All–Inorganic Perovskite Solar Cells: Defect Regulation and Emerging Applications in Extreme Environments

Abstract All–inorganic perovskite solar cells (PSCs), such as CsPbX 3 , have garnered considerable attention recently, as they exhibit superior thermodynamic and optoelectronic stabilities compared to the organic–inorganic hybrid PSCs. However, the power conversion efficiency (PCE) of CsPbX 3 PSCs is generally lower than that of organic–inorganic hybrid PSCs, as they contain higher defect densities at the interface and within the perovskite light‐absorbing layers, resulting in higher non‐radiative recombination and voltage loss. Consequently, defect regulation has been adopted as an important strategy to improve device performance and stability. This review aims to comprehensively summarize recent progresses…
