A semitransparent flexible metal halide perovskite (MHP) solar cells were demonstrated by reproducible dry stamping transfer of a poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid) (PEDOT:PSS, PH1000) transparent flexible top electrode onto poly(ethylene terephthalate) (PET)/indium tin oxide (ITO)/PEDOT:PSS (AI4083)/MHP/[6,6]-phenyl-C-butyric acid methyl ester (PCBM). The reproducible transfer of the PEDOT:PSS top electrode was enabled by the modification of PEDOT:PSS with poly(ethylene imine) (PEI)/2-methoxyethanol (2-MEA) solution. In addition, the PEI/2-MEA modification to PEDOT:PSS resulted in improved conductivity and reduced work function of the top electrode. Therefore, we could fabricate highly efficient flexible semitransparent MHP solar cells with >13% (active area = 1 cm) power conversion efficiency.
通过将聚（3,4 - 乙撑二氧噻吩）：聚（苯乙烯磺酸）（PEDOT:PSS，PH1000）透明柔性顶电极可重复地干压转移到聚对苯二甲酸乙二酯（PET）/氧化铟锡（ITO）/PEDOT:PSS（AI4083）/金属卤化物钙钛矿（MHP）/[6,6]-苯基-C-丁酸甲酯（PCBM）上，展示了一种半透明柔性金属卤化物钙钛矿（MHP）太阳能电池。通过用聚乙烯亚胺（PEI）/2-甲氧基乙醇（2-MEA）溶液对PEDOT:PSS进行改性，实现了PEDOT:PSS顶电极的可重复转移。此外，对PEDOT:PSS进行的PEI/2-MEA改性提高了顶电极的导电性并降低了其功函数。因此，我们能够制造出功率转换效率大于13%（有源面积 = 1平方厘米）的高效柔性半透明MHP太阳能电池。
