PTAA, to substantially improve PCE of perovskite solar cells

High quality HTL and EBL semiconducting material

Overview | Specifications | MSDS | Pricing and Options | Literature and Reviews

Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA), CAS number 1333317-99-9, one of the family members 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.
