Ternary Solvent Engineering In article number 2300604, Islam, Jesuraj, Ryu and co-workers demonstrate a way to control defects voids by ternary solvent engineering. The power conversion efficiency (PCE) with the increased over 20% uniform perovskite morphology minimal defects. Additionally, engineering could be beneficial from an industrial perspective for achieving stable large-area devices.
