Enhancement of light absorption of solar cells using nanoscale structures and novel physical effects has attracted a great deal of attention in recent years. Especially, utilizing plasmonic nanoparticles (NPs) such as Au and Ag NPs is considered as one of the promising methods for significant enhancement of local electromagnetic fields and thus improves the optical properties of the nanostructure devices. In addition, the incident photons can be scattered over a longer propagation path in the active layer by metallic nanostructures. These features can potentially benefit the light absorption and photocurrent generation of polymer solar cells. Thus, the incorporation of metallic NPs in organic solar cells has been conducted for improving photovoltaic performances. Especially, recent studies has been devoted to adding plasmonic nanoparticles into bulk heterojunction (BHJ) polymer because the method enhances the overall performance of the cell; reduction of the device resistance and efficient increase in the optical path length in the polymer. However, most metal nanoparticles utilized were prepared in aqueous media, which means the nanoparticles have incompatible surface to organic solvent containing BHJ polymer. Here, we examined the effects of various organic based ligands on dispersion of plasmonic metal nanoparticles in P3HT/PCBM layer and the performance of organic solar cells. The strategy employing optimum ligands to disperse metal nanoparticles in BHJ layer would provide improvement in optical properties and performance of polymer solar cells.
