Abstract The interfaces of each layer in perovskite solar cells (PSCs) have a significant impact on the charge transfer and recombination. Especially, interface between hole transport (HTL) p‐i‐n type PSCs significantly affects contact characteristics HTL perovskite, hindering further improvements performance stability. Herein, small molecule 9‐Fluorenylmethoxycarbonyl chloride (9‐YT) is introduced as bridge for PSCs, which enhances interaction self‐assembly molecules (SAMs) perovskite. conjugated backbone 9‐YT can interact with SAM (MeO‐2PACz) by π–π stacking reaction. Moreover, also improves interfacial through strong interactions where carbonyl groups Cl atoms uncoordinated Pb 2+ layer. incorporation demonstrated to markedly enhance extraction at perovskite/hole interface, optimize energy level alignment, mitigate recombination, passivate defects Finally, device treated achieves power conversion efficiency (PCE) 24.82%. At same time, still maintain 92.6% original PCE after long‐term stability test 1200 h.

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).

Abstract Inverted perovskite/organic tandem solar cells (P/O TSCs) suffer from poor long‐term device stability due to halide segregation in organic–inorganic hybrid wide‐band gap (WBG) perovskites, which hinders their practical deployment. Therefore, developing all‐inorganic WBG perovskites for incorporation into P/O TSCs is a promising strategy because of superior under continuous illumination. However, these inorganic also face some critical issues, including rapid crystallization, phase instability, and large energy loss, etc . To tackle two multifunctional additives based on 9,10‐anthraquinone‐2‐sulfonic acid (AQS) are developed regulate the perovskite crystallization by mediating intermediate phases suppress through redox‐shuttle effect. 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.
