摘要
Recently, CsPbBr3 perovskites have garnered significant attention from researchers due to their exceptional photoluminescence (PL) performance and remarkable stability under harsh, humid conditions—key factors influencing the efficiency and stability of perovskite solar cells (PSCs). Among the various determinants of PSCs performance, the quality of the perovskite absorber
plays a pivotal role. However, challenges remain in achieving large grain sizes, superior crystallinity, reduced grain boundaries, and uniform morphology.
