Tremendous efforts are being made for better utilization of solar energy to produce chemical fuel through environmentally friendly and scalable processing. The halide perovskite (XP) materials are excellent solar energy harvesting materials because of their fascinating electronic and optical properties. The primary concern is the stability and performance of XP materials under photocatalytic reaction conditions. Various materials structure design strategies are being adapted to address the stability issue during the application of XPs for solar-to-chemical fuel generation. In this review, we discuss recent achievements in the efficient utilization of different XPs as photoactive materials in particulate photocatalysis, photoelectrode-based photoelectrocatalysis, and integrated photovoltaic-electrochemical cell systems for the water splitting and CO2 reduction reactions. This paper introduces the researchers to the methods of development of XP materials for photocatalysis and photovoltaic device-enabled photocatalytic applications. It discusses the strategic structural modifications in vogue and the upcoming ones that need to be incorporated for efficiency improvement in the XP-based systems for renewable chemical fuel production.
