Concentrating Photovoltaic

December 3, 2009 Leave a comment Go to comments

Concentrating photovoltaic (CPV) uses lenses (Fresnel lens for example) or variations of mirrors to focus or enhance the sun’s light on a photovoltaic solar panel or cell. This technology includes both a low-concentration approach, which increases the sun’s magnification by less than 5 “suns,” and high concentration approach, which can increase the magnification by hundreds of suns.  High-concentration CPV uses focusing lenses to concentrate the sun’s rays on a single, high efficiency solar cell that is very small, on the order of 1-centimeter square.
