“…There is a class of bifunctional electrocatalysts which are photoactive. 15,22,23,25,26,29,31,32,34 One such case, is spinel-type Co 3 O 4 which has a direct and indirect band gap in the range 2.2 to 1.35 eV, 15 therefore, it absorbs visible light. Co 3 O 4 was employed as electrocatalyst in the air (cathode) electrode of Zn-air batteries and it was observed that the current produced under illumination was 30% larger than in the dark.…”

Metal-air batteries are considered one of the most promising next-generation energy storage devices owing to their ultrahigh theoretical specific energy. However, sluggish cathode kinetics (O 2 and CO 2 reduction/evolution) result in large overpotentials and low round-trip efficiencies which seriously hinder their practical applications. Utilizing light to drive slow cathode processes has increasingly becoming a promising solution to this issue. Considering the rapid development and emerging issues of this field, this Review summarizes the current understanding of light-assisted metalair batteries in terms of configurations and mechanisms, provides general design strategies and specific examples of photocathodes, systematically discusses the influence of light on batteries, and finally identifies existing gaps and future priorities for the development of practical light-assisted metal-air batteries.

“…[165,166] In order to obtain high conversion efficiency and high durability, photoanode with suitable energy level (energy level matching) needs to be considered when designing integrated photoelectrodes to meet the requirements (light harvesting efficiency and charge separation efficiency) of different devices. [167,168] To this end, we combined the use characteristics of different integrated devices, and carried out detailed analysis and summary from three types of liquid, solid, and gaseous, respectively, to provide a reasonable mechanism analysis for the selection of suitable photoelectrodes.…”

As an emerging solar energy utilization technology, solar redox batteries (SPRBs) combine the superior advantages of photoelectrochemical (PEC) devices and redox batteries and are considered as alternative candidates for large‐scale solar energy capture, conversion, and storage. In this review, a systematic summary from three aspects, including: dye sensitizers, PEC properties, and photoelectronic integrated systems, based on the characteristics of rechargeable batteries and the advantages of photovoltaic technology, is presented. The matching problem of high‐performance dye sensitizers, strategies to improve the performance of photoelectrode PEC, and the working mechanism and structure design of multienergy photoelectronic integrated devices are mainly introduced and analyzed. In particular, the devices and improvement strategies of high‐performance electrode materials are analyzed from the perspective of different photoelectronic integrated devices (liquid‐based and solid‐state‐based). Finally, future perspectives are provided for further improving the performance of SPRBs. This work will open up new prospects for the development of high‐efficiency photoelectronic integrated batteries.
