Solar energy is considered the most promising renewable energy source. Solar cells can harvest and convert solar energy into electrical energy, which needs to be stored as chemical energy, thereby realizing a balanced supply and demand for energy. As energy storage devices for this purpose, newly developed photo-enhanced rechargeable metal batteries, through the internal integration of photovoltaic technology and high-energy-density metal batteries in a single device, can simplify device configuration, lower costs, and reduce external energy loss. This review focuses on recent progress regarding the working principles, device architectures, and performances of various closed-type and open-type photo-enhanced rechargeable devices based on metal batteries, including Li/Zn-ion, Li-S, and Li/Zn-I 2 , and Li/Zn-O 2 /air, Li-CO 2 , and Na-O 2 batteries. In addition to provide a fundamental understanding of photo-enhanced rechargeable devices, key challenges and possible strategies are also discussed. Finally, some perspectives are provided for further enhancing the overall performance of the proposed devices.

Hydrogen Evolution Reaction In article number 2200434, Shude Liu, Yusuke Yamauchi, Junlei Qi and co‐workers propose a vacancy‐driven strategy for filling Pt into Ni‐vacancies to boost hydrogen evolution reaction activity. The Pt atoms filling into the Ni vacancies subsequently combine with additional O vacancies to tune the electronic structure of surrounding Ni sites, leading to a superior mass activity.
