• Applications

  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. ;
