Characterization and coloration efficiency studies using cyclicvoltammetry and chronocoulometric methods on TiO2 doped WO3 nanocrystalline thin films

Dual-Functional Electrochromic Smart Window Using WO3·H2O-rGO Nanocomposite Ink Spray-Coated on a Low-Cost Hybrid Electrode

“…Besides oxygen-deficient WO 3 , WO 3 hydrates are also known to offer high charge kinetics and electronic conductivity, which provide high cycling stability and improved optical modulation. − Intercalated H 2 O tends to lower the diffusion barrier for the positive ions during electrochemical reactions, thereby releasing the lattice stress arising from electrostatic repulsion . Although WO 3 is well-known as an electrochromic material, there have been continued efforts in the literature to enhance its properties in both amorphous and crystalline forms by doping it with other functional materials , or by making composites. , Doping WO 3 with Mo, Nb, Ti, Au, Ag, and Ni and compositing with Nb 2 O 5 , TiO 2 , SnO 2 , CNTs, and rGO (reduced graphene oxide) is popular. An attractive choice as a composite material is graphene (or rGO), which has received little attention in the context of electrochromic device technology, perhaps due to the conflicting issues with the ingredients.…”

Construction of TiO2/WO3/TiO2 double heterojunction films for excellent electrochromic performance

“…The past decades have witnessed rapid development of electrochromic technology [1][2][3][4][5] . Extensive research efforts have been devoted to promoting the application of electrochromism in camouflages, smart windows, heat insulation layers, and automobile rearview mirrors those prevent reflected glare, etc.…”
