Chemical spray pyrolysis of cadmium telluride.

Abstract

"Chemical spray pyrolysis is a technique for film growth which is of interest because of its potential for very large scale, inexpensive production of polycrystalline thin film semiconductor materials. Cadmium telluride shows promise as a base material for solar cell applications. Thin films of CdTe have been spray deposited on glass substrates from an aqueous solution containing CdC1₂, Teo₂ and a reducing agent. The films show a zinc blende structure and appear to be intrinsic. Microprobe analysis indicate an excess of Cd, but this is not detectable by X-ray diffraction. The photo absorption studies indicate a direct bandgap of 1.46 ev and an absorption coefficient of the order of 10⁴ cm^-1. The scanning electron microscope pictures indicate grain size of the order of one micron"-- Abstract, p. ii
