Localized surface plasmon mediated polymer solar cells (PSCs) were fabricated using the Ag/SiO2 nanoparticles (NPs). The inverted PSC structure without poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) was prepared due to the efficient insertion of Ag/SiO2 NPs in the vicinity of active layer, which led to an enhancement in photoconversion efficiency (PCE). This enhancement mainly comes from the light scattering by the SiO2 shell and the localized surface plasmon effect by the Ag core, but we also considered the structural issues such as the NP distribution, the swelling of the active layer and of the metal electrode.
