A new donor-acceptor polymer based on 9,9-dioctylfluorene is synthesized and tested in organic photovoltaic devices. Results show that the polymer exhibits good solubility in a range of organic solvents and has a high hole mobility. When blended with a PC70 BM acceptor and fabricated into a bulk heterojunction, photovoltaic devices having a maximum power conversion efficiency (PCE) of 6.2% and a peak external quantum efficiency of 74% are created. Such efficiencies are realized without any necessity for solvent additives or thermal annealing protocols.
一种基于 9,9-二辛基芴的新型给体-受体聚合物被合成并在有机光伏器件中进行了测试。结果表明，该聚合物在一系列有机溶剂中具有良好的溶解性和较高的空穴迁移率。当与 PC70BM 受体共混并制成体异质结时，制备的光伏器件的最大能量转换效率（PCE）为 6.2%，峰值外量子效率为 74%。这些效率的实现并不需要任何溶剂添加剂或热退火协议。
