N2 - VO2-based thin films exhibit great potential applications in thermochromic smart windows. However, it is still a challenge to synergistically achieve the high luminous transmittance (Tlum) and large solar modulation (ΔTsol). In this paper, antireflective (AR) TiO2/VO2 thin films are designed through optical simulations, and the thin films with optimized film thickness are prepared by magnetron sputtering. The overall performances of the thin films are significantly improved. Compared with single-layer VO2, the Tlum value of the TiO2/VO2 thin film is significantly increased from 29.03% to 46.29% by 59.5%, and the ΔTsol value is increased up to 16.03%. The Tlum and ΔTsol values of the TiO2/VO2/TiO2 sandwiched thin films can be further improved up to 50.49% and 20.11%, respectively, owing to the light interference at the interfaces between the multilayers. The results provide an effective strategy for improving the performance of smart windows.
