Поли [бис (4-фенил) (2,4,6-триметилфенил) амин]

Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA), 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 has been reported that the use of PTAA can?substantially improve the open-circuit voltage (VOC) and fill factor (FF) of the cells. Perovskite solar cells based on the use of the hole-transporting materials?exhibit a short-circuit current density JSC of 16.5 mA/cm2,?VOC of 0.997 V and FF?of 0.727.

PTAA can be coated as a substrate material which is used for the transportation of hole in the fabrication of many devices like perovskite solar cells, polymeric light emitting diodes and organic field effect transistors.

PTAA, poly(triaryl amine), semiconductor is an organic p-type semiconductor with hole mobilities of 10^?3?up to 10^?2?cm²?V^?1?s^?1 which results in a high carrier mobility. It is a stable glassy polymer and has good ionization potential for thick film diodes.
