Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity.
Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material. Materials presently used for photovoltaics include momocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride and copper indium selenide/sulfide.
