Concentrator photovoltaics (CPV) (also known as concentrating photovoltaics or concentration photovoltaics) is a photovoltaic technology that generates electricity from sunlight. Unlike conventional photovoltaic systems, it uses lenses or curved mirrors to focus sunlight onto small, highly efficient, multi-junction.
Research into concentrator photovoltaics has taken place since the mid 1970s, initially spurred on by the energy shock from a mideast oil embargo.in Albuquerque, New Mexico was the site for.
According to theory,properties allowto operate more efficiently in concentrated light than they do under a nominal level of . This is because, along with a proportional increase in the generated current, there also occurs a logarithmic.
CPV systems are categorized according to the amount of their solar concentration, measured in "suns" (the square of the ). Low concentration PV (LCPV)Low concentration PV are systems with a solar concentration of.
Modern CPV systems operate most efficiently in highly concentrated sunlight (i.e. concentration levels equivalent to hundreds of suns), as long as the solar cell is kept cool through the use of . Diffuse light, which occurs in cloudy and overcast conditions.
CPV research and development has been pursued in over 20 countries for more than a decade. The annual CPV-x conference series has served as a primary networking and exchange forum between university, government lab, and industry participants. Government agencies.
All CPV systems have aand a concentrating optic. Optical sunlight concentrators for CPV introduce a very specific design problem, with features that make them different from most other optical designs. They have to be efficient, suitable for mass.
The higher , lesser , and added engineering & operational complexities (in comparison to zero and low-concentration PV technologies) make long-life performance a critical demonstration goal for the first generations of CPV.
