PTAA as Efficient Hole Transport Materials in Perovskite Solar Cells: A Review

Perovskite solar cells (PSCs) with a power conversion efficiency (PCE) overpassing 25% have proved to be the most promising competitor for the next‐generation photovoltaic technology. Massive efforts are devoted to the improvement of the performance and stability of PSCs, whereas the hole transport layer (HTL) has attracted significant interest. Among diverse hole transport materials, poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine (PTAA) is one of the most promising candidates due to its ease of fabrication, transparency to visible light, mechanical flexibility, conductivity, and stability. Over the past few years, there has been an increasing amount of research using PTAA as the HTL first in n–i–p and then in…
