Solar-Driven Redox Reactions with Metal Halide Perovskites Heterogeneous Structures

• This paper reviews the fundamentals and research progress of metal halide perovskites (MHPs)-based heterojunctions for solar-driven redox reactions. • A comprehensive summary is presented for the construction of various MHPs-based heterojunctions (e.g., Schottky-junction, type-I/II, Z-scheme, and S-scheme). • The versatile use of MHPs-based heterojunctions in key photocatalytic redox reactions are summarized, including H2 evolution, CO2 reduction, pollutant degradation, and organic synthesis. • The review identifies challenges and prospects for future development in solar-light-driven redox reactions with MHPs-based heterojunctions.
