　　Significant improvement in the power conversion efficiency(PCE)of polymer solar cells(PSCs)has been observed when the active layer was treated with a mixture of methanol and water(M ∶ W).For the PSCs based on ITO/PEDOT:PSS/PCDTBT:PC71BM/Al,the PCE was 6.58%when the surface of the PCDTBT:PC71BM film was treated with pure methanol.However M ∶ W(6 ∶ 1)treatment on the PCDTBT:PC71BM film could further improve the PCE to 7.44%which is even higher than the PCE values of the PSCs with LiF(6.00%)or PFN(6.88%)as a cathode interlayer.

溶液法处理对活性层形貌影响的研究

：添加剂DIO 已被认为是一种有效可靠且适用面较为广泛的活性层形貌优化手段，在公开发表的很多工作中都采用了这一工艺手段。最近，研究发现添加剂DIO 对活性层形貌相分离和垂直方向上的分布的作用是相悖的，即DIO 掺杂有利于形成较小尺寸的相分离，促进激子解离，同时却会使得给体材料向低功函数的阴极扩散，损害电荷传输。针对上述问题，我们提出了溶液法处理含有DIO 添加剂的活性层表面的方法来改善这种DIO
