Process for producing cadmium sulfide on a cadmium telluride surface

Patent Levi, Dean H [Lakewood, CO]; Nelson, Art J [Longmont, CO]; Ahrenkiel, Richard K [Lakewood, CO]

A process for producing a layer of cadmium sulfide on a cadmium telluride surface to be employed in a photovoltaic device. The process comprises providing a cadmium telluride surface which is exposed to a hydrogen sulfide plasma at an exposure flow rate, an exposure time and an exposure temperature sufficient to permit reaction between the hydrogen sulfide and cadmium telluride to thereby form a cadmium sulfide layer on the cadmium telluride surface and accomplish passivation. In addition to passivation, a heterojunction at the interface of the cadmium sulfide and the cadmium telluride can be formed when the layer of cadmiummore » « less
