A High Efficiency Solar Cell and System

Abstract

Solar cells have been a cost-effective technology of producing a sustainable electricity using renewable sun energy. In this paper we have focused our research on an innovative yet simple approach including concentrated PV (Photovoltaic) cells using Fresnel lens. In our findings we tried to expound the refracting properties of the Fresnel lens to concentrate the solar spectrum on to a photovoltaic cell. MATLAB Simulink simulation was used to demonstrate that the intensity of the incident light (photons energy) prominently influences the output power and hence efficiency of a given PV cell. The final conclusion of the paper was helpful in achieving the overall increase in efficiency of a PV cell.
