Thermal and light solar container efficiency

What is solar-thermal energy storage (STES)?

Among various technologies of solar energy utilization, solar-thermal energy storage (STES) technologies are widely studied to counter the mismatch between supply and energy demand as solar energy is intermittent and weather-dependent 5, 6, 7.

How to improve solar-to-thermal conversion efficiency?

The slow movement of charging interface and low thermal energy storage rate restrict the solar-to-thermal conversion efficiency and cause potential overheating issues. The most common strategy to accelerate the charging rate is enhancing the thermal conductivity of PCMs.

Can optical waveguide enhance solar-thermal energy storage system?

For example, the optical fiber can be coated with heat conducting tube. Thus the heat release of the thermal storage system can be enhanced. In summary, we introduced optical waveguide into solar-thermal energy storage system to enhance the charging rate and solar-thermal energy conversion efficiency.

What are the advantages of solar-thermal charging interface?

This optimization of solar-thermal charging interface avoided the overheating surface of the PCMs and reduced the convection and radiation heat loss greatly. Comparing to traditional surface irradiation mode, this inner-light-supply mode accelerated the charging rate by 123% and the solar thermal efficiency could up to 94.85%.
