SBIR Phase II: Fast Switching Electrochromic Window

这个小型企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力是通过用动态汽车玻璃取代现有的汽车玻璃来改善汽车的光/热控制，并提高用户的舒适度。 在汽车中使用动态窗户的经济和环境效益包括通过减少空调负荷以及增强光/热管理来增加每加仑的英里数。 更换标准的汽车天窗玻璃与动态天窗玻璃将增加燃油效率3英里每加仑在夏季的时间。 如果汽车上的所有玻璃都换成动态玻璃，那么影响将更大，每天可减少数百万桶石油消耗。这个小型企业创新研究（SBIR）第二阶段项目将利用可扩展的溶液处理技术来制造独特的快速开关电致变色层。当前的动态窗口技术由于其高成本而没有达到其市场潜力。 由于技术限制，目前的动态窗产品只能用于天窗应用，因此不能用于侧窗、后玻璃或挡风玻璃。 基于创新材料和设备设计的新型电致变色窗户实现了快速切换，高对比度和低生产成本，将使智能窗户在各种汽车中得到广泛采用。在第一阶段研究期间开发的新型电致变色层将进一步改进并按比例放大到商业上重要的尺寸原型。与目前市场上或处于高级开发阶段的智能窗户产品相比，新的智能窗户的成本将降低3- 4倍。 这些新的电致变色器件将被彻底表征，并在第二阶段研究结束时建立其长期可靠性。在第二阶段结束时，将建立快速切换电致变色汽车玻璃的原型，其适合于安装在汽车中的天窗和/或侧窗。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to 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 automobiles include increase of miles per gallon by reducing air conditioning load with enhance light/heat management. 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 is replaced with dynamic glass then the impact will be much larger, resulting in decrease in oil consumption by several millions of barrels per day.This Small Business Innovation Research (SBIR) Phase II project will utilize scalable solution processed techniques to create unique fast switching electrochromic layers. Current dynamic window technologies have not reached their market potential due to their high cost. Due to technological limitations, current dynamic window products can only be used for sunroof applications as a result there are not being used for side windows, rear glass or windshield. New class of electrochromic windows based on innovative materials and device designs that achieve fast switching, high contrast and low production costs will enable wide spread adoption of smart windows in a broad range of automobiles. The novel electrochromic layers developed during Phase I research will be improved further and scaled up to commercially significant size prototypes. New smart windows will cost 3-4x lower compared to current smart window products on the market or in advanced development stage. These novel electrochromic devices will be thoroughly characterized and their long term reliability established by the end of Phase II research. At the end of Phase II prototypes of fast switching electrochromic automotive glazing will be built that are suitable for installation in a car for sunroof and/or side window.
