摘要:

电致变色技术已被广泛应用在智能窗领域, 但电致变色过程仍需施加外部电压才能完成, 而将电致变色器件与太阳能电池结合构建的电光双调控变色器件则不需外部供电即可实现智能变色调控. 性能优异的变色阴极和光阳极对电光双调控变色器件至关重要, 本文通过水热法结合电沉积法制备了WO3/Ag复合薄膜并研究了其电致变色性能; 通过水热法、 电沉积法结合连续离子层沉积法制备了TiO2/NiO/CdS复合薄膜并研究了其光电转换性能. 将WO3/Ag复合薄膜和TiO2/NiO/CdS复合薄膜分别作为变色阴极和光阳极构建了电光双方式调控的WO3/Ag-CdS/NiO/TiO2变色器件. WO3/Ag-CdS/NiO/TiO2电光双调控变色器件具有较为迅速的光调控响应时间(着色/褪色为82.4 s/135.6 s)和良好的光调制范围(630 nm处为30.4%), 将其作为变色智能窗在建筑、 汽车等领域具有广泛的应用前景.

Abstract:

Electrochromic technology has been widely used in the field of smart windows, but the electrochromic process still needs to be completed by applying an external voltage. The electro-optical dual-control color-changing device constructed by combining electrochromic devices with solar cells does not require external power supply to achieve smart color-changing control. The color-changing cathode and photoanode with excellent performance are very important for electro-optical dual-control color-changing devices. WO3/Ag composite films were prepared by hydrothermal method combined with electrodeposition method and their electrochromic properties were studied. TiO2/NiO/CdS composite films were prepared by hydrothermal method, electrodeposition method combined with continuous ion layer deposition method and their photoelectric conversion properties were studied. Finally, WO3/Ag composite films and TiO2/NiO/CdS composite films were used as color-changing cathode and photoanode, respectively, to construct electro-optical dual-control WO3/Ag-CdS/NiO/TiO2 color-changing devices. The WO3/Ag-CdS/NiO/TiO2 electro-optical dual-control color-changing device has a relatively fast optical-control response time(82.4 s/135.6 s for coloring/bleaching) and a good optical modulation range(30.4% at 630 nm). It has a wide application prospect as a color-changing smart window in the fields of construction and automobile.
