Improving the Efficiency of Thin Film Amorphous Silicon Solar Cell by Changing the Location and Material of Plasmonic Metallic Nanostructures

Abstract

In this work we present a 3D-finite difference time domain (FDTD) simulation of ultra thin amorphous silicon solar cell. The optical generation rate and plasmonic resonance enhance absorption in thin film cell in which silver nanoparticles are imbedded inside the depletion region of p-n junction. Here, the operation of thin film solar cell has been analyzed. Here, by inserting the metal nanoparticles within the active layer in the depletion region of the p-n junction, a new structure has been introduced. We have utilized three different materials, gold, silver and aluminium and the efficiencies of 5.27%, 5.3% and 3.74% have been obtained respectively. The results indicate a significant increase in the efficiency of proposed solar cell with silver nanoparticles.
