Organic–inorganic hybrid perovskite solar cells (PSCs) are regarded as a promising next‐generation photovoltaic technology. However, poor device stability limits their commercialization. Carbon‐based inorganic PSCs (C‐IPSCs) can meet stability challenge owing to the absence of organic components. Meanwhile, the hydrophobic carbon materials as hole transport layers and back electrodes simplify fabrication process, decrease costs, and protect devices from moisture erosion. Since the first attempt for C‐IPSCs in 2016, a series of strategies have been proposed to improve device performance, including the fabrication technique optimization, solvent engineering, composition engineering, interface engineering, charge transport layer optimization, and so on, and the power conversion efficiency of C‐IPSCs are rapidly increased from initial 5% to exceeding 15%. In this review, the recent progress of C‐IPSCs is summarized, the existing challenges in this field are discussed, followed by a prospect for future development. The recent progress of carbon‐based inorganic perovskite solar cells in the aspects of efficiency and stability, including the fabrication technique optimization, solvent engineering, composition engineering, interface engineering, as well as the optimization of electron transport layer and carbon electrode, is reviewed, the existing challenges in this field are discussed, and the prospects for further improvement are anticipated.
