However, increasing bromide content intensifies compositional instability and halide segregation, leading to voltage losses and long\u2010term operational degradation. Emerging evidence indicates that such instability is frequently preconditioned during film formation through crystallization intermediates, rather than merely manifesting as light\u2010induced halide segregation during operation. This review presents an intermediate\u2010centric framework for understanding crystallization in Br\u2010rich mixed\u2010halide perovskites. Crystallization intermediates are defined as emergent states encompassing both coordination\u2010defined species and structural intermediates (e.g., polytypes), governed by the competitive binding of halides, solvents, and additives to Pb\n                    <jats:sup>2+<\/jats:sup>\n                    centers, thereby regulating nucleation kinetics, halide redistribution, and lattice consolidation. Strong Pb\u2013Br interactions restrict the range of kinetically accessible intermediate configurations, promoting halide\u2010segregated growth and kinetically frozen compositional gradients that subsequently appear as defect\u2010rich regions and ion\u2010migration pathways. Recent advances demonstrate that solvent and additive engineering reshape intermediate accessibility and lifetime, enabling stabilization, synchronization, reconstruction, or even elimination of intermediate states. An intermediate\u2010centered perspective on crystallization provides a chemically grounded basis for improving halide homogeneity, defect control, and stability in Br\u2010rich wide\u2010bandgap perovskite photovoltaics.\n
