Photographic working principle of light energy storage

What are photo-assisted energy storage devices?

Recently, photo-assisted energy storage devices, especially photo-assisted rechargeable metal batteries, are rapidly developed owing to the ability to efficiently convert and store solar energy and the simple configuration, as well as the fact that conventional Li/Zn-ion batteries are widely commercialized.

Can photo-assisted batteries be used for solar energy storage?

Photo-assisted batteries can augment the electrochemical capability of rechargeable batteries and provide a novel approach for solar energy storage. Different from conventional energy storage devices, photo-assisted batteries convert solar energy into electrical energy directly and store it as chemical energy.

Do light-assisted energy storage devices have a bottleneck?

After the detailed demonstration of some photo-assisted energy storage devices examples, the bottleneck of such light-assisted energy storage devices is discussed and the prospects of the light-assisted rechargeable devices are further outlined. The authors declare no conflict of interest.

How do molecular photoisomers store energy?

Storing energy with molecular photoisomers Some molecular photoisomers can be isomerized to a metastable high-energy state by exposure to light. These molecules can then be thermally or catalytically converted back to their initial state, releasing heat in the process.

What are light-assisted energy storage devices?

Light-assisted energy storage devices thus provide a potential way to utilize sunlight at a large scale that is both affordable and limitless.

What is a photo-assisted rechargeable battery?

A photo-assisted rechargeable battery typically comprises two parts: one for solar energy capture and conversion, and the other for energy storage. In the early stages, photo-assisted battery often consisted of a photovoltaic device and an energy storage battery connected by metal wires.
