Front Cover: Perovskite Light‐Emitting Electrochemical Cells Employing Electron Injection/Transport Layers of Ionic Transition Metal Complexes (Chem. Eur. J. 71/2021)

A layer of ionic transition metal complex promotes electron injection and transport, resulting in an improved carrier balance of green CsPbBr3 perovskite/iTMC light‐emitting electrochemical cells (LECs). The optimized external quantum efficiency reaches 6.8 %, which is among the highest values repor...

Summary:A layer of ionic transition metal complex promotes electron injection and transport, resulting in an improved carrier balance of green CsPbBr3 perovskite/iTMC light‐emitting electrochemical cells (LECs). The optimized external quantum efficiency reaches 6.8 %, which is among the highest values reported for perovskite LECs so far. More information can be found in the Research Article by C.‐W. Lu, Z.‐P. Yang, H.‐C. Su, et al. (DOI: 10.1002/chem.202103739).
