Abstract: The present invention provides a radiative cooling structure that can be fabricated using solution-based processes and offer great IR-selectivity referring to low absorptivity within solar spectrum and high emissivity within the atmosphere transmission window (8-13 microns) for daytime radiative cooling. This structure includes a reflective layer, a ceramic IR-selectively emissive layer and a ceramic emission boosting layer, and the ceramic emission boosting layer is able to boost the overall emissivity of the radiative cooling structure within the atmosphere transmission windows and avoid infrared emission outside the atmosphere transmission window. The IR-selectivity contributes to larger temperature reduction, especially in high humidity area.

Abstract: A thermal radiation microsensor can comprise thermoelectric micro pillars, in which multiple vertically standing thermoelectric micro pillars can act as thermoelectric pairs and mechanical support of an absorption layer. Radiation absorbed by the absorption layer can produce a temperature difference, which drives the thermocouple comprising p-type and n-type micro pillars to output a voltage. Multiple thermocouples can be connected in series to improve the signal output.
