Perovskite solar cells (PSCs) have been considered the next-generation star of the photovoltaic industry due to their high efficiency and significant application prospects. They are expected to break the Shockley–Quieisser limit of single-junction Si solar cells and promote the industrialization process of perovskites. All-inorganic CsPbBr 3 perovskites have received extensive attention due to their excellent photovoltaic properties and outstanding stability. Our work comprehensively reviews the recent progress of carbon-based CsPbBr 3 PSCs and systematically discusses the modified strategies to achieve high-performance CsPbBr 3 PSCs. Beginning with the CsPbBr 3 film preparation, we summarize the various optimization strategies for perovskite films regarding buried interface modification, additive passivation, and surface defect passivation. Moreover, the modifications of carbon electrodes are summarized and prospectively aimed at obtaining high efficiency. Finally, we discuss the recent advancements and challenges associated with carbon-based all-inorganic CsPbBr 3 PSCs.
