Abstract

Inverted perovskite solar cells (PVSCs) have recently made exciting progress, showing high power conversion efficiencies (PCEs) of 25% in single-junction devices and 30.5% in silicon/perovskite tandem devices. The hole transporting material (HTM) in an inverted PVSC plays an important role in determining the device performance, since it not only extracts/transports holes but also affects the growth and crystallization of perovskite film. Currently, polymer and self-assembled monolayer (SAM) have been considered as two types of most promising HTM candidates for inverted PVSCs owing to their high PCEs, high stability and adaptability to large area devices. In this review, recent encouraging progress of high-performance polymer and SAM-based HTMs is systematically reviewed and summarized, including molecular design strategies and the correlation between molecular structure and device performance. We hope this review can inspire further innovative development of HTMs for wide applications in highly efficient and stable inverted PVSCs and the tandem devices.

倒置钙钛矿太阳能电池中高性能有机空穴传输材料的研究进展。

倒置钙钛矿太阳能电池(PVSCs)最近取得了令人兴奋的进展，在单结器件中显示出25%的高功率转换效率(pce)，在硅/钙钛矿串联器件中显示出30.5%的高功率转换效率。在倒置PVSC中，空穴输运材料(HTM)不仅能提取/输运空穴，还能影响钙钛矿薄膜的生长和结晶，对器件性能起着重要的决定作用。目前，聚合物和自组装单层(SAM)由于其高pce、高稳定性和对大面积器件的适应性而被认为是倒立PVSCs最有前途的两种HTM候选材料。本文从分子设计策略、分子结构与器件性能的关系等方面，系统地综述了近年来高性能聚合物和基于sam的HTMs的研究进展。我们希望这一综述能够启发HTMs进一步的创新发展，在高效稳定的倒置PVSCs和串联器件中得到广泛的应用。
