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.

该小企业创新研究 (SBIR) 第二阶段项目的更广泛影响/商业潜力是通过用动态汽车玻璃替换现有汽车玻璃来改善汽车的光/热控制并提高用户舒适度。 在汽车中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增强光/热管理来增加每加仑行驶的里程。 用动态天窗玻璃替换标准汽车天窗玻璃将使夏季每加仑燃油效率提高 3 英里。 如果汽车中的所有玻璃都替换为动态玻璃，那么影响将会更大，导致石油消耗量每天减少数百万桶。这个小型企业创新研究（SBIR）第二阶段项目将利用经过处理的可扩展解决方案技术来创建独特的快速切换电致变色层。由于成本高昂，当前的动态窗口技术尚未发挥其市场潜力。 由于技术限制，目前的动态车窗产品只能用于天窗应用，并未用于侧窗、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车窗，可实现快速切换、高对比度和低生产成本，将使智能车窗在各种汽车中得到广泛采用。第一阶段研究中开发的新型电致变色层将进一步改进，并扩大到具有商业意义的原型尺寸。与市场上或处于高级开发阶段的当前智能窗户产品相比，新型智能窗户的成本将降低 3-4 倍。 这些新颖的电致变色器件将在第二阶段研究结束时得到彻底的表征，并确定其长期可靠性。第二阶段结束时，将制造出适合安装在汽车天窗和/或侧窗的快速切换电致变色汽车玻璃原型。
