Abstract：We compare the electrical, optical, and surface properties of the PEDOT:PSS/Cu nanowires (Cu NWs)/PEDOT: PSS (PCP) multilayer for organic solar cells. It is demonstrated that the electrical and optical properties of the PEDOT could be improved by the insertion of a Cu NW layer due to its very low resistivity and surface morphology. The organic bulk heterojunction solar cell fabricated on the multilayer exhibits a higher power conversion efficiency than devices based on the PEDOT:PSS or PEDOT:PSS/Cu NWs layer. Moreover, the PCP multilayer can improve cell-performances such as a fill factor and the internal resistance in the device due to horizontally well-aligned Cu NWs. The results suggest that the PCP multilayer is a promising low-cost and low-temperature processing buffer layer candidate for low-cost organic photovoltaics.
