Solar Photovoltaic Technology Basics

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 effect

The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy.The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.
