Cadmium sulfide/copper sulfide photovoltaic devices have shown a great deal of promise for inexpensive power generation. One of the most interesting fabrication techniques proposed for these devices is a chemical spray technique that can be integrated into a float glass substrate plant. This technique, which is being developed by the D.H. Baldwin Company, is a relatively complex process which utilizes chemical solutions sprayed onto hot substrates which can introduce numerous impurities into the active films. This paper discusses the levels of impurities found and their sources. Some of the effects of these impurities, as well as possible methods of eliminating some of them, are discussed.
