Abstract Heterojunction perovskite solar cells combine the stability of 2D perovskites and high efficiency 3D perovskites, making them an excellent photovoltaic candidate. While heterojunctions with intermixed or gradient can reduce surface recombination, aggregation phase distribution induce transport losses, thereby limiting device fill factors. Accordingly, a bulk in situ reconstruction (BISR) strategy is proposed to on minim self‐assembled crystal seed, forming heterojunction that runs through entire active layer. This facilitates charge extraction, relieves tensile stress, avoids decomposition grain boundaries. As result, best‐performing show high‐power conversion (PCE) 24.06% 82.9% FF for small‐area (0.105 cm 2 ) superior PCE 19.2% large‐area module (5 × 5 ).

Abstract Precise control over halide perovskite crystallization is pivotal for realizing efficient solar cells. Here, we introduce a strategy utilizing in-situ-formed oxide-based ABX 3 -structured seeds to regulate and growth. Introducing potassium stannate into precursors triggers spontaneous reaction with lead iodide, producing iodide stannate. Potassium effectively passivates defects, while PbSnO (ABX -structured), exhibiting 98% lattice match, acts as template seed. This approach facilitates pre-nucleation cluster formation, preferential grain orientation, the elimination of intermediate-phase processes in films. Incorporating both buried hole transport layers enables single-junction 1.25 eV-bandgap Sn-Pb cells achieve steady-state efficiency 23.12% enhanced stability. Furthermore, all-perovskite tandem devices yield efficiencies 28.12% (two-terminal) 28.81% (four-terminal). versatile templating method also boosts performance 1.77 eV 1.54 cells, underscoring its broad applicability.
