This work is concerned with the spray pyrolysis and electrodeposition of thin CdTe films. Cadmium telluride films have been successfully formed by both chemical spray pyrolysis and electrodeposition. The sprayed films range in thickness from 1 to 4 mu m and have grain sizes of the order of 1 mu m. These films have optical and electrical characteristics which are quite similar to bulk crystalline material. The electrodeposited films range up to 2 mu m and appear to have less crystalline order than the sprayed films. The spray pyrolysis effort has involved the study of spray solutions, substrate temperatures, and spray rates as they relate to rate of film growth, purity of the material and crystal size. We have also investigated impurity doping from solution and the formation of spray pyrolized heterojunctions. The electrodeposition effort has involved the study of electrolytes, types of substrates, ion transport processes and deposition potentials as they relate to film growth, purity and crystal size. We have paid particular attention to the control of stoichiometry, which may be achieved through variations in the deposition parameters. (ERA citation 09:009594)
