Photothermal energy storage power generation system diagram

Why do photothermal catalytic systems have a certain heat storage capacity?

The photothermal catalytic system has a certain heat storage capacity because it’s a solid-liquid phase system including liquid water. In STHET, TEG can recycle the scattered light and therefore enhances the photothermal effect.

What are photothermal conversions of solar energy?

Then, the state-of-the-art progress for photothermal conversions of solar energy is introduced in detail, mainly including photothermal water evaporation and desalination, photothermal catalysis, photothermal electric power generation, photothermal bacterial killing, photothermal sensors, and photothermal deicing.

How efficient is photothermal power generation?

Although photothermal electric power generation can show a solar-to-electricity conversion efficiency exceeding 7% under 38 Sun, its conversion efficiency remains very low under low concentration solar intensity, such as 1 Sun or ambient conditions.

Can a novel integrated system achieve photothermal catalytic hydrogen production?

3. Conclusion In summary, a novel integrated system (STHET) is firstly proposed to achieve photothermal catalytic hydrogen production coupled with low-grade waste heat utilization by flexible TEGs and thermal storage capacity of liquid phase system for continuous power generation in the dark.

What is solar to hydrogen-electricity and thermal storage system (sthet)?

Solar to hydrogen-electricity and thermal storage system (STHET) is proposed. Hydrogen production in STHET is improved by recycling scattered light. Low-grade waste heat is converted into electrical energy by flexible TEGs. STHET can achieve continuous power generation by self-thermal storage capability.

Can photothermal absorbers generate thermoelectric power?

The generation of thermoelectric power at the interface of the photothermal absorbers and the bulk water has been reported (Figure 19 a). (459) A shape-conforming 3D organic sponge is fabricated for solar evaporation and integrated with thermoelectric modules for electricity generation.
