A solar cell is an electronic device which directly converts sunlight into electricity. Fig. A solar cellis also known as photovoltaic cell which produces electric current when the surface is exposed to sunlight. The process of conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. 7.
