Artificial photosynthesis has attracted increasing attention due to recent environmental and energy concerns. Metal halide perovskites (MHPs) demonstrating excellent optoelectronic properties have currently emerged as novel and efficient photocatalytic materials. In this Minireview, we first briefly introduce the structural uniqueness of MHPs that are responsible for the photo-induced charge separation and charge migration properties, and further summarize the important and necessary photophysical and photochemical aspects of MHPs towards photoredox catalysis. Subsequently, the applications of MHPs for solar energy harvesting and photocatalytic conversion, i.e. H 2 evolution, CO 2 reduction, degradation of organic pollutants, and a particular emphasis on photoredox organic synthesis are extensively demonstrated with a focus on the strategies for improving the performance (e.g., selectivity, activity, stability, recyclability and environmental compatibility) of these MHPs-based photocatalysis systems. We conclude by detailing the existing challenges and prospects on the future development of MHPs-based materials toward photoredox catalysis applications.
