Abstract Most strategies only focus on passivating dynamic defects the surfaces of perovskite films or addressing Pb leakage issues separately, lacking comprehensive solutions. In view this, photochromic compound 1,3,3‐trimethylindolinonaphthospirooxazine (SO) and its photoisomerization product (MC) are innovatively introduced into inorganic solar cells (IPSCs). Under light irradiation, distinctive transformation characteristics photoisomeric molecules leveraged to effectively continuously passivate defects. Meanwhile, ring‐opening MC structure provides two anchoring sites, which form a stable chelating ring with undercoordinated 2+ , thereby mitigating risk leakage. Both theoretical analyses experimental findings indicate that expose more active sites due their open molecular under illumination, thus tightly binding ions (I − ) in films. The passivation treatment exhibits an impressive power conversion efficiency (PCE) 22.04%, while also improving hydrophobicity, UV resistance, biocompatibility This approach not presents new perspective for boosting performance stability IPSCs but takes important step toward promoting development environmental friendliness sustainability.

Comprehensive Summary Monolithic perovskite/organic tandem solar cells (TSCs) have gained significant attention due to their easy device integration and the potential surpass Shockley–Queisser limit of single‐junction cells. However, surfaces wide‐bandgap perovskite films are densely populated with defects, leading severe non‐radiative recombination energy loss. As a consequence, power conversion efficiency (PCE) TSCs lags behind that other TSC counterparts. To address these issues, we designed functional ammonium salt, 4‐(2‐hydroxyethyl)piperazin‐1‐ium iodide (PZOI), comprising piperazine terminated hydroxyl group, which was applied for post‐treating surface. Our findings reveal PZOI reacts consumes residual PbX 2 (X: I or Br) form 2D component, thereby eliminating Pb 0 while group in can also passivate uncoordinated 2+ . Consequently, shallow/deep‐level defect densities 2D/3D film were significantly reduced, an enhanced PCE 18.18% reduced loss 40 meV. Importantly, corresponding achieved remarkable 24.05% operational stability ( T 90 ~500 h).

By coupling with organic cations having desirable functional groups dipole moments, can effectively passivate defects adjust alignment interface levels. Consequently, record V oc approaching 1.3 high power conversion efficiency (PCE) 18.59 % could be achieved 1.78 eV band single‐junction inverted PSC. More importantly, TSC derived this cell demonstrates T 90 lifetime 1000 h operation, presenting most stable reported so far.
