Bio-inspired TiO₂ nano-cone antireflection layer for the optical performance improvement of VO₂ thermochromic smart windows.

ABSTRACT: Vanadium dioxide (VO₂) is a promising material for thermochromic glazing. However, VO₂ thermochromic smart windows suffer from several problems that prevent commercialization: low luminous transmittance (T_lum) and low solar modulation ability (ΔT_sol). The solution to these problems can be sought from nature where the evolution of various species has enabled them to survive. Investigations into the morphology of moths eyes has shown that their unique nanostructures provide an excellent antireflection optical layer that helps moths sharply capture the light in each wavelength from a wide angle. Inspired by this mechanism, a VO₂ thermochromic smart window coated with a TiO₂ antireflection layer with a novel nano-cone structure,
