Abstract [en]

Vanadium-dioxide-based thermochromic thin films and nanoparticle composites can have significant transmittance for visible light, Tlum, while they are able to transmit more near-infrared solar radiation at τ < τc than at τ > τc, where τ denotes temperature and τc ≈ 68 °C. It has been realized for many years that these properties are of principle interest for energy efficient fenestration, but the technology has been slow to mature. This paper summarizes the state-of-the-art and points at the many advances that have been made during recent years. Specifically, we discuss how to use doping to adjust τc to room temperature and to increase Tlum, how to use nanomaterials to enhance the solar energy transmittance modulation and Tlum, and how to prepare nanoparticle composites by sputtering. We also discuss thermochromic light scattering, which is a recently discovered phenomenon.
