Poly-TPD (Poly[bis(4-phenyl)(4-butylphenyl)amine]) is an important organic semiconductor material widely used in optoelectronic devices due to its good hole transport properties, tunable energy levels, and excellent film-forming ability

. Its main applications are briefly described below.

 

☀️ Perovskite Solar Cells (PSCs)

In perovskite solar cells, Poly-TPD primarily serves as a hole transport layer (HTL)

. Its HOMO energy level (approximately -5.2 eV) aligns well with the valence band of common perovskite light-absorbing materials, facilitating efficient hole extraction and transport from the perovskite layer while effectively blocking electrons, thereby reducing carrier recombination at the interface and improving device efficiency . For instance, in inverted (p-i-n) structured perovskite solar cells, devices using Poly-TPD as the HTL have achieved an efficiency of up to 21.9%​ . Compared to another commonly used HTL material, PTAA, Poly-TPD offers advantages such as better thermal stability​ and relatively lower cost​ .

 

💡 Quantum Dot Light-Emitting Diodes (QLEDs/QLEDs)

In quantum dot light-emitting diodes, Poly-TPD also functions as a hole transport layer

. Its role is to help balance the injection and transport of electrons and holes within the device, suppress exciton quenching, thereby enhancing the luminescence efficiency and brightness of the device . Early research has successfully created QLEDs capable of emitting high-brightness red, orange, yellow, and green light using Poly-TPD as the HTL .

 

This concise overview covers the core applications of Poly-TPD.
