Description

General description

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.

Application

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.
