We fabricate efficient bulk heterojunction organic photovoltaic (OPV) device based on poly(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene) (MEH-PPV), with copper(Ⅱ) phthalocyanine (CuPc) used as a donor and -phenyl C61-butyric acid methyl ester (PCBM) serving as an acceptor. The power conversion efficiency of the MEH-PPV/PCBM OPV device with 15% CuPc (1.41%) increases by 12% compared with that of the standard MEH-PPV/PCBM device (1.26%). The efficiency improvement can be attributed to the CuPc supplemental absorption and higher mobility than MEH-PPV, leading to increased short-circuit current density.
