CdTe Schottky barrier photovoltaic cell

摘要

Photovoltaic cell comprises thin film cadmium telluride in ohmic contact with a smooth conductive substrate, preferably comprising a cadmium surface, through a cadmium-rich layer at the interface with the substrate, the cell further including a rectifying barrier layer. Preferably, the film is electrodeposited on the substrate surface with specific materials and process conditions. Preferably also, the film or cell is subsequently treated to enhance its barrier layer interface function.
