Characteristics of plasmonic solar cells are studied. In particular, amorphous silicon thin films dispersed with Ag nanoparticles are studied theoretically using effective medium theory. The dependence of electron generation rate and the current density on the thickness of the film is investigated. The effect of dispersion of Ag nanoparticles on the absorption coefficient of nanocomposite is also investigated. The dependence of external quantum efficiency (EQE) on wavelength is estimated. There is almost no change in the open circuit voltage of the film with the introduction of Ag nanoparticles but there is an appreciable enhancement of closed circuit current density with Ag nanoparticles dispersed.
Keywords: Plasmonic solar cells, nanoparticles, effective-medium theory, external quantum efficiency.
