Effect of nanoparticle size to improvement in absorption in Plasmonic solar cell

In last decades, plasmonics gives very high attention and closely involves in the main domains of nanophotonics which can control of optical fields at the nanodimension level. Its most striking property is to concentrate and enhance the electromagnetic field on the nanometer 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 most part of total loss in solar cell. In this paper, we investigate the effect of nanoparticle dimension for enhancement of extinction in terms of absorption and scattering by means of surface plasmon and also studied finite-difference time domain based proposed model which shows improvement in various simulated surface plasmonic fields components.
