ANALYSIS OF SOLAR CELL WITH MgO-ZnO ANTI-REFLECTIVE COATING

In general solar PV panels are used without any anti-reflective coating. Its efficiency is only about 6-7%. Surface passivation plays a significant role in upgrading solar cell performance. When the anti reflection coating is used on solar cell, the efficiency gets increased for a specified thickness of coating. In this study the combination of MgO-ZnO material is used as an anti- reflective coating on silicon solar cell. The thickness of the coating is optimized 86nm and 75nm for p-type single crystalline silicon solar PV cell, considering the optical response in the 400nm to 800nm wavelength range. Theoretical model has been developed to determine the refractive index and other related optical properties such as transmissivity, reflectivity for the solar PV panel without the anti-reflective Coating. The combination of MgO-ZnO material showed higher refractive index value. This is investigated theoretically and compare the optical properties of solar cell with coating and without coating.
