CHEMISTRY AND ENERGY

Abstract: Passive Daytime Radiative Coolers (PDRCs) are photonic systems that passively achieve sub-ambient cooling even under direct sunlight. PDRCs consist of an optical layer having high reflectivity in the VIS-NIR range coupled with another optical layer characterized by selective radiation emissivity in the atmosphere transparency window (8-13 μm). PDRCs are a disruptive technology with enormous potential for climate mitigation. The possibility to actively tune their optical response by means of external stimuli, thus reversibly switch their optical response between a radiative-cooling or a thermal-absorbing state, would allow to make the most of the PDRC performances in range of atmospheric and climatic conditions, ultimately making PDRCs suitable as an energy-saving technology under real-world conditions. ARCO project objective is the search and implementation of novel materials and concepts for achieving stimuli-responsive PDRC systems, and the realization of a prototype of active PDRC.
