The first transparency conducting layer 120 is coated on the surface of the first transparent base 110; The second transparency conducting layer 150 is overlying on the surface of this second transparent base 140.Wherein, the first transparency conducting layer 120 and the second transparency conducting layer 150 are played the part of the role of conductive electrode in the electrochromic window assemblies 100 with composite electrochromic material, provide the variable color process required electric current, therefore must adopt the transparent conductive material that has high penetration and high electrical conductivity concurrently.Therefore in the present invention, this transparency conducting layer is selected from one of indium oxide WU (Indium Tin Oxide, ITO), aluminum zinc oxide (Aluminum Zinc Oxide, AZO), fluorine doped tin oxide film (Fluorine TinOxide, FTO).Preferably, again due to fluorine doped tin oxide film (FTO) acid and alkali-resistance, heat-resisting, moisture-proof and the film forming raw material is cheap and production cost is low, therefore, use in the present invention the fluorine doped tin oxide film.In addition, the deposition process of the first transparency conducting layer 120 and the second transparency conducting layer 150 system is selected from one of sputtering method, vapour deposition method, electrochemical plating, chemical vapour deposition technique, sol-gel process, spraying cracking process, infusion process, electrochemical process, and the thickness of film forming be 50 how rice to 300 how between rice.
This electrochromic layer 130 is coated on the surface of the first transparency conducting layer 120.Wherein, in electrochromic material, the advantages such as cost of manufacture is low, reaction velocity is fast though organic material has, high optical property and color variation, but still there are many shortcomings to overcome, as not enough in chemical stability, fiduciary level is not good, unstable to the UV ray, and and the transparency electrode tack low etc., in comparison, develop the electrochromism system with inorganic material and have higher feasibility.In view of this, electrochromic layer 130 of the present invention all was comprised of an inorganic material with assisting electrochromic layer 160.Wherein, electrochromic layer 130 is selected from one of tungsten oxide, molybdena, titanium dioxide, niobium oxide, yttrium oxide usually.Preferably, for attract most attention at present and the electrochromic material of widely research be tungsten oxide, because it has high coloration efficiency (Coloration efficiency), reversibility is good, relative price is low, longest-lived and the advantage such as nontoxic.Tungsten oxide film was found to have electrochromism character in 1969, when its variable color mechanism was positioned at tungsten oxide for applying negative electricity, electronics and kation (or proton) were moved into simultaneously in oxygen tungsten Li, and generate M
