Abstract
A method for forming a thin film photovoltaic device may include providing a transparent substrate and forming a multi layered structure including at least a thin layer of indium material, copper material, and another layer of indium. A heat treatment may be performed that consumes substantially all of the thin layer of indium material into a portion of a copper indium disulfide alloy material. The method causes formation of a copper sulfide material overlying the copper indium disulfide alloy material during at least the thermal treatment process.
