What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels.

Solar cells depend on a phenomenon known as the photovoltaic effect, discovered by French physicist Alexandre Edmond Becquerel (1820-1891). It is related to the photoelectric effect, a phenomenon by which electrons are ejected from a conducting material when light shines on it.
