From: Continuously variable emission for mechanical deformation induced radiative cooling
a Schematic drawing of the thermal characterization setup used in the thermal performance analysis. Calculated net cooling power of the reconfigurable nanophotonic structure at different strains as a function of its own temperature at nighttime and daytime under 0.5 sun (0.5 × AM 1.5 illumination) and 0.9 sun (0.9 × AM 1.5 illumination) with (b) or without (c) polyethylene (PE) convection shield. Solid curve and dashed curve represent the nanophotonic structure are under 0% strain and 120% strain, respectively. The inset depicts the schematic of the thermal characterization setup under closed environment (b) and open to ambient (c).
