However, this strategy often fails to simultaneously enhance efficiency and stability, owing to the random crystallization and disordered distribution of the 2D perovskite phase. Herein, phenethylammonium iodide and aluminum oxide (Al\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    ) are employed to regulate the growth of 2D perovskites, forming an ordered interpenetrating alumina\u20132D perovskite structure. This unique architecture not only suppresses surface defects in the perovskite but also establishes an energy\u2010level gradient, thereby improving energy\u2010level alignment and facilitating interfacial charge extraction. Consequently, the hole transport layer\u2010free C\u2010PSCs fabricated under ambient air conditions achieved a power conversion efficiency of 18.1% and a T80 stability of 2500\u2009h, demonstrating the effectiveness of the Al\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    \u20132D perovskite structure in
