SBIR Phase I: Fast Switching Electrochromic Window

这个小型企业创新研究(SBIR)第一阶段项目将开发可扩展的解决方案处理技术，以创建独特的快速开关电致变色层。新的电致变色层将首先被检查兼容性和性能，然后随后用于构建固态快速开关窗口。对固态电致变色器件的系统表征将确定系统中的哪些组件限制性能。成功制造后，该公司预计将在快速开关速度下实现增强的光传输调制，用于汽车应用。该项目的更广泛的影响/商业潜力将是解决汽车应用，改善汽车的光/热控制，并通过用动态汽车玻璃取代现有的汽车玻璃来提高用户舒适度。在汽车上使用动态车窗的经济和环境效益是显而易见的：通过加强光/热管理减少空调负荷，增加每加仑汽油行驶里程。燃油效率每加仑提高3英里，每天将减少100万桶石油消耗。据估计，用动态天窗玻璃取代标准的汽车天窗玻璃，在夏季将使燃油效率每加仑提高3英里。如果一辆汽车中的所有玻璃都被动态玻璃取代，那么影响将会大得多，从而导致每天减少数百万桶石油消耗。尽管如此，当前的动态窗口技术由于成本较高，尚未发挥其市场潜力。电致变色窗基于创新的材料和器件设计，与目前可用的替代动态窗技术相比，实现了快速切换和高对比度，同时降低了生产成本。这一独特技术的广泛采用不仅将增强动态窗口的市场渗透率，还将建立一个新的性能和成本基准。

This Small Business Innovation Research (SBIR) Phase I project will develop scalable solution processed techniques to create unique fast switching electrochromic layers. The novel electrochromic layers will be initially examined for compatibility and performance then subsequently used to construct solid state fast switching windows. Systematic characterization of the solid state electrochromic device will establish which components in the system limit performance. Upon successful fabrication, the company expects to achieve enhanced light transmission modulation at fast switching speed s for automotive applications.The broader impact/commercial potential of this project will be to address automotive applications in improve light/heat control into the automobile and enhance user comfort by replacing existing automotive glass with dynamic automotive glass. Economic and environmental benefits of using dynamic windows in automotives are clear: increasing miles per gallon by reducing air conditioning load with enhance light/heat management. Increasing fuel efficiency by 3 miles per gallon will decrease oil consumption by one million barrels of oil per day. It is estimated that replacing standard automotive sunroof glass with dynamic sunroof glass will increase fuel efficiency by 3 miles per gallon during summer time. If all the glass in an automobile are replaced with dynamic glass then the impact will be much larger resulting in decrease in oil consumption by several millions of barrels per day. Still, current dynamic window technologies have not reached their market potential due to their high cost. The electrochromic windows are based innovative materials and device designs that achieve fast switching and high contrast while reducing production costs compared to alternate dynamic window technologies available today. Wide scale adoption of this unique technology will not only enhance market penetration for dynamic windows but establish a new benchmark for performance and cost.
