Improved performance of thermochromic VO2-based coatings for energy-saving smart windows
Original language description
The paper deals with strongly thermochromic YSZ/W and Sr co-doped VO2/SiO2 coatings, where YSZ is Y-stabilized ZrO2, prepared using a scalable sputter deposition technique on standard soda-lime glass at a low substrate surface temperature of 320 °C and without any substrate bias voltage. The coatings exhibit a transition temperature of 22 °C with an integral luminous transmittance Tlum = 63.7% (below the transition temperature) and 60.7% (above the transition temperature, i.e., no artificial lighting is needed during the day) and a modulation of the solar energy transmittance ΔTsol = 11.2%. Such a combination of properties, together with the low deposition temperature, has not yet been published by other teams for thermochromic VO2-based coatings prepared by a scalable deposition technique compatible with the existing magnetron sputter systems (more than 60%) in glass production lines and large-scale roll-to-roll deposition devices.
