Abstract

Organic semiconductors play a crucial role in the architecture of thin-film electronic devices, particularly as hole transport layers in solar cells. These materials are essential for overcoming significant barriers to improving device lifetime and performance. Among these materials, the small molecule 2,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene, known as spiro-OMeTAD, has been instrumental in the development of high-efficiency perovskite solar cells (PSCs) for over a decade. During this time, the additives used to tune the properties of spiro-OMeTAD have undergone significant evolution. Based on current literature, this review examines how interactions in the doping of spiro-OMeTAD have influenced the performance of PSCs, discusses alternatives for future development by highlighting their advantages and limitations, and provides insights into whether spiro-OMeTAD remains the best hole transport material for n-i-p structured PSCs.

螺-OMeTAD 中多潘诱导的相互作用：推进过氧化物太阳能电池的空穴传输

有机半导体在薄膜电子设备的结构中发挥着至关重要的作用，尤其是作为太阳能电池的空穴传输层。这些材料对于克服提高设备寿命和性能的重大障碍至关重要。在这些材料中，小分子 2,2′,7,7′-四[N,N-二(4-甲氧基苯基)氨基]-9,9′-螺二芴（又称螺-OMeTAD）十多年来在开发高效率的过氧化物太阳能电池（PSCs）中发挥了重要作用。在此期间，用于调整螺-OMeTAD 性能的添加剂经历了重大演变。本综述以现有文献为基础，探讨了螺-OMeTAD 掺杂过程中的相互作用如何影响了 PSC 的性能，通过强调其优势和局限性讨论了未来发展的替代方案，并深入分析了螺-OMeTAD 是否仍然是 ni-p 结构 PSC 的最佳空穴传输材料。
