Abstract

Photo-assisted rechargeable batteries are an emerging class of bifunctional devices capable of harvesting solar energy and storing it as electrochemical energy. This dual functionality holds particular promise for powering remote electronic systems autonomously, thereby reducing reliance on traditional power infrastructure. Among various approaches, photo-assisted zinc-based batteries offer a compelling solution for mitigating the intermittency of solar energy through direct solar-to-chemical energy conversion and storage. In this study, we present an efficient photo-assisted zinc–iodine aqueous battery by integrating perovskite-based photoelectrode. A key innovation lies in the application of a conductive, carbon-based waterproof layer onto the otherwise moisture-sensitive perovskite film, enabling stable operation of the photoelectrode in aqueous electrolyte for over a week. The successful demonstration of this proof-of-concept device highlights a promising pathway toward the development of practical, durable, and efficient photo-rechargeable battery technologies.
