrode to leads that deliver the current to an external load. The method includes placing a pre-fabricated current collection element in direct contact with the transparent electrode of the photovoltaic device. The time and expense of assembling the conductive wires during fabrication of the photovoltaic device is thereby avoided and higher manufacturing speeds are achieved.
