Paper Abstract
Recent scientific publications have highlighted the possibility of enhancing solar conversion efficiency in thin
film solar cells using surface plasmon (SP) waves and resonances. One main strategy is to deposit layers of
metal nanoparticles on the top of a thin film silicon solar cell which can increase light absorption and
consequently the energy conversion in the frequency range where the silicon intrinsic absorptance is low. In
this paper, we investigate the effects produced on the light absorption and scattering by silver nanoparticles,
arranged in a periodic pattern, placed on the top of amorphous silicon (α-Si) thin layer. We propose different
geometry of metal objects, quantifying the scattering (back and forward) determined by the nanoparticles in
dependence of their shapes and Si thickness. The analysis reveals that the thickness of the substrate has huge
influence on the scattering, in particular on the back one, when the nanoparticles have corners, whereas it
seems less dramatic when rounded profiles are considered (nanospheres).
