Chlorine‐Substituted Graphdiyne In article number 1900241 , Tonggang Jiu and co‐workers introduce chlorine‐substituted graphdiyne into MAPbI 3 ‐based perovskite solar cells to produce a peak efficiency of 20.34% with suppressed J‐V hysteresis, which results from the interaction of derivated graphdiyne and PCBM, to be exact, four types of non‐covalent bonds. These findings suggest that derivated graphdiyne could have potential applications in solar cells and other photoelectric devices.
