Abstract: Micro/nano-structured materials offer significantly new opportunities for high efficiency devices and systems for energy harvesting, conversion and storage. Fundamental understanding at the small scale enables us to design structures and materials with unprecedented performances. However, there is a tremendous gap between the proof-of-principle demonstration at small scale and the intrinsically large scale real-world thermal and energy systems. As one example, energy use for cooling is poised to increase dramatically over the next several decades. In this talk, I will give an overview on our research and, more specifically, present our recent development on thermal radiation control for large scale cooling applications. We demonstrated the scalable manufactured hybrid glass-polymer composite with extreme light-matter interactions provides a 24/7 continuous cooling power of 110 W/m2 without consuming electricity or water.
