How does a photovoltaic cell work?

A photovoltaic cell is an essential component in capturing solar energy. It consists of semiconductor material, typically silicon, that absorbs sunlight. When the sun's rays hit the cell, they knock electrons loose, creating an electric current. This process allows the cell to generate power, transforming sunlight into usable electricity.

What is the working principle of a photovoltaic cell?

Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
