PTAA

Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine]-end capped, PTAA, an highly performant hole-transporting, electron-blocking semiconducting polymer that improves open-circuit voltage (Voc), fill factor (FF) and overall performances of various solar cell systems.

PTAA as HTL in perovskite solar cells achieving high power conversion efficiencies (PCE). PTAA displays superior mechanical robustness in terms of cohesion with a cohesion energy (Gc) coefficient over 17 J m−2, the highest reported Gc value among HTL materials.

Polymer for opto-electronic applications.

Various Mw ranges and specific Mw Polyrium batches available to fit your formulations, device fabrication processes and methods (Mw available from 5 kDa to 1000 kDa).

Fluoro-PTAA

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.
