Patent number: 5536333Abstract: A process and apparatus (70) for making a large area photovoltaic device (22) that is capable of generating low cost electrical power. The apparatus (70) for performing the process includes an enclosure (126) providing a controlled environment in which an oven (156) is located. At least one and preferably a plurality of deposition stations (74,76,78) provide heated vapors of semiconductor material within the oven (156) for continuous elevated temperature deposition of semiconductor material on a sheet substrate (24) including a glass sheet (26) conveyed within the oven. The sheet substrate (24) is conveyed on a roller conveyor (184) within the oven (156) and the semiconductor material whose main layer (82) is cadmium telluride is deposited on an upwardly facing surface (28) of the substrate by each deposition station from a location within the oven above the roller conveyor.Type: GrantFiled: August 15, 1995Date of Patent: July 16, 1996Assignee: Solar Cells, Inc.Inventors: James B. Foote, Steven A. F. Kaake, Peter V. Meyers, James F. Nolan

Patent number: 4345107Abstract: 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.Type: GrantFiled: December 15, 1980Date of Patent: August 17, 1982Assignee: Ametek, Inc.Inventors: Gabor F.
