Additive treatment yields high-performance lead-free perovskite light-emitting diodes

Tin (Sn)-based perovskites are promising for realizing lead-free perovskite light-emitting diodes 1 , 2 , yet achieving high efficiency devices remains a significant challenge due to the presence of high density of defects in Sn perovskites 3 , 4 . The formation of defects in Sn perovskites is still...
