Concentrator photovoltaics

Concentrator photovoltaics (CPV), also called 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 (MJ) solar cells. In addition, CPV systems often use solar trackers and sometimes a cooling system to further increase their efficiency.
