Perovskite solar cells (PSCs) are at the forefront of next-generation solar technology, promising higher efficiencies and lower manufacturing costs compared to traditional silicon-based cells. A critical component enabling these advancements is the Hole Transport Layer (HTL). Among the leading materials for this application, Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine], commonly known as PTAA, stands out for its exceptional properties.

PTAA is a p-type polymer semiconductor renowned for its excellent hole-transporting and electron-blocking capabilities. This dual functionality makes it an ideal candidate for HTLs in PSCs, where it plays a crucial role in efficiently extracting photogenerated holes from the perovskite layer and preventing electrons from reaching the anode. This process directly contributes to a higher power conversion efficiency (PCE) and an improved open-circuit voltage (Voc).

The chemical structure of PTAA, with its electron-rich triarylamine units, provides high thermal stability and an amorphous morphology. This characteristic allows for the formation of smooth, uniform films, which are vital for maintaining good interfacial contact with the perovskite layer and minimizing recombination losses. Unlike some other HTLs that may degrade under operational stress, PTAA offers robust performance, contributing to the overall stability and longevity of the solar device.
