Methods for Creating Cadmium Telluride (CdTe) and Related Alloy Film

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A method of creating cadmium telluride films is presented. The method demonstrates heterogeneous nucleation of CdTe directly on a substrate through sequential deposition of aqueous precursor solutions containing cadmium and telluride ions, respectively. The method can include (i) applying a cadmium precursor solution to the substrate to form a cadmium precursor film on the substrate, (ii) applying a telluride precursor solution to the cadmium precursor film. The telluride precursor solution includes Te.sup.2- in solution such that a CdTe film is adherently formed directly on the substrate.
