Plasmonic Effect Due to Silver Nanoparticles on Silicon Solar Cell

Plasmonic effects in thin film silicon solar cell are an emerging technology and area of rigorous research for the researchers from past couple of years. It has promising application in solar cells fabrication industries where it used nonoscale properties of silver or gold nanoparticles that incorporated in interface between the metal and dielectric contacts that enhance the light trapping properties of thin film silicon solar cells by increase absortence capacity and generation of hot-electrons that enhance the photo currents in the solar cell. In this paper, we had taken two different thickness of silver thin film (AgNPs) of 5.9 nm and 7.8 nm in 2 X 10-4(Torr) and 2.5 X 10-4(Torr) pressure environment for investigation purpose. Samples were annealed at different temperature ranges for definite time period under vacuum condition of 4.5 X 10-6 Torr. From this experimental study reflectance reduces 13% to 11% due to plasmonic effect and enhancement in the conversion efficiency of the solar cell.
