| Abstract: | For small metal nanoparticles in the quasistatic limit, the scattering and absorption cross sections are derived. The scattering efficiency is also deduced under Durde model with- in the scope of visible and infrared light. Based on the scattering features of the metal nanop- articles, The light absorbing efficiency of the thin-film photovoltaic cell may be enhanced. The basic principle of enhancing the photovoltaic cell efficiency is presented briefly in this pa- per. |
