Abstract: Recently, plasmonics offers very high attention and greatly deals with various field includes the nanophotonics domain. In the plasmonic field, when the nanoparticle is much smaller than the wave length of light, coherent oscillation of the conduction band electrons induced by interaction with an electromagnetic field and conjointly improves absorption through scattering. In this paper, we studied the effectiveness of nanoparticle dimension to enhance extinction in terms of absorption and scattering for silver, gold, copper and aluminium nanoparticles. We also studied finite difference time domain-based solar cell model that improves various simulated plasmonic field components and observed that the high sensitivity of the surface plasmon resonance spectrum of noble metal nanoparticles to adsorbate induced changes in dimension and dielectric constant of the surrounding nanoenvironment. We also observed that noble metal specifically silver and gold nanoparticles significantly improve optical absorption than copper and aluminium nanoparticles.

Keywords: plasmon; absorption; extinction; scattering; surface plasmon polariton; finite difference time domain.
