摘　　要：基于传统空穴传输材料(HTM)的钙钛矿太阳能电池(PSC)已经实现了超过25%的能量转换效率,然而这些HTM通常需要添加吸湿性掺杂剂来实现高迁移率和可加工性,从而降低了器件稳定性。为解决该问题,无掺杂HTM受到广泛关注。总结了近年来用于高效PSC的无掺杂聚合物HTM的结构和性能,并分析了其中的构效关系,提出了高效无掺杂聚合物HTM的结构设计原理,并展望了未来的发展趋势。Perovskite solar cells(PSC)based on conventional hole-transporting materials(HTM)have achieved power conversion efficiency of over 25%.However,the dopants with hygroscopic nature are commonly used to increase the hole mobility or thefilm-forming ability of the HTM,which reduces the stability of devices.To solve this problem,dopant-free polymeric HTM is concerned widely.This feature article summarizes the structure and properties of dopant-free polymeric HTM for efficient PSC in recent years,and analyzes the structure-property relationship,proposes the design principle of efficient dopant-free polymeric HTM structure,and looks forward to the future development trend.
