Cadmium telluride films have been deposited by the direct combination of the elements on the surface of heated substrates in hydrogen. The resistivity of p-type films was controlled by using a cadmium-deficient reaction mixture, and adding a dopant to a nearly stoichiometric reaction mixture. Heterojunction solar cells were prepared from p-type cadmium telluride films by using cadmium oxide, cadmium sulfide, tin-doped indium oxide, and zinc oxide, deposited by ionbeam sputtering, spray pyrolysis, or vacuum evaporation, as the window material. Thus far, n-ITO/p-CdTe solar cells have the highest AM1 efficiency, 8.1% for cells of 1 cm/sup 2/ area. All heterojunction cells exhibit some degradation under continuous illumination, which may be minimized by passivation.
