The biggest disadvantage of solar cells is that it has low solar power conversion efficiency typically 14%. So as to improve the power conversion performance, several attempts was made by researchers and once such technique is to reduce the reflection by providing textures on the solar cells. This texture will reduce the reflectance and thereby increase the solar power conversion efficiency. In this work, an investigational study was conducted to improve an energy efficiency of solar PV cells. Here Cu, Ag, Al was deposited for metallization purpose at specific places by using RF and DC magnetron sputtering process. The input parameters such as power, deposition time and substratum temperature were optimized during the sputtering process and the corresponding coating thickness, optical properties and surface topography were investigated. The coating thickness and surface roughness were increased as power increased from 15W to 45W. Average surface roughness (Ra) of 6nm and was obtained at the optimum power of 45W and deposition rate of 5-7 mins. The surface morphology and topography was characterized by using SEM and AFM which shows uniform coating with spherical shaped with densely packed nanostructures with increase in grain size were observed and elemental composition were confirmed by using EDAX. The absorption and reflection were investigated by using UV-VIS-NIR spectrometer indicates that the optical absorption increased from 1.2% to 1.68% at the wavelength range from 250 to 314nm. The reflection was reduced from 13.4% to 3.67% and the conversion efficiency was increased from 14.22% to 16.63%. This paper reports the complete experimental details, results and analysis.
