Mitigating Stress‐Induced Nonphotoactive Phase Transition Through Sodium Sulfonate Engineering for Stable and Efficient Perovskite Solar Cells

ABSTRACT Formamidinium lead triiodide (FAPbI 3 ) perovskite solar cells (PSCs) have attracted significant attention due to their outstanding optoelectronic properties. However, their long‐term stability remains limited by lattice strain‐induced transition from the photoactive α‐p...
