The University of Notre Dame described a quantum-computing-assisted window coating on November 29, 2022. Researchers combined computation and machine learning to choose the arrangement of ultrathin layers for a transparent radiative cooler.
Following that design process, the team fabricated a coating using silica, alumina and titanium oxide on glass, topped with a polymer. The university reported a 1.2-micrometre coating and an experimentally demonstrated cooling effect.
The intended combination was visible-light transmission, rejection of other incoming solar wavelengths and outward thermal emission. The research involved collaboration with Kyung Hee University in South Korea and appeared in ACS Energy Letters.
The university’s projected cooling-cost reduction is not presented here as a measured household saving. This was a research coating, with no retail installation programme established by the announcement.
