New Publication

Aihui and Kang’s work on highly efficient halide perovskite light-emitting diodes via molecular passivation has been published in Angewandte Chemie International Edition. Big congratulations!! Read the story here.

Metal halide perovskites are promising for applications in light‐emitting diodes (LEDs), but still suffer from defects‐mediated nonradiative losses, which represent a major efficiency‐limiting factor in perovskite‐based LEDs (PeLEDs). Reported here is a strategy to synthesize molecular passivators with different anchoring groups for defects passivation. The passivated perovskite thin films exhibit improved optoelectronic properties as well as reduced grain size and surface roughness, thus enable highly efficient PeLEDs with an external quantum efficiency of 15.6 %. Our results provide new fundamental insights into the role of organic molecular passivators in boosting the performance of PeLEDs.
