电子可着色窗户可以提高建筑物和汽车的能源效率和舒适度。最近，利用可逆金属电沉积的动态窗已被探索作为电致变色材料的可行替代方案。在这份手稿中，我们首先构建25平方厘米的动态窗口，两个锡掺杂的氧化铟（ITO）的工作电极，金属框架反电极，和含有金属离子的水基电解质。这种布置允许金属电沉积同时发生在两个窗玻璃上，并且增加了切换速度，使得与具有一个工作电极的类似窗相比，器件在10秒内切换到超过30%的透射率，其中具有一个工作电极的类似窗需要30秒才能达到相同的透射率值。具有两个工作电极的窗口在30秒内在透明（600 nm处的透射率为82%）和黑色（600 nm处的透射率为8%）状态之间切换，使其成为该规模上报道的最快的金属基动态窗口之一。第二，我们引发选择性金属电沉积在Pt纳米粒子，附着到ITO基板通过自组装单层（SAM）。通过图案化Pt纳米颗粒的SAM，金属电沉积可以在宏观尺度和微观尺度上进行空间控制。总之，这些结果证明了用于动态窗的可逆金属电沉积架构的多功能性。©作者（S）2019。由ECS发布。这是一篇开放获取的文章，根据知识共享署名4.0许可证（CC BY，http：//creativecommons.org/licenses/by/4.0/）的条款分发，该许可证允许在任何媒体上不受限制地重复使用作品，前提是正确引用原始作品。[DOI：10.1149/2.0961908jes]
Electronically tintable windows increase the energy efficiency and comfort of buildings and automobiles. Recently, dynamic windows harnessing reversible metal electrodeposition have been explored as a viable alternative to electrochromic materials. In this manuscript, we first construct 25 cm2 dynamic windows with two tin-doped indium oxide (ITO) working electrodes, a metal frame counter electrode, and an aqueous-based electrolyte containing metal ions. This arrangement allows metal electrodeposition to occur simultaneously on both window panes and increases switching speed such that devices switch to ∼30% transmission in 10 s compared to analogous windows with one working electrode which take 30 s to reach the same transmission value. Windows with two working electrodes switch between clear (∼82% transmission at 600 nm) and black (∼8% transmission at 600 nm) states within 30 s, making them among the fastest metal-based dynamic windows reported on this scale. Second, we elicit selective metal electrodeposition on Pt nanoparticles that are attached to ITO substrates via a self-assembled monolayer (SAM). By patterning the SAM of Pt nanoparticles, metal electrodeposition can be spatially controlled on both the macroscale and microscale. Taken together, these results demonstrate the versatility of the reversible metal electrodeposition architecture for dynamic windows. © The Author(s) 2019. Published by ECS.
