title = "Improving efficiency of organic photovoltaic cells with pentacene-doped CuPc layer",
abstract = "We have fabricated efficient heterojunction organic photovoltaic (OPV) cells based on pentacene-doped copper(II) phthalocyanine (CuPc) layer as donor and fullerene (C60) layer as acceptor. The power conversion efficiency of 4\% pentacene-doped CuPcC60 OPV cell (3.06\%) is increased by 77\% compared with that of the standard CuPcC60 OPV cell (1.73\%). The efficiency improvement can be attributed to the higher carrier mobility instead of the stronger photon absorption of the pentacene-doped CuPc layer.",
