摘要

Abstract

In the past decade

perovskite solar cells have become a promising candidate in the photovoltaic industry owing to their high power conversion efficiency that surpasses 25%. However

there are certain limitations that have hindered the development and full-scale practical application of these cells

including the high cost and degradation of perovskite caused by the dopants. Hence

there is an urgent need to develop dopant-free hole transport materials (HTMs). In recent years

HTMs based on triphenylamine (TPA-HTMs) are receiving growing interest owing to their high hole mobility

excellent film formation

and suitable energy levels. The literature here covers work relevant to TPA-HTMs in the last five years. They have been classified according to different core types. The correlations between performance and structure are summarized

and the future development trend of TPA-HTMs is highlighted.
