ABSTRACT:
Photovoltaic cell comprises thin film cadmium telluride in ohmic contact with a conductive substrate, preferbaly comprising a cadmium surface, through a cadmium-rich layer at the interface with the substrate. The cell further includes a rectifying barrier layer which may be a Schottky barrier. The film is electrodeposited on the substrate surface and the substrate materials and electrodeposition conditions are controlled so as to produce a substantially stoichiometric deposit. Preferably, the film or cell is subsequently treated to enhance its efficiency.
