Enhancement of optical absorption in Plasmonic thin film solar cell

Abstract

Recently, plasmonics gives very much interest and closely involves in the main domains of nanophotonics that can control of optical fields at the nanoscale level. Its remarkable property is to concentrate and enhance the electromagnetic field on the nanometres scale especially in solar cell. In plasmonic field, Nobel metals used as nanoparticle where density of electron gas which oscillates at surface Plasmon frequency at the same time also improves absorption by scattering. So the use of plasmonic in solar cell gives better opportunity to enhance efficiency by absorption as the optical spectrum loss are main part of total loss in solar cell. So we investigate the induction of surface Plasmon theory for enhancement of extinction in terms of absorption and scattering. In this paper, we also studied finite-difference time domain based proposed model and find various plasmonic field component of Eigen value and characterized optical improvement in plasmonic thin film solar cell.
