Tungsten oxide is a very interesting n-type semiconductor transition metal oxide, which has two different characteristics of electrochromic and photochromic. It has many advantages and potential in the integrated design of photoelectric conversion and energy storage. Therefore, it shows great potential for application in many fields, such as physics, information, materials, chemistry and so on. By building a bridge between electrochromism and photochromism, this project proposes a new integrated device of photoelectric conversion and energy storage based on tungsten oxide electrochromic / photochromic materials, which will provide new ideas and technical support for the future use of green energy. This project will first mainly focus on the characteristics of tungsten oxide dual-functional materials with electrochromic / photochromic effect. The controllable preparation and characteristics of transparent conductive layer and catalytic pair electrode will be discussed. Then we will develop new ionic conductor electrolyte with high ionic conductivity. Finally, we will design and prepare a variety of new photoelectric conversion and energy storage multi-functional integrated devices and reveal the physical mechanism. The applicant published 50 SCI papers related to this project including 16 first/corresponding author papers, which have been cited for more than 800 times. Two of these papers published in Angew. Chem. Int. Ed. were highlighted by Science in a full-page comment. These research results establish solid theoretical and experimental basis for further exploration.
