Abstract

Methods for forming a conductive oxide layer on a substrate are provided. The method can include sputtering a transparent conductive oxide layer (“TCO layer”) on a substrate from a target (e.g., including cadmium stannate) at a sputtering temperature of about 10° C. to about 100° C. The TCO layer can then be annealed in an anneal temperature comprising cadmium at an annealing temperature of about 500° C. to about 700° C. The method of forming the TCO layer can be used in a method for manufacturing a cadmium telluride based thin film photovoltaic device, further including forming a cadmium sulfide layer over the transparent conductive oxide layer and forming a cadmium telluride layer over the cadmium sulfide layer.
