Název v původním jazyce

High-performance thermochromic YSZ/V0.986 W0.014O2/YSZ coatings for energy-saving smart windows

Popis výsledku v původním jazyce

The reversible semiconductor-to-metal transition of vanadium dioxide (VO_2) makes VO_2-based coatings a promising candidate for thermochromic smart windows, reducing the energy consumption of buildings. We report on a scalable sputter deposition technique for fast preparation of strongly thermochromic YSZ/V_0.986 W_0.014 O_2/YSZ coatings, where YSZ denotes Y-stabilized ZrO_2, on conventional soda-lime glass at a relatively low substrate surface temperature (350 °C) and without any substrate bias voltage. The thermochromic V_0.986 W_0.014 O_2 layers, and the antireflection YSZ layers were deposited using a controlled high-power impulse magnetron sputtering of a single V-W and Zr-Y target, respectively. A coating design utilizing a second-order interference in the YSZ layers was applied to increase both the integral luminous transmittance and the modulation of the solar energy transmittance. We present the phase composition (X-ray diffraction) and microstructure (high-resolution transmission electron microscopy) of the coatings and their optical properties (spectrophotometry and spectroscopic ellipsometry). The results constitute an important step to a cost-effective and high-rate preparation of large-area thermochromic VO_2-based coatings for future smart-window applications.
