what is photovoltaic energy?

The term "photovoltaic" has two parts: photo, a Greek word meaning light, and voltaic, a reference to electrical enegry innovator Alessandro Volta. In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect, the production of a volt by use of a semiconductor. This discovery prompted further experimentation with light sources and semiconductors, which led to the invention of solar cells that produce photovoltaic energy.

 The energy obtained from sun as soler energy is directly transformed into electrical energy by some soler cells made up of silicon or germanium. this technology is called photovolatic technology. And energy formed is called photovolatic energy.

 Photovoltaic energy is produced when sunlight is converted into energy with the use of solar cells or semiconductors. These semiconducting cells are usually made of silicon and do not contain any corrosive materials or moving parts. As long as the solar cells are exposed to light, they will produce photovoltaic energy with a minimum of maintenance. This energy is also environmentally clean, quiet, and safe.
