Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA; CAS no. 1333317-99-9), a family member of poly(triaryl)amine, is an excellent hole-transporting and electron-blocking semiconducting material due to its electron-rich components. It is a popular choice for perovskite solar cell devices, due to its:
- Easy processibility
- Good hole transport and electron blocking qualities
- High thermal stability
- Use in both regular and inverted devices
PTAA from Ossila was used in the high-impact paper (IF 30.85), Multiply Charged Conjugated Polyelectrolytes as a Multifunctional Interlayer for Efficient and Scalable Perovskite Solar Cells, E. Jung et al., Adv. Mater., 2002333 (2020); DOI: 10.1002/adma.202002333.
