Photovolataics: the semiconductor revolution comes to solar

If there is a dream solar technology it is probably photovoltaics solar cells. These devices convert sunlight to electricity directly, bypassing thermodynamic cycles and mechanical generators altogether. They have no moving parts and are consequently quiet, extremely reliable. and easy to operate. Photovoltaic cells are a space age electronic marvel, at once the most sophisticated solar technology and the simplest, most environmentally benign source of electricity yet conceived.
