HRTEM directly visualizes a hybrid architecture with amorphous nanoscale surface crystallinity in Y15-AO, while a-Al<sub>2</sub>O<sub>3</sub> shows a single-phase, fully amorphous structure.

In the hybrid structure, the interfacial advantage at Y-modified surfaces/interfaces manifests as strongly exothermic proton incorporation (<em>E</em><sub>bind</sub>=−1.83 eV to −2.07 eV) and a reduced proton migration barrier of 0.56–0.69 eV. These values, which are lower than those in any single-phase counterpart, align with experimentally measured low activation energy of 0.28 eV. The predicted vacancy stabilization strongly agrees with XPS O 1s shifts and the EPR defect-center signal.

To address these challenges, in this work, we designed and demonstrated a more sustainable ternary solvent strategy combining dimethyl sulfoxide (DMSO), acetonitrile (ACN), and 1,3-dimethyl-2-imidazolidinone (DMI). Rheological and morphological studies confirmed that ACN reduces ink viscosity and surface tension while accelerating initial nucleation through its high evaporation rate, facilitating uniform wet-film formation during slot-die coating. Meanwhile, DMI modulates crystallization kinetics by suppressing secondary nucleation through its low vapor pressure and coordination bonding with organic cations, precisely controlling crystal growth. This synergistic effect results in perovskite films with superior morphological characteristics, including larger grain sizes, enhanced thickness, and significantly reduced defect density. Ultimately, the optimized PSCs exhibited a remarkable power conversion efficiency of 20.62 %, with excellent light, thermal, and long-term stability.
