A Unified Description of Electron-Phonon Coupling and Ion Migration in Metal Halide Perovskites

The remarkable optoelectronic properties of metal halide perovskites are closely linked to their unusually soft and polar chemical bonds that enable both strong electron-phonon interactions and ion migration. Yet these two defining characteristics have largely been treated as independent consequences of the same underl...

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...
