Molecularly tailored dual-interface passivation via solvent-free rub-on transfer for efficient and stable perovskite LEDs

Abstract Conventional solution-based passivation methods for perovskite light-emitting diodes (PeLEDs) often introduce secondary defects. A molecularly tailored dual-interface passivation strategy is presented using a solvent-free rub-on transfer method, which enables uniform molecular deposition without inducing secondary defects. Specifically, 4-mercaptopyridine (4-MPy) is applied at the buried interface, and 2-mercaptopyridine (2-MPy) is applied on the perovskite surface.
