Radiative cooling as low-grade energy source: a literature review

Radiative cooling is a technology intended to provide cooling using the sky as a heat sink. This technology has been widely studied since 20th century but its research is scattered all over the literature, requiring of a review to gather all information and a state-of-the-art. In the present article...
