摘要： 研究了刮涂制备P3HT∶PCBM(P3HT：聚3-己基噻吩，PCBM：[6,6]-苯基-C61-丁酸甲酯)活性层的过程中，基底温度对P3HT∶PCBM活性层薄膜性质和电池性能的影响。 结果表明，提高基底温度在缩短薄膜干燥时间的同时，抑制了PCBM相的大尺度聚集，并改善了P3HT∶PCBM薄膜中P3HT在（100）方向上的结晶程度，但降低了π-π共轭方向上的有序度。 制备的光伏电池经过进一步退火处理后可形成良好的互穿网络结构，能量转换效率可达3.93%。

Abstract: The effects of the substrate temperature on the performance of active layers and characteristics of the polymer solar cells fabricated with doctor-blading were studied. As the substrate temperature increases, the drying time of wet film could be shortened while the large scale aggregation of [6,6]-phenyl C61-butyric acid methyl ester(PCBM) phase could be restrained. Along with the increase of substrate temperature, both the crystallinity of poly(3-hexylthiophene)(P3HT) at the(100) direction and the producing efficiency of the film were increased while the ordering of the π-π stacking was lowered. After annealing, an interpenetrate network was formed in the active layer of the polymer photovoltaic cell and the power conversion efficiency could reach up to 3.93%.

Key words: doctor-blade coating, polymer photovoltaic cells, substrate temperature
