Low‐Coordination Solvation Engineering Enables Efficient and Stable Perovskite Solar Cells
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work introduces a kind of low‐coordination solvent, dimethyl carbonate (DMC), to replace a part of DMSO and DMF. DMC substitutes a part of DMSO to coordinate with PbI2 to change the chemical environment of PbI2. What is more, DMC promotes the formation of the nucleation of α‐FAPbI3 crystals.

Modulating Perovskite Crystallization via Multisite Bonding for Enhanced Solar Cell Performance
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study proposes an innovative multisite bonding strategy to regulate crystallization. By employing bidentate ligands N,N‐diethyl‐1,2‐ethanediamine dihydrochloride (DED) that coordinate with uncoordinated Pb2+ and I− vacancies, while simultaneously forming hydrogen bonds with FA+ ions, this synergistic interaction prolongs the perovskite ...
