• 説明

  Poly(N,N'-bis-4-butylphenyl-N,N'-bisphenyl)benzidine, also known as polyTPD, is an excellent hole transport layer material used in photovoltaics such as perovskite solar cells. It has also proven polyTPD is a promising candidate HTL in multilayer WPLEDs because its HOMO level 5.2 eV is very close to the work function of the indium tin oxide ITO/PEDOT:PSS anode.

• 使用

  In a recent study of a double-junction Quantum-Dot Light-Emitting Diodes (QD-LEDs), an impressive high quantum efficiency of 42.2% and a high current efficiency of 183.3 cd/A were achieved, which are comparable to those of the best vacuum-deposited tandem organic LEDs. Such high-efficiency devices are achieved by interface engineering of fully optimized single light-emitting units, which improves carriers′ transport/injection balance and suppresses exciton quenching induced by ZnO, and design of an effective interconnecting layer consisting of Poly-TPD mixed poly(9-vinylcarbazole) (PVK)/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate/polyethylenimine ethoxylated-modified ZnO.
  
  Indoor photovoltaics is one of the best sustainable and reliable energy source for low power consumption electronics such as the rapidly growing Internet of Things.
  In another recent study, Perovskite photovoltaic (PPV) cells with a mesoporous PPV (mPPV) structure using typical Spiro-OMeTAD as the hole transport layer (HTL) shows the highest maximum power density (Pmax) of 19.9 μW/cm² under 200 lux and 115.6 μWcm^-2 under 1000 lux (without masking), which is among the best of the indoor PV. When PEDOT:PSS is replaced by Poly-TPD as HTL in the inverted PPV (iPPV) cell, the Pmax under indoor light improves significantly and is comparable to that of the best mesoporous mPPV cell.
