Professor Pei and his research team have developed a new wide bandwidth thermochromic smart window coating. This coating provides a fast and simple way to construct smart windows. The coating is opaque at ambient temperature and becomes transparent at elevated temperatures. The transition temperature of the coating can be controlled based on the application needs to be in the range of 25°C-130°C. The all-solid coating has a long cycle life and does not use any metal/metal oxides or liquid crystals so it can be used to modulate light over the entire solar spectrum. This smart window can be used to conserve the hot/cold air within buildings during winter/summer or provide privacy.
