In this study, we present an all-solid-state electrochromic device (ECD) that eliminates the need for hard-to-obtain materials and conventional liquid/gel electrolytes. Using a cost-effective and industrially scalable spray coating technique, we developed an ECD containing a layer of zinc oxide nanorods (ZnOnano) synthesized via a simple solochemical route. The device configuration includes a preformed Al-coated glass substrate, acting as a counter electrode, within a glass/Al/ZnOnano/PEDOT:PSS architecture. The device exhibits reversible switching between light blue and dark blue states upon application of −1.2 V and +2.8 V, respectively, with a significant difference in transmittance between bleached and colored states in the visible-NIR spectrum, featuring a high coloration efficiency of 275.62 cm2/C at 600 nm. The response times required for both coloring and bleaching states were 9.92 s and 7.51 s, respectively, for a sample with an active area of 5.5 × 2.5 cm2. Regarding the electrochemical stability of the ZnO-based ECD, the transmittance modulation reached around 8.01% at 600 nm after 12,800 s, following initial variations observed during the first 10 cycles. These results represent significant progress in electrochromic technology, offering a sustainable and efficient alternative to traditional ECDs. The use of economical fabrication techniques and the exclusion of critical materials highlight the potential for widespread industrial adoption of this novel ECD design.

纳米结构 ZnO 基固态电致变色器件的制备与性能评价
在这项研究中,我们提出了一种全固态电致变色器件 (ECD),它消除了对难以获得的材料和传统液体/凝胶电解质的需求。使用一种经济高效且工业可扩展的喷涂技术,我们开发了一种 ECD,其中包含一层通过简单的单一化学路线合成的氧化锌纳米棒 (ZnO纳米)。该器件配置包括一个预制的 Al 涂层玻璃基板,在玻璃/Al/ZnO纳米/PEDOT:PSS 架构中充当对电极。该器件在施加 -1.2 V 和 +2.8 V 电压时分别在浅蓝色和深蓝色状态之间表现出可逆切换,在可见光-NIR 光谱中漂白状态和有色状态之间的透射率存在显着差异,在 600 nm 处具有 275.62 cm2/C 的高着色效率。对于有效面积为 5.5 × 2.5 cm2 的样品,着色和漂白状态所需的响应时间分别为 9.92 秒和 7.51 秒。关于基于 ZnO 的 ECD 的电化学稳定性,在前 10 个循环中观察到初始变化后,12,800 s 后,透射率调制在 600 nm 处达到约 8.01%。这些结果代表了电致变色技术的重大进步,为传统 ECD 提供了一种可持续且高效的替代方案。使用经济的制造技术和排除关键材料突出了这种新颖的 ECD 设计在工业上广泛采用的潜力。
