An intelligent electrochromic film with passive radiative cooling and synergistic solar light control capabilities for displays and smart windows

The proposed film has a good light modulation capability within the solar spectrum (Δ T lum = 75.13 and Δ T sol = 66.41), and the maximum cooling power during the day and night reaches 97.63 W m −2 K −1 and 136.24 W m −2 K −1 , respectively.
