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 solar-to-electrochemical energy storage?
Molecular Photoelectrochemical Energy Storage Materials for Coupled Solar Batteries Solar-to-electrochemical energy storage is one of the essential solar energy utilization pathways alongside solar-to-electricity and solar-to-chemical conversion.
Can thermal energy be stored as chemical energy?
Thermal energy from the sun can be stored as chemical energy in a process called solar thermochemical energy storage (TCES). The thermal energy is used to drive a reversible endothermic chemical reaction, storing the energy as chemical potential.
What is thermochemical energy storage (TCES)?
As one of the most potential and appealing technologies for efficiently storing and utilizing renewable solar energy, thermochemical energy storage (TCES) possesses the advantages of high energy storage density, less heat loss, stable chemical properties, and long-duration/distance.
What is Photoelectrochemical Energy Storage (PES)?

Are molecular Photoelectrochemical Energy Storage materials effective?
In contrast, molecular photoelectrochemical energy storage materials are promising for their mechanism of exciton-involved redox reaction that allows for extra energy utilization from hot excitons generated by superbandgap excitation and localized heat after absorption of sub-bandgap photons.
Based on PES materials, the PES devices could realize direct solar-to-electrochemical energy storage, which is fundamentally different from photo (electro)catalytic cells (solar-to-chemical energy conversion) and photovoltaic cells (solar-to-electricity energy conversion).
