Functional passivators are conventionally utilized in modifying the crystallization properties of perovskites to minimize the non‐radiative recombination losses in perovskite light‐emitting diodes (PeLEDs). However, the weak anchor ability of some commonly adopted molecules has limited passivation ability to perovskites and even may desorb from the passivated defects in a short period of time, which...
Efficient Light‐Emitting Diodes
In article number 2205336, Yue‐Min Xie, You‐Yong Li, Man‐Keung Fung, and co‐workers introduce a novel multidentate molecule (Formamidine Sulfinic Acid, FSA) to heal perovskite defects, where the intense bonding strength of the S≐O and –NH2 groups of the multidentate molecule to the undercoordinated Pb defects can effectively facilitate the passivation of the perovskites,...
