Metal halide perovskites have rapidly emerged as one of the most promising materials for next-generation photovoltaics, owing to their exceptional optoelectronic properties and low manufacturing costs. However, the soft lattice structure and relatively weak ionic bonding of halide perovskites pose significant challenges in simultaneously achieving high power conversion efficiency and long-term operational stability. Our research systematically addresses these critical bottlenecks through a comprehensive approach encompassing materials design, controlled growth, and device-level engineering. To enhance intrinsic stability, we developed a defect suppression strategy based on a reversible “redox shuttle” mechanism[1], which significantly prolongs the operational lifetime of lead halide perovskite materials and devices. Also, we developed an iodine intercalation–decalation strategy to fabricate high-purity, non-alloyed α-FAPbI₃ perovskite films[2]. This composition exhibits intrinsic stability alongside superior optoelectronic performance, presenting a new direction for stable device integration. On the materials synthesis front, we proposed an anion-p interaction strategy to precisely regulate the reaction kinetics, effectively suppressing both nanoscale and atomic-scale defects[3]. Also, we introduced a liquid media annealing method, establishing a highly efficient thermal and chemical environment for film growth that enabled the large-area deposition of high-quality, compositionally homogeneous perovskite films with excellent reproducibility[4]. Finally, we achieved wafer-scale, nondestructive integration of monolayer MoS₂ at the perovskite interface, providing dual-functionality by physically blocking ion migration and chemically passivating interfacial defects[5]. This integration results in photovoltaic devices that combine high efficiency with excellent environmental stability. These innovations across material design, film growth, and device fabrication contribute significantly to the advancement of stable, efficient, and scalable perovskite solar cells, with applicability across the optoelectronic device landscape.
