Abstract

The article focuses on the development of an all-season smart film designed for reversible modulation between radiative cooling and solar heating to enhance building energy conservation and reduce carbon emissions. This multilayer film consists of In₃SbTe₂ (IST), CaF₂, and ZnS on an aluminum substrate, utilizing the nonvolatile phase change of IST to switch between a solar heating mode (high solar absorptance and low infrared emittance) and a radiative cooling mode (low solar absorptance and high infrared emittance). The modulation mechanism is based on Fabry–Pérot resonance and antireflection effects, with the film maintaining effective performance across a wide range of incident angles and enabling multilevel control by varying the crystalline percentage of IST. Quantitative analysis shows the film achieves a solar heating flux of 800 W/m² at 250 K in the amorphous IST state and a radiative cooling flux of 600 W/m² at 330 K in the crystalline IST state, highlighting its potential for practical terrestrial applications.
