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.

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。在汽车上使用动态车窗的经济和环境效益包括通过减少空调负荷和加强光/热管理来增加每加仑汽油行驶里程。用动态天窗玻璃取代标准的汽车天窗玻璃，将在夏季将燃油效率提高每加仑3英里。如果一辆汽车中的所有玻璃都被动态玻璃取代，那么影响将会更大，导致每天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解决方案处理技术来创造独特的快速开关电致变色层。目前的动态窗口技术由于成本较高，尚未发挥其市场潜力。由于技术限制，目前的动态窗产品只能用于天窗应用，因此没有用于侧窗、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可实现快速切换、高对比度和低生产成本，这将使智能车窗在广泛的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得到进一步改进，并扩大到具有商业意义的尺寸原型。与目前市场上或处于高级开发阶段的智能窗产品相比，新的智能窗的成本将降低3-4倍。这些新型电致变色器件将在第二阶段研究结束时进行彻底的表征，并确定其长期可靠性。在第二阶段结束时，将建造适合安装在汽车天窗和/或侧窗的快速开关电致变色汽车玻璃原型。
