1F-PTAA, or poly(bis(4-phenyl)(4-fluoro-2-methylphenyl)amine, is a mono-fluorinated poly(triaryl)amine which is used as a hole transporting layer (HTL) for perovskite and polymer solar cells.

With the substitution of the methyl to fluorine on the 4-postion, the HOMO energy level is significantly lowered from 5.14 eV to 5.52 eV, which is essential to increase the open voltage (VOC) thus to improve the device efficiency. Fluorination of PTAA also drastically improves device operating lifetime, moisture and thermal stress stability. 1F-PTAA is therefore considered a great alternative as a hole transporting layer material for PTAA and Spiro-OMeTAD.

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.

Perovskite solar cells (PSCs) with hexyltrimethylammounium bromide (HTAB) cast perovskite quantum wells (PQWs) and 1F-PTAA as HTL demonstrated efficiencies exceeding 22% along with significantly improved device stability [2]
