A Janus Smart Window for Temperature-Adaptive Radiative Cooling and Adjustable Solar Transmittance.

ABSTRACT: The advancement of sophisticated smart windows exhibiting superior thermoregulation capabilities in both solar spectrum and long-wave infrared range maintains a prominent objective for researchers in this field. In this study, a Janus window is proposed and prepared based on polymer-stabilized liquid-crystal films/thermochromic materials. It can achieve switchable front long-wave infrared emissivity (ε_Front) and solar modulation ability (ΔT_sol) through dynamic flipping, making it suitable for different seasonal energy-saving requirements. Outdoor experiments show that under daytime illumination, the indoor temperature decreases by 8 °C, and the nighttime temperature drops by 5 °C. MATLAB simulation calculations indicate that the daytime cooling power is 93 W m^-2<
