2,2',7,7'-Tetrakis(N,N-di--methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD), as an organic small molecule material, is the most commonly employed hole transport material (HTM) in perovskite solar cells (PSCs) because of its excellent properties that result in high photovoltaic performances. However, the material still suffers from low conductivity, leading to the necessary use of dopants and oxidative processes to overcome this issue. The spiro-OMeTAD oxidation process is highlighted in this review, and the main parameters involved in the process have been studied. Furthermore, the best alternatives aiming to improve the spiro-OMeTAD electrical properties have been discussed. Lastly, this review concludes with suggestions and outlooks for further research directions.
2,2',7,7'-四（N,N-二甲氧基苯胺）-9,9'-螺二芴（spiro-OMeTAD）作为一种有机小分子材料，因其优异的性能而成为钙钛矿太阳能电池（PSC）中最常用的空穴传输材料（HTM），这些性能可带来高光伏性能。然而，该材料仍存在导电性低的问题，这导致需要使用掺杂剂和氧化工艺来克服这一问题。本文综述重点介绍了spiro-OMeTAD氧化过程，并研究了该过程中涉及的主要参数。此外，还讨论了旨在改善spiro-OMeTAD电学性能的最佳替代方案。最后，本综述给出了进一步研究方向的建议和展望。
