Solar cells are primarily made of silicon and do not contain any corrosive materials or moving parts. Silicon makes up 27.7% of the Earth’s crust and is the second most abundant element after oxygen. The silicon wafers’ surfaces are infused with minute amounts of impurities primarily Boron or Phosphorous in order to promote the production of electricity. Other materials used in solar panels are – Outer surface: Glass. Electrical Contacts: palladium, silver, nickel, or copper. Panel Frame: Aluminium.

Photovoltaic energy is produced when sunlight is converted into energy with the use of solar cells or semiconductors. 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. The term “photovoltaic” has two parts: photo, a Greek word meaning light, and voltaic, a reference to electrical energy innovator Alessandro Volta.
