【Abstract】 The up-to-date progresses of application of surface plasmons of metallic nanostructures for enhancing organic solar cells performance is presented.The surface plasmons excitation in nanostructures depends on the properties of material,size,shape,density,and surrounding dielectric environment,which can be adjusted to enhance light absorption of the active layer.Furthermore,efficiency of excitions into charge carriers in organic solar cell materials can be improved by strong electric field near surface of metal nanostructures dissociation.Therefore,applying metallic nanostructures in organic solar cell is deemed a promising way to enhance the photoelectric conversion efficiency further.更多还原
