Electrohydrodynamic-Mediated Molecular Coordination for Stabilizing α-Phase Perovskite Solar Cells
Formamidinium-rich perovskite solar cells (PSCs) have achieved remarkable efficiencies, yet their phase purity is often compromised by the competitive nucleation of the nonperovskite δ-phase during rapid processing. Herein, we demonstrate an electrohydrodynamic (EHD)-mediated chemical strategy to bypass this kinetic...
