Abstract Hydrogen generation via artificial photosynthesis paves a promising way to remit the ever-increasing energy crisis and deteriorative environmental issues. Among all the materials utilized for solar hydrogen production, perovskite has emerged as a rising star due to its superior optoelectronic properties. This manuscript aims to provide a comprehensive review summarizing the recent inspiring advancements on perovskite-based solar hydrogen production systems, including the particulate photocatalysis, photoelectrochemical cells, and photovoltaic-electrocatalytic cells. We start with a brief introduction of the advantages of perovskites for solar hydrogen production and the basic principles of the three most prominent solar hydrogen production systems. The representative progresses in this field are then detailed with a special emphasis on the strategies to improve the efficiency and the stability of the systems. Finally, challenges and opportunities for the further development of the PVK-based solar hydrogen production systems are presented with perspective given on outlook, performance, cost and stability.
