Primestar Solar, Arvada, Colo., has been assigned a patent (8,252,618) developed by Patrick Lynch O'Keefe, Loveland, Colo., for "methods of manufacturing cadmium telluride thin film photovoltaic devices." The abstract of the patent published by the U.S. Patent and Trademark Office states: "Methods for manufacturing a cadmium telluride based thin film photovoltaic device are generally disclosed. A resistive transparent layer can be sputtered on a transparent conductive oxide layer from a metal alloy target in a sputtering atmosphere of argon and oxygen that includes argon from about 5% to about 40%. A cadmium sulfide layer can then be formed on the resistive transparent layer. A cadmium telluride layer can be formed on the cadmium sulfide layer; and a back contact layer can be formed on the cadmium telluride layer. The sputtering can be accomplished within a sputtering chamber."
