Abstract

In one aspect of the present invention, a method is provided. The method includes disposing a substantially amorphous cadmium tin oxide layer on a support; and thermally processing the substantially amorphous cadmium tin oxide layer in an atmosphere substantially free of cadmium from an external source to form a transparent layer, wherein the transparent layer has an electrical resistivity less than about 2×10−4 Ohm-cm. Method of making a photovoltaic device is also provided.
