我们证明了通过在活性层和上电极之间插入C60夹层来增强聚合物：PCBM共混物光伏电池的器件性能。通过旋涂聚合物{（聚（2-甲氧基-5-（2′-乙基-己氧基）-1，4-亚苯基亚乙烯基）（MEH-PPV）或（聚（3-己基噻吩）（P3 HT）和富勒烯衍生物[5，6]-苯基-C61-丁酸甲酯（PCBM））}制备活性层，然后沉积C60夹层和LiF/Al电极。与没有C60层的电池相比，具有C60夹层的两种聚合物电池显示出功率转换效率的显著增加。
We demonstrate the enhancement of the device performance in polymer:PCBM blend photovoltaic cells by insertion of C60 interlayer between the active layer and the upper electrode. The active layer was fabricated by spin coating of a polymer {(poly(2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene)(MEH-PPV) or (poly(3-hexylthiopene)(P3HT) and fullerene derivative [5,6]-phenyl-C61-butyric acid methyl ester(PCBM)}, then the C60 interlayer and LiF/Al electrode were deposited. The both polymer cells with C60 interlayer showed significant increase in the power conversion efficiency compared to cells without the C60 layer.
