H01L 31/18 H01L 31/0224
US Classification:
136256, 438 98, 257E31126
Abstract:
Methods for forming a back contact on a thin film photovoltaic device are provided. The method can include: applying a conductive paste onto a surface defined by a p-type absorber layer (of cadmium telluride) of a p-n junction; and, curing the conductive paste to form a conductive coating on the surface such that during curing an acid from the conductive paste reacts to enrich the surface with tellurium but is substantially consumed during curing. The conductive paste can comprises a conductive material, an optional solvent system, and a binder. Thin film photovoltaic devices are also provided, such as those that have a conductive coating that is substantially free from an acid.
Back Contact Paste With Te Enrichment And Copper Doping Control In Thin Film Photovoltaic Devices

US Classification:
438 95
Abstract:
Methods for forming a back contact on a thin film photovoltaic device are provided that include applying a conductive paste onto a surface defined by a p-type absorber layer (e.g., comprising cadmium telluride) of a p-n junction and curing the conductive paste to form a conductive coating on the surface defined by a p-type absorber layer of the p-n junction. The conductive paste can include a conductive material, a solvent system, and a binder such that during curing an acid from the conductive paste reacts to enrich the surface with tellurium while copper is deposited onto the Te enriched surface. The acid is then substantially consumed during curing.
