Hole transport layer plays an important role in extracting and transporting photogenerated holes from the perovskite layer and suppressing back electron in Perovskite solar cell (PSC). It is an important component of high-performance devices. Classic hole transport materials, such as 2,2',7,7'-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene (spiro- OMeTAD), poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA), etc., have high prices and low hole mobility, which limit the large-scale application. In recent years, self-assembled monolayers (SAM) have been widely used as hole transport layers in inverted PSC to improve device performance. SAM molecular structure contains anchoring functional groups, which can form a single molecule film on the substrate. It has the advantages of low material consumption, no need for additives, low parasitic absorption, compatibility with tandem devices, and is conducive to large-scale manufacturing. It has become a research hotspot in the field of perovskite solar cells. In the light of the development of PSC, this review classifies and summarizes the recent studies on SAM-based hole transport layers according to the different anchoring groups in the SAM molecular structure, and analyzes the effects of the molecular structure changes on the molecular properties and device performance. Finally, the development of SAM as a hole transport layer is summarized and prospected.

Key words: perovskite solar cell, hole transporting materials, self-assembled monolayers, photoelectric conversion efficiency, stability
