A multi-mode driven high-performance color-changing window for building environmental protection

In this study, an innovative smart window color-changing is assembled by cathode (Mo^WO3) and anode (TiO2). The color change performance of the window is improved by Mo doping (reversibility increased from 79.1% to 93.6%), and the color change effect of the window can be automatically adjusted by external illumination by TiO2 on the anode. The microstructure and electrochromic behavior were characterized of the cathode. The microstructure was characterized of the anode. At the same time, the feasibility of discoloration of the device under light control is verified.
