Disrupting Solvent Self‐Association via Dipole–Dipole Interactions for Improved Performance of Perovskite Solar Cell
High‐quality perovskite films demand strongly coordinating solvents (SCS, e.g., DMSO, NMP) for crystal growth regulation, yet such solvents often leave residue and induce notorious voids. Prior work elucidated the voids distribution along the vertical direction but cannot explain their lateral dimensions and spatia...
