Xiaobo Yin 报告：Controlling Thermal Radiation for Large Scale Energy Applications
报告人：Xiaobo Yin（University of Colorado Boulder）
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 and air conditioning is poised to increase dramatically over the next several decades driven by population, climate and economics. In this talk, I will give an overview on our research progress and, more specifically, present our recent development on thermal radiation control for large scale radiative cooling applications. We demonstrated the scalable manufactured micro-optical composite with extreme light-material interaction provides a 24/7 continuous cooling power of 110 W/m2 without consuming electricity or water.
