Basically, a solar cell is a P-N junction that absorbs light, releases electrons and holes, creating a voltage in the cell, which is then applied to a load [3]. The DC current is converted into 240-volt AC current using an inverter for different applications. 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.
