Photoelectrochromic Cell and Photovoltaic Self-charging Battery Guan Yingxun1, Guan Wei *2,3, Chen Zhonglin2, Fang Dawei2 (1 Higher Professional Techniques College, China Medical University, Shenyang 110036) (2 The Department of Environmental Science, Liaoning University, Shenyang 110036) (3 Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008) Abstract The photoelectrochromic cell is a new kind of organic-inorganic hybrid chromoic device driven by the photoelectrochemical mechanism. It is self-powered by solar irradiation and can be controlled easily. In this paper, the device structure, the mechanism, the state of the art of the photoelectrochromic cell and photovoltaic self-charging battery are introduced. The possible method of research and development has also been mentioned.
