This Small Business Innovation Research (SBIR) Phase II project seeks to produce and validate the company’s passive cooling thin films to meet specific market requirements such as for refrigerated trailer, inverter, and solar photovoltaic (PV) applications. The product platform may meet the needs of myriad applications and use cases through the development and validation of both transparent and highly reflective/opaque films. The proposed effort may advance the goal of improving cooling technologies by enabling customers in the refrigerated trucking, solar energy, home cooling, and other markets to reduce their greenhouse gas emissions while reducing costs. Examining the annualized refrigerated trucking industry alone, which is valued at $1 billion globally, could reduce greenhouse gas emissions by more than 15 million metric tons of carbon dioxide (CO2) equivalent per year in the U.S.. In addition, application to solar inverters and PV cells may increase the efficiency of renewable power generation. These uses collectively serve to improve the sustainability of multiple industries, with a long-term impact of offsetting the use of fossil fuels and the negative environmental, societal, and health effects tied to them. The intellectual merit of this project is based on exploitation of selective photonic emitters that allow certain wavelengths of light to be emitted above the atmosphere, allowing passive cooling of more than 12.5 degrees C (100 W/m2), with zero energy input and no waste heat generation. Given that the passive cooling is inherent in the microstructure of the film and there is no need for electrical continuity, the product may provide seamless cooling capabilities, even in the unlikely event of mechanical failure of the film. Optimization of the thin films for application-specific use requires the successful completion of three objectives, which are the focus of the Phase II project: 1) investigation of fabrication techniques driving improved film performance compatible with the needs of key market applications, 2) development of application-specific installation methods while maintaining high performance requirements, and 3) development of improved manufacturing processes for production scale-up. Successful accomplishment of these objectives will prime the technology for market entry in a variety of applications, whether new or retrofitted. From a technical perspective, the research and development activities may advance the knowledge of passive radiative cooling systems and how they may be applied to support sustainable innovations in temperature control.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小型企业创新研究 (SBIR) 第二阶段项目旨在生产和验证该公司的被动冷却薄膜，以满足特定的市场需求，例如冷藏拖车、逆变器和太阳能光伏 (PV) 应用。通过透明和高反射/不透明薄膜的开发和验证，该产品平台可以满足无数应用和用例的需求。拟议的努力可以通过使冷藏卡车运输、太阳能、家庭冷却和其他市场的客户在减少温室气体排放的同时降低成本来推进改进冷却技术的目标。仅检查全球价值 10 亿美元的年化冷藏卡车运输行业，就可以在美国每年减少超过 1500 万吨二氧化碳 (CO2) 当量的温室气体排放。此外，太阳能逆变器和光伏电池的应用可能会提高可再生能源发电的效率。这些用途共同有助于提高多个行业的可持续性，其长期影响是抵消化石燃料的使用以及与之相关的负面环境、社会和健康影响。该项目的智力优势基于选择性光子发射器的开发，该发射器允许在大气层上方发射特定波长的光，允许被动冷却超过 12.5 摄氏度（100 W/m2），零能量输入且不产生废热。鉴于被动冷却是薄膜微观结构所固有的，并且不需要电连续性，因此即使在薄膜发生机械故障（不太可能发生）的情况下，该产品也可以提供无缝冷却功能。针对特定应用的薄膜优化需要成功完成三个目标，这是第二阶段项目的重点：1）研究制造技术，以提高薄膜性能，满足关键市场应用的需求；2）开发特定应用的安装方法，同时保持高性能要求；3）开发改进的制造工艺以扩大生产规模。这些目标的成功实现将为各种应用（无论是新应用还是改造应用）的市场进入奠定基础。从技术角度来看，研发活动可能会增进对被动辐射冷却系统的了解，以及如何应用它们来支持温度控制的可持续创新。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
