The growth of large semiconductor crystals is crucial for advancing modern electronics and optoelectronics. While various crystal techniques have been developed lead halide perovskites, a significant challenge remains: as size increases, performance tends to deteriorate dramatically. This study addresses the inherent limitations perovskite by designing novel strategy near-equilibrium system maintain optimal conditions throughout process. consists three independent units: solution supply unit, recycling which together ensure constant concentration temperature. By systematically optimizing temperature control feeding rates, high-quality FAPbBr3 single crystals, including notable measuring 51 × 45 10 mm3 are successfully produced. demonstrates mobility-lifetime product 2.83 10⁻2 cm2 V⁻¹ an ultralow detection limit 319.22 pGyair, significantly surpassing existing similar size. approach can serve universal platform controlled synthesis all kinds laying foundations their use in optoelectronic applications.
