摘　　要：钙钛矿太阳能电池(perovskite solar cells,PVSCs)因长期稳定性差和制造成本高难以实现工业化生产。其制备中最常用的空穴传输材料(hole-transporting materials,HTMs)为2,2′,7,7′-四[N,N-二(4-甲氧基苯基)氨基]-9,9′-螺二芴,需一定量吸湿添加剂以实现高效的空穴提取,导致对水敏感的钙钛矿层受到破坏。无掺杂HTMs避免了吸湿添加剂的使用,且成本低、合成步骤简单。综述了应用于n-i-p型PVSCs的YT5、M7-TFSI、P3HT、PBDB-Cz等高效率无掺杂有机小分子以及聚合物HTMs,提出了理想HTMs在器件性能、分子结构、合成条件、经济成本等方面的设计原则,并展望了无掺杂HTMs在PVSCs商业化过程中的应用前景。Perovskite solar cells(PVSCs)face challenges in industrial production due to their low long-term stability and high manufacturing costs.The most commonly used hole-transporting materials(HTMs)for PVSCs are 2,2′,7,7′-tetrakis[N,N-di(4-methoxylphenyl)amino]-9,9′-spirbiuorene,which require necessary hydrophilic additives to achieve efficient hole extraction but lead to the damage of the water-sensitive perovskite layer.The employment of dopant-free HTMs can not only avoid the use of hydrophilic additives but also offer advantages in terms of cost and synthesis simplicity.This review introduces highly efficient dopant-free organic small molecules and polymer HTMs,such as YT5,M7-TFSI,P3HT,PBDB-Cz,among others,used in n-i-p type PVSCs.It outlines the design principles for ideal HTMs regarding device performance,molecular structure,synthesis conditions,and economic cost,and provides an outlook on the potential for commercial application of dopant-free HTMs in PVSCs.
