An unusual processing scheme has been developed for preparing single- phase cadmium stannate (Cd{sub 2}SnO{sub 4} or CTO) films. Cd{sub 2}SnO{sub 4} transparent conducting oxide (TCO) films have several significant advantages over conventional TCOs when applied to CdS/CdTe thin-film devices. They are more conductive, more transparent, have lower surface roughness, are patternable, and are exceptionally stable. Cd{sub 2}SnO{sub 4}-based CdS/CdTe polycrystalline thin-film solar cells with efficiencies of 14% have been fabricated. Preliminary cell results have demonstrated that device performance can be enhanced by replacing the SnO{sub 2} layer with a Cd{sub 2}SnO{sub 4} TCO film.
