Suppression of non-radiative recombination toward high efficiency perovskite light-emitting diodes

Nickel oxide (NiO) would be an alternative hole transport layer for perovskite light-emitting diodes (PeLEDs). However, the performances of NiO-based PeLEDs are still inferior due to the adverse non-radiative recombination at the interface. Here, a poly(9-vinlycarbazole) (PVK) layer is inserted betw...
