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. With PTAA as the hole-transport layer (HTL), best results have shown that the incorporation of MAPbBr3 into FAPbI3 stabilizes the perovskite phase of FAPbI3, improving the power conversion efficiency of the solar cell to more than 18% under a standard illumination of 100 milliwatts/cm2 [2]. This makes PTAA the best polymer HTL yet for perovskites. Later on, 20.2% was achieved in 2015 with PTAA as the HTL.Uses
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.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.Check Digit Verification of cas no
The CAS Registry Mumber 1333317-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,3,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 1333317-99:
(9*1)+(8*3)+(7*3)+(6*3)+(5*3)+(4*1)+(3*7)+(2*9)+(1*9)=139
139 % 10 = 9
So 1333317-99-9 is a valid CAS Registry Number.
