Despite much effort, semiconductor photovoltaic devices made with traditional inorganic semiconductors have remained sufficiently expensive that their uses are confined to a number of niches. Much effort is currently directed towards the use of thin-film semiconductors, in place of silicon wafers, since the direct fabrication of thin devices on substrates offers the prospect of lower manufacturing costs, particularly for larger area applications. The development of amorphous silicon solar cells in 1976 by Wronski and Carlson had the potential of making photovoltaic cells cheaper to produce, and other techniques have been developed to make larger devices possible, including polycrystalline silicon, cadmium telluride, and copper indium diselenide, as described elsewhere in this volume. Despite these advances, the cost of fabricating photovoltaic cells remains prohibitively high for many applications, particularly when large areas are required. One of the factors that keeps system costs relatively high for these technologies is the requirement for high-temperature processing of the semiconductor in a high vacuum environment. This largely restricts fabrication to batch processing onto glass substrates, with associated costs.
