Investigation of switchable radiative cooling using real-time transmittance measurement system.

ABSTRACT: Radiative cooling offers a passive and energy-efficient approach to thermal regulation, yet most conventional implementations lack dynamic tunability under varying environmental conditions. Recent advances in switchable radiative cooling materials have shown potential for practical applications, but their transient optical behaviors remain underexplored due to the limitations of conventional spectrophotometers. In this study, a real-time transmittance measurement system is developed that integrates a high-speed spectrometer and a photodiode for dynamic analysis of wet/dry-based switchable radiative cooling films. The system achieves a temporal resolution of 353 ms and ensures measurement reliability through simultaneous monitoring of the light-source intensity. Validation against a commerc
