CONSTRUCTION OF SOLAR CELL

Abstract: A solar cell or photovoltaic is a device  which directly converts photon or solar light or sunlight into electricity. Radiation (Light shining) on the solar cell produces both a current and a voltage which create  electric power in most solar panel. This process requires a Material Medium in which the absorption of photon raises an electron to a higher energy state, and the motion of this excited energy electron from the solar cell into an external circuit. The electron then dissipates its energy in the external circuit and returns to the solar cell. A various materials are required for photovoltaic energy conversion, but in practice nearly all photovoltaic energy conversion uses semiconductor materials(C,Si,Ge,Sn) in the form of a p-n junction. With regard to the development of  solar energy, in this paper we will design and construct solar cells that can power appliances.                 1
