Photovoltaic semiconductors convert light directly to electricity. Individual photovoltaic cells may be used for detecting and measuring light, and arrays of the cells can produce useful electric power. Considerable investment has gone into improving the efficiency of their power generation, so they can move from expensive and specialized applications to becoming a significant renewable energy source.
