Photovoltaics (or PV) is the generation of electric currents from electromagnetic radiation using the photovoltaic effect (compare solar-thermal electricity).

A PV cell is the basic unit of a PV array. It is usually made of a silicon substrate coated with a thin film. These are mounted together with supporting structure to form PV panel.[1]
