Method and making group IIB metal - telluride films and solar cells
A technique is disclosed for forming thin films of group IIB metal-telluride, such as Cd[sub x]Zn[sub 1[minus]x]Te (0 [<=] x [<=] 1), on a substrate which comprises depositing Te and at least one of the elements of Cd, Zn, and Hg onto a substrate and then heating the elements to form the telluride. A technique is also provided for doping this material by chemically forming a thin layer of a dopant on the surface of the unreacted elements and then heating the elements along with the layer of dopant. A method is disclosed of fabricating a thin film photovoltaic cell which comprises depositing Te and at least one of the elements of Cd, Zn, and Hg onto a substrate which contains on its surface a semiconductor film and then heating the elements in the presence of a halide of the Group IIB metals, causing the formation of solar cell grade Group IIB metal-telluride film and also causing the formation of a rectifying junction, in situ, between the semiconductor film on the substrate and the Group IIB metal-telluride layer which has been formed. 5 figs.
