Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has high optical transparency in the visible light range and low-temperature processing condition, making it one of the most widely used polymer hole transport materials inverted perovskite solar cells (PSCs), because of its high optical transparency in the visible light range and low-temperature processing condition. However, the stability of PSCs based on pristine PEDOT:PSS is far from satisfactory, which is ascribed to the acidic and hygroscopic nature of PEDOT:PSS, and property differences between PEDOT:PSS and perovskite materials, such as conductivity, work function and surface morphology. This review summaries recent efficient strategies to improve the stability of PEDOT:PSS in PSCs and discusses the underlying mechanisms. This review is expected to provide helpful insights for further increasing the stability of PSCs based on commercial PEDOT:PSS.

聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS）在可见光范围内具有高光学透明度且具备低温加工条件，这使其成为倒置钙钛矿太阳能电池（PSC）中使用最广泛的聚合物空穴传输材料之一，原因在于其在可见光范围内的高光学透明度和低温加工条件。然而，基于原始PEDOT:PSS的PSC的稳定性远不能令人满意，这归因于PEDOT:PSS的酸性和吸湿性，以及PEDOT:PSS与钙钛矿材料之间的性能差异，如导电性、功函数和表面形态。本文综述总结了近期提高PEDOT:PSS在PSC中稳定性的有效策略，并讨论了其潜在机制。预计本文综述将为进一步提高基于商用PEDOT:PSS的PSC的稳定性提供有益的见解。
