Applications

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/poly3,4-ethylenedioxythiophene:polystyrenesulfonate PEDOT:PSS anode.
As the highest occupied molecular orbital (HOMO) of polyTPD matches well with the VB of the perovskite, which allows for a good transport of holes towards the polyTPD, it is a popular semiconducting material candidate that is used in the HTL of the perovskite structures. And also as the LUMO of polyTPD is significantly closer to vacuum compared with that of the perovskite CB, polyTPD efficiently blocks the flow of electrons.
