In the recent year, plasmonic effect in thin films by using metal nanoparticles, for enhancement of light trapping is considerably important among the researchers. Light trapping enhancement is a huge challenge in the thin film solar cell because of its limited thickness. Effective Light trapping can enhance the conversion efficiency up to 2-3% of the solar cell . Surface plasmon resonance (SPR) is used for enhancement of light trapping in solar cell by interacting conduction electrons of metal nanoparticles to the incident photons .
