What are the photoelectric energy storage materials

What is Photoelectrochemical Energy Storage (PES)?

Newly developed photoelectrochemical energy storage (PES) devices can effectively convert and store solar energy in one two-electrode battery, simplifying the configuration and decreasing the external energy loss.

What is photoelectric storage efficiency (PSE)?

Solar cells serve as energy harvesters, and lithium (Li) secondary batteries or capacitors serve as energy stores in integrated energy modules for self-charging. Within these integrated energy modules, the photoelectric storage efficiency (PSE) is a crucial property for continuous power supply to electronic devices.

What are the different types of photoelectric storage materials?

Here, we provide an overview and analysis of a diverse range of photoelectric storage materials, including organic, inorganic, and organic–inorganic composites. These materials possess a dual functionality, featuring both a photoelectric conversion unit for light absorption and a redox-active unit for photo-generated charge storage.

What are photoelectric devices used for?

Photoelectric devices, including field effect transistors, solar cells, light-emitting diodes, lasers and photodetectors, are widely used in diverse applications such as the renewable clean energy, information storage, miniaturized and intelligent weapons and space defense equipment, etc., which have attracted international attention [1–2].

Can photochemical storage electrodes convert incident solar energy into thermal energy?

Following these principles, more efficient dual-functional photochemical storage electrodes can be developed for solar energy conversion and storage. Materials with photothermal effects convert incident solar energy into thermal energy upon exposure to light.

What are the bottlenecks of Photoelectrochemical Energy storage devices?

Based on the specific discussions of the performance metrics, the bottlenecks of PES devices, including low efficiency and deteriorative stability, are also discussed. Finally, several perspectives of potential strategies to overcome the bottlenecks and realize practical photoelectrochemical energy storage devices are presented.
