Halide‐Cation Interactions Enable Controlled Crystallization and Defect Minimization in High‐Performance All‐Perovskite Tandems
) and fill factor (FF). When integrated into tandem devices, the treated cells yield remarkable PCEs of 29.2% (Cl-salt) and 29.3% (F-salt), and maintain 87% of the initial PCE after maximum power point tracking (MPP) under 1 sun illumination for 700 h.
