From: A structural polymer for highly efficient all-day passive radiative cooling

a Calculated net cooling power during the nighttime. b Calculated net cooling power during the daytime. The variable hc is a combined nonradiative heat coefficient. Values of 0, 3, 6, 9, and 12 for hc are used in the calculations. For daytime calculations, 5% solar power absorption is considered.
