Abstract
The present review article is focussed on different types of hole-transporting materials (HTMs) under research over the past few years in the perovskite-based solar cell (PSC) in achieving the goal of higher power conversion efficiency (PCE) and operational stability. There has been a growth spurt of efficiency from 3.8 to 22.1% in the last decade which has attracted researchers and the renewable industry. HTMs are an indispensable part of PSC which affects both efficiency and stability. An overview of different types of HTMs (organic, inorganic, and polymeric) is presented detailing its structure, electrochemical, and physical properties, while highlighting several considerations for making a choice for a new HTM for PSC. The recent progress is shown with PSC’s device architecture, fabrication technique and their respective JV characteristics to help readers understand the challenges surrounding HTM and opportunities to make it highly efficient and stable.
