摘要： Polymer solar cells based on poly (2-methoxy-5-(2'-ethyl-hexyloxy)-1, 4-phenylene vinylene) (MEH-PPV):1-(3-methoxycarbonyl)-propyl-1-1-phenyl-(6,6)C61(PCBM):3, 10-di(trifluoromethane) triphenodioxazine (TFTD) was fabricated using spin coating technology. The absorption spectra of MEH-PPV: PCBM: TFTD film coated from chlorobenzene solution was broadened and showed higher intensity compared with that of the pure MEH-PPV. The TFTD acting as electron acceptors in combination with PCBM induced the photoluminescence (PL) quenching of MEH-PPV, which were associated with the photoinduced charge transfer characteristics of composite film. Further, a photovoltaic conversion efficiency up to 1.03% under 16.7 mW/cm(2) white light illumination was achieved in the MEH-PPV: PCBM: TFTD system. (c) 2008 Elsevier Ltd. All rights reserved.
