Aerogel's application in the solar energy sector lies in its excellent thermal insulation properties, specifically addressing the energy efficiency loss problem in solar power equipment.
1. Improved Photothermal Conversion Efficiency: Aerogel's superior thermal insulation properties minimize heat loss, locking in maximum heat generated by the solar absorber and reducing heat dissipation. This is particularly effective in low-temperature or high-wind environments.
2. High-Temperature Stability: The gel can withstand temperatures exceeding 600°C, making it suitable for the high-temperature operating conditions of the absorber in solar thermal power generation systems. It is not susceptible to aging or failure over long-term use.
3. Moisture- and Dust-Resistant, Extending Lifespan: Aerogel's porous, hydrophobic structure blocks moisture and dust from entering photovoltaic panels, minimizing performance degradation caused by moisture, corrosion, and dust accumulation, thereby extending the lifespan of the equipment.
Aerogel for Solar Energy
Aerogel as a super-insulator that traps heat while allowing sunlight through, boosting efficiency in solar thermal collectors for heating and industrial processes, and improving building insulation. By integrating transparent aerogels, researchers create affordable solar devices, like collectors and windows, that overcome heat loss issues, enabling higher temperatures and broader applications, including energy-saving windows and even portable sterilization devices, paving the way for cheaper, more accessible solar tech.
Solar Thermal Collectors: Transparent aerogels significantly reduce heat loss in collectors, allowing them to reach higher temperatures (over 200°C) for industrial heat, water/space heating, and steam generation, often without costly vacuum enclosures or concentrators.
Building Efficiency: Aerogel-filled windows provide superior insulation, making buildings more energy-efficient by blocking heat transfer while maintaining transparency, as noted in MIT Energy Initiative and Phys.org.
Enhanced PV/T Systems: When added to photovoltaic/thermal (PV/T) collectors, aerogel boosts thermal efficiency, increases stagnation temperatures, and provides performance benefits even in cold seasons, improving overall solar energy conversion.
High-Temperature Performance: Specialty aerogels, like refractory or core-shell types, offer stability at high temperatures (up to 700°C), essential for concentrating solar power (CSP) plants.
Affordable & Scalable: Ongoing research focuses on scalable, low-cost production of aerogels for widespread use, moving them closer to mainstream application, according to BuyAerogel.com.
Nanoporous Structure: Aerogels are mostly air, trapped in a solid network (like silica), making them excellent insulators by hindering heat transfer.
Solar Transparency: New aerogels are engineered to be highly transparent to sunlight (over 95%) while effectively blocking infrared (heat) radiation, creating a "greenhouse effect" within collectors.
Heat Management: They balance high solar transmittance with thermal insulation, maximizing heat capture and minimizing losses, which is crucial for efficient energy conversion.
