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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.Click here for more information.

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.

Polytriarylamine Semiconductors

The development of high-performance conjugated organic molecules and polymers has received widespread attention in industrial and academic research.

Professor Shinar (Iowa State University, USA) summarizes the developments of a variety of sensor configurations based on organic and hybrid electronics, as low-cost, disposable, non-invasive, wearable bioelectronics for healthcare.

Next generation solar cells have the potential to achieve conversion efficiencies beyond the Shockley-Queisser (S-Q) limit while also significantly lowering production costs.
