研究目的
To analyze materials and structures for radiative cooling and suggest future perspectives as a substitute in the cooling industry, aiming for energy-free all-day cooling to mitigate global warming.
研究成果
Metamaterial-based radiative cooling has been proven feasible for energy-free all-day cooling, with various structures achieving temperature reductions below ambient. Random particle-based methods are highlighted as promising for commercialization due to scalability and ease of application, but further research is needed on material optimization, effects of environmental factors, and integration with phase change materials for thermal control.
研究不足
The paper discusses limitations such as the complexity and cost of fabrication for nanophotonic structures, challenges in high humidity environments that close the atmospheric window, and the need for optimization in random particle-based methods for better efficiency and scalability.
