摘要: 利用溶剂热法可控制备了具有不同质量比的还原氧化石墨烯/CuInS2 量子点(rGO/CuInS2-QDs) 杂化材 料。将rGO/CuInS2-QDs 杂化材料与聚(2-甲氧基-5-(2- 乙基己氧基)-1, 4-苯撑乙烯基) (MEH-PPV) 共混作为光活 性层, 制备了石墨烯基杂化聚合物太阳能电池, 研究了rGO/CuInS2-QDs 杂化受体材料中rGO 与CuInS2-QDs 的 质量比(x) 以及聚合物给体材料MEH-PPV 与rGO/CuInS2-QDs 杂化受体材料的质量比(w) 对器件性能的影响。 结果表明, 光活性层复合膜中rGO/CuInS2 (x = 0:25) 杂化受体材料含量由10% (w = 9) 增加到17% (w = 5) 时, 器 件的电子收集效率(c) 由0.61 提高到0.78, 使得器件的光电转换效率得到提高。

Abstract: Reduced graphene oxide-CuInS2 quantum dots (rGO/CuInS2-QDs) hybrids with different weight ratios of rGO and CuInS2-QDs are controllably synthesized by solvothermal method. Then graphene based hybrid polymer solar cells are fabricated by blending the rGO/CuInS2-QDs hybrid with poly(2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylene vinylene) (MEH-PPV) as photoactive layer, and the effects of the weight ratio (x) of rGO to CuInS2-QDs in rGO/CuInS2-QDs hybrid acceptor material and the weight ratio (w) of MEH-PPV donor material to rGO/CuInS2-QDs hybrid acceptor material in photoactive blend on device performance are studied. The results show that when the content of rGO/CuInS2 (x = 0:25) hybrid acceptor material increases from 10% (w = 9) to 17% (w = 5), the electron collection efficiency (c) of the device increases from 0.61 to 0.78, which improves the photoelectric conversion efficiency of the device.
