Crystalline quality is paramount for the performance and stability of perovskite films and devices. By regulating the nucleation and growth processes, it is possible to significantly enhance the crystalline quality. This work introduces a bidirectional synergistic crystallization strategy (BSC strategy) that synchronizes the crystallization kinetics across both the top and bottom surfaces of the perovskite film, thereby enhancing film quality and boosting the efficiency of perovskite solar cells (PSCs). Employing time‐resolved optical characterization techniques, it is demonstrated that the BSC strategy effectively mitigates the dissolution–recrystallization cycle of the perovskite nuclei and grains during annealing, accelerates the evaporation of residual solvents at the bottom of the perovskite film, and suppresses void formation at the buried interface. Depth‐resolved grazing‐incidence wide‐angle scattering analyses further confirm that the BSC strategy improves the crystalline quality of the perovskite film, promotes oriented growth, and minimizes internal residual strains caused by uneven growth dynamics. This approach results in a champion device efficiency of 24.98%, with the low voltage deficit of 360 mV. Moreover, device stability is markedly enhanced, after 1000 h of continuous light exposure, the efficiency remains over 91% of the initial value.

Metal halide perovskite single crystals hold promise for photovoltaics with high efficiency and stability due to their superior optoelectronic properties and weak bulk ion migration. The past several years have witnessed rapid development of single‐crystal perovskite solar cells (PSCs) with efficiency rocketed from 6.5% to 24.3%, however, which still lags behind their polycrystalline counterparts. Moreover, the poor device stability under light illumination is contrary to the high ion migration barrier of perovskite single crystals. The key limiting factors should be the low crystalline quality and high surface defect density of solution‐grown thin single crystals. Under this circumstance, a review paper summarizing the recent progress and challenges will be instructive for future development of this emerging field. In this manuscript, the crystal engineering used to enhance carrier transport and suppress carrier recombination in vertical single‐crystal PSCs will be summarized initially, including crystal growth, component control, surface and interface modification. Subsequently, the application of perovskite single crystals in lateral single‐crystal PSCs will be discussed and compared with the conventionally vertical structure. Finally, the challenges and proposed strategies for the development of single‐crystal PSCs are provided.
