摘要

All-inorganic CsPbBr3 perovskite exhibits significant promise for optoelectronic applications owing to its excellent thermal/phase stability, robust environmental tolerance, and favorable photoelectric properties. This review systematically summarizes recent advances in CsPbBr3 research, with a focus on its fundamental characteristics such as crystal structure and carrier dynamics. We detail key synthesis and preparation strategies—encompassing single-crystal growth, nanocrystal chemical synthesis, and high-quality thin-film fabrication—analyzing the principles and critical parameters of each method. The review then concentrates on CsPbBr3’s application in perovskite solar cells (PSCs), highlighting strategies such as: metal/nonmetal ion doping to modulate lattice and band structure; crystallization optimization and morphology control via multifunctional additives for bulk defect passivation; and advanced interface/surface engineering to suppress nonradiative recombination, optimize energy level alignment, and enhance charge extraction/transfer. This review distinguishes itself by providing a comprehensive and critical analysis that systematically bridges the gap between fundamental material properties, synthesis methodologies, and ultimate device performance of CsPbBr3. A key contribution of this review is the critical benchmarking of these strategies against state-of-the-art devices, revealing their evolution, limitations, and underlying physical mechanisms. This mechanistic and comparative perspective, with a focus on advances post-2020, addresses a gap in the existing literature. Finally, we discuss the key challenges and future research directions for CsPbBr3 materials, aiming to provide a valuable reference for their fundamental study and applied development.
