• Electrochromics is the emerging technology that is used in sunlight control window glazing for buildings, automobiles and it can also control indoor climate through smart windows. Electrochromism is the mutable change in optical properties of an electrochromic material caused by redox reactions due to the application of voltage. Easy intercalating the H + ions on a dense electrochromic material (WO3) is the most important parameter as far as the reaction kinetics is concerned. The goal of our work is to improve the electrochemical response of electrochromic material by constructing nano-pillars rather than using dense electrochromic materials. Electrochemical performance of both the dense (planar) and porus (nano pillars) structures were simulated and experimentally proved with a systematic discussion in the present work. It is proven and shown here the increase in the electrochemical kinetics through easy diffusion of ions into the nanostructured electrochromic material. •Simulation of tungsten oxide thin films using COMSOL Multi Physics.•Experimental of tungsten oxide thin films deposited using DC Magnetron Sputtering.•Comparison of simulation and experimental data.•The increase in the intercalation/de-intercalation of H+ ions suggest that, the vertically aligned nanorods covered with WO3 films structure.
