Broadband light absorption enhancement in solar cells using plasmonic nanoparticles and novel physical effects has attracted a great deal of attention in recent years. The incorporation of metallic nanoparticles in organic solar cells has been conducted for improving photovoltaic performances. However, the plasmonic related scattering and local field enhancement effect are hard to cover the whole wavelength range of active polymer response spectrum by only using single-component metal nanoparticles. Here, we report a facile method to fabricate polymer solar cells incorporated by Au, Ag nanoparticles and Ag-Au bimetallic nanoparticles. The strategy employing binary metal nanoparticles into will provide improvement in optical properties and performance of polymer solar cells. |
