摘要: Abstract The paper reports novel ternary MEH-PPV-CuInS2/ZnO solar cells fabricated by incorporating CuInS2 quantum dots (QDs) into pristine MEH-PPV as light-harvester and vertically aligned ZnO nanorod array electron acceptor. Results show that, exhibit increased photovoltaic performance compared to MEH-PPV/ZnO devices the dependent on weight ratio (R) between MEH-PPV, resulting in a peak power conversion efficiency of 2.48% for R = 0.6 at 15.85 mW/cm2 monochromatic illumination. It is revealed that Jsc due improved light-harvesting, additional MEH-PPV/CuInS2 interfaces exciton dissociation, formation channels effective charge transport, while Voc decreased recombination are attributed modification surface QDs which reduces defect concentration ZnO. However, Jsc, too high R value serious aggregations inorganic nanocrystals not well dispersed organic matrix.
