Fluoro-PTAA

Description

Poly[bis(4-phenyl)(4-fluoro-2-methylphenyl)amine is one of the family members of
poly(triaryl)amine, closely related to PTAA but with a deeper HOMO energy level of −5.52
eV (vs −5.14 eV for PTAA).

F-PTAA as HTL in perovskite solar cells achieving high power conversion efficiencies (PCE). F-PTAA displays a deeper HOMO level than PTAA, allowing to fine tune work functions of photovoltaic systems.
