摘　　要：采用Suzuki偶合反应制备了不同9,9-二(丙酸二甲氨基乙酯)芴(FDMAEA)结构单元含量的9,9-二(丙酸二甲氨基乙酯)芴-9,9-二辛基芴共聚物(PF8FDMAEA)。采用溶剂热法制备了TiO2纳米醇分散液,将其与PF8FDMAEA进行复合,得到PF8FDMAEA/TiO2杂化物,并用于聚合物太阳能电池电子传输层。通过紫外光谱、荧光光谱和原子力显微镜等对PF8FDMAEA/TiO2杂化物进行了表征,并研究了PF8FDMAEA/TiO2杂化物作为电子传输层的聚合物太阳能电池性能。结果表明,PF8FDMAEA/TiO2杂化物能够有效地提高聚合物太阳能电池的性能。以PF8FDMAEA/TiO2杂化物为电子传输层,结构为ITO/PEDOT∶PSS/P3HT-PC61BM/(P1/20%TiO2)/Ag的聚合物太阳能电池的光电转换效率可达2.43%,比相应的无电子传输层的聚合物太阳能电池提升了111%。Poly[(9,9-bis(dimethylaminoethylpropanoate)-2,7-fluorene)-co-2,7-(9,9-dioctylfluorene)]copolymers with different contents of 9,9-bis(dimethylaminoethylpropanoate)fluorene structural unit were synthesized by Suzuki coupling reaction.The nano TiO2 alcohol dispersion was prepared by solvothermal method.The PF8FDMAEA/TiO2 hybrids for electron transport layer of polymer solar cell were obtained by blending PF8FDMAEA and TiO2 alcohol dispersion.The PF8FDMAEA/TiO2 hybrid were characterized by UV-Vis absorption spectra,fluorescence emission spectra and atomic force microscopy.The performance of polymer solar cells with PF8FDMAEA/TiO2 hybrids as electron transport layers was investigated.It was found that the performance of polymer solar cells can be effectively improved by the PF8FDMAEA/TiO2 hybrids electron transporting layer.The power conversion efficiency of the polymer solar cell with PF8FDMAEA/TiO2 hybrid as the electron transport layer and structure of ITO/PEDOT∶PSS/P3HT-PC61BM/(P1/20%TiO2)/Ag was 2.43%,which was 111%higher than that of polymer solar cells without the corresponding electron transporting layer.
