Thermochromic vanadium dioxide film on textured silica substrate for smart window with enhanced visible transmittance and tunable infrared radiation

•Textured substrate was fabricated by nanosphere lithography and reactive ion etching.•Textured VO2 (50 nm) showed ~5% higher transmittance at 555 nm than planar VO2 film.•Luminous transmittance of 63.42% was achieved by 20 nm VO2 film on textured substrate.•The skin comfort-related solar modulation was over 30% between cold and hot states.•Transmittance measurements were well predicted by simulation results.
