Abstract Rational regulation of Me‐4PACz/perovskite interface has emerged as a significant challenge in the pursuit highly efficient and stable perovskite solar cells (PSCs). Herein, an organometallic molecule aluminum glycinate (AG) that contained amine (‐NH 2 ) hydroxyl (Al‐OH) groups is developed to tailor buried minimize interface‐driven energy losses. The Al‐OH selectively bonded with unanchored O═P‐OH bare NiO‐OH optimize surface morphology levels, while ‐NH group interacted specifically Pb 2+ retard crystallization, passivate Pb‐related defects, release residual stress. These interactions facilitate carrier extraction reduce losses, thereby realizing balanced charge transport. Consequently, AG‐modified narrow bandgap (1.55 eV) PSC demonstrates efficiency 26.74% (certified 26.21%) fill factor 86.65%; wide (1.785 realizes 20.71% champion excellent repeatability. PSCs maintain 91.37%, 91.92%, 92.00% their initial after aging air atmosphere, nitrogen‐filled atmosphere at 85 °C, continuously tracking maximum power‐point under one‐sun illumination (100 mW cm −2 for 1200 h, respectively.

Abstract Considering the high surface defects of polycrystalline perovskite, chemical passivation is effective in reducing defects‐associated carrier losses. However, challenges remain promoting effects without compromising carrier‐extraction yield at perovskite interfaces. In this work, interlayer molecules functionalized with different side groups are rationally designed to investigate correlation between defect‐passivation strength and interfacial dynamics. It revealed that Cl‐grafted impose destructive on structure due its lower electronegativity mismatched spatial configuration. The introduction cyanide (CN) as a group also leads deformation unfavorable hole collection. After molecular optimization, incorporation carbonyl (C═O) (TPA─O) simultaneously promotes carrier‐collection well sufficient defect passivation. As consequence, devices based TPA─O champion PCE 23.25%, along remarkable stability by remaining above 88.5% initial performance after 2544 h storage air. Furthermore, TAP─O enables flexible achieve efficiency 21.81% promising mechanical stability. This work paves way for further improving solar cells.

Abstract Tandem solar cells combining perovskite and silicon have witnessed rapid development in recent years. However, the top cell, utilizing wide‐bandgap as absorbers generally suffer significant open‐circuit voltage ( V OC ) deficit, particularly for inorganic perovskite, which poses a considerable obstacle to enhancing power conversion efficiency (PCE). Here, modulation strategy by using 2,6‐pyridinedicarboxamide (PC), crystallization kinetics of film can be effectively regulated, specifically manifested relatively longer annealing time air, resulting sufficient growth grains. Additionally, PC situ passivate uncoordinated Pb 2+ , suppressing non‐radiative recombination charge carriers. Eventually, record PCE 22.07% is achieved based on n–i–p (IPSCs), also demonstrate highest above 1.34 (1.71 eV bandgap). More importantly, unencapsulated IPSCs show enhanced thermal stability photostability. Furthermore, are applied perovskite/silicon tandem (IPTSCs), 27.27% an impressive 2.024 obtained.
