制备了共轭聚合物聚[2-甲氧基-5-（3′，7 ′-二甲基辛氧基）-1，4-亚苯基亚乙烯基]（MDMO-PPV）和聚（3-己基噻吩）（P3 HT）与C60纳米晶须（C60 NWs）的复合膜。共轭MDMO-PPV聚合物的光致发光在复合膜中被有效地猝灭，表明共轭聚合物与C60纳米线之间存在较强的相互作用。使用C60 NW（共轭聚合物）复合膜制造光伏器件，导致具有短长度薄C60 NW的P3 HT的功率转换效率为约0.01%，这高于先前报道的厚C60纳米棒的功率转换效率。本研究为新型光伏器件中C60纳米线的类型选择和合适的聚合物提供了新的指导。
Composite films of conjugated polymers, such as poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) and poly(3-hexylthiophene) (P3HT), with C60 nanowhiskers (C60NWs) were prepared. The photoluminescence originating from the conjugated MDMO-PPV polymers was effectively quenched in the composite film, indicating a strong interaction between the conjugated polymer and C60NWs. The photovoltaic devices were fabricated using C60NW (conjugated polymer) composite films, resulting in a power conversion efficiency of ~0.01% for P3HT with short length thin C60NWs, which is higher than that previously reported for thick C60 nanorods. The present study gives new guidance on the selection of the type of C60NWs and the appropriate polymer for new photovoltaic devices.
