Here, we reveal that mass transfer is one major limiting factor during solution growth of perovskite thin monocrystals. A general approach is developed to overcome synthetic limitation by using a high solute flux system, in which mass diffusion coefficient is improved from 1.7×10^-10 to 5.4×10^-10 m² s^-1 by suppressing monomer aggregation. The generality of this approach is validated by the synthesis of 29 types of perovskite thin monocrystals at 40-90 °C with the growth velocity up to 27.2 μm min^-1. The as-grown perovskite monocrystals deliver a high X-ray sensitivity of 1.74×10⁵ µC Gy^-1 cm^-2 without applied bias. The findings regarding limited mass transfer and high-flux crystallization are crucial towards advancing the preparation and application of perovskite thin monocrystals.Nature communications2390https://www.ebi.ac.uk/biostudies/studies/S-EPMC10944467biostudies-literatureUniversal growth of perovskite thin monocrystals from high solute flux for sensitive self-driven X-ray detection.PMC10944467Peng YZheng YZou CWei ZYuan HHou YWu XFYao YFLiu XYang HGDai SSui XYLiu DZhou HYang SLin MfalseUniversal growth of perovskite thin monocrystals from high solute flux for sensitive self-driven X-ray detection.Metal-halide perovskite thin monocrystals featuring efficient carrier collection and transport capabilities are well suited for radiation detectors, yet their growth in a generic, well-controlled manner remains challenging.
