Perovskite solar cells (PSCs) have been attracting considerable attention because of their low fabrication cost and impressive energy conversion efficiency. Most PSCs are built on transparent conductive oxides (TCOs) such as fluorine-doped tin oxide (FTO) or indium tin oxide (ITO), which are costly and rigid. Therefore, it is significant to explore alternative materials as the transparent electrode of PSCs. In this study, highly conductive and highly transparent poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (
PEDOT
PSS) films were investigated as the transparent electrode of both rigid and flexible PSCs. The conductivity of
PEDOT
PSS films on rigid glass or flexible poly(ethylene terephthalate) (PET) substrate is significantly enhanced through a treatment with methanesulfonic acid (MSA). The optimal power conversion efficiency (PCE) is close to 11% for the rigid PSCs with an MSA-treated
PEDOT
PSS film as the transparent electrode on glass, and it is more than 8% for the flexible PSCs with a MSA-treated
PEDOT
PSS film as the transparent electrode on PET. The flexible PSCs exhibit excellent mechanical flexibility in the bending test.

钙钛矿太阳能电池（PSC）因其制备成本低和令人印象深刻的能量转换效率而备受关注。大多数PSC基于透明导电氧化物（TCO）构建，如氟掺杂氧化锡（FTO）或氧化铟锡（ITO），这些材料成本高且质地坚硬。因此，探索替代材料作为PSC的透明电极具有重要意义。在本研究中，研究了高导电性和高透明度的聚（3,4 - 乙撑二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）薄膜作为刚性和柔性PSC的透明电极。通过用甲磺酸（MSA）处理，刚性玻璃或柔性聚对苯二甲酸乙二酯（PET）基板上的PEDOT：PSS薄膜的导电性显著提高。对于以经MSA处理的PEDOT：PSS薄膜作为玻璃上透明电极的刚性PSC，最佳功率转换效率（PCE）接近11%，对于以经MSA处理的PEDOT：PSS薄膜作为PET上透明电极的柔性PSC，该效率超过8%。柔性PSC在弯曲测试中表现出优异的机械柔韧性。
