尽管付出了很多努力，但用传统无机半导体制成的半导体光伏器件仍然非常昂贵，以至于它们的用途仅限于一些小市场。由于在衬底上直接制造薄器件提供了较低制造成本的前景，特别是对于较大面积的应用，因此目前许多努力都针对使用薄膜半导体来代替硅晶片。1976年，Wronski和Carlson开发了非晶硅太阳能电池，使光伏电池的生产成本更低，其他技术也被开发出来，使更大的设备成为可能，包括多晶硅，碲化镉和铜铟二硒，如本卷其他地方所述。尽管有这些进步，但制造光伏电池的成本对于许多应用仍然高得令人望而却步，特别是当需要大面积时。使这些技术的系统成本相对较高的因素之一是需要在高真空环境中对半导体进行高温处理。这在很大程度上限制了在玻璃基板上的批量加工的制造，并具有相关的成本。
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.
