Nano/Micro Surface Texturing and Enhancing of Photovoltaic Cells Efficiency by Using UV Femtosecond Laser Pulses

Abstract

A fast laser texturing technique has been utilized to produce micro/nano surface textures in Silicon by means of UV femtosecond laser. We have prepared good absorber surface for photovoltaic cells. The textured Silicon surface absorbs the incident light greater than the non-textured surface. The results show a photovoltaic current increase about 21.3% in toe dimension laser textured area.
