The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to reduce the cost of solar generated electricity by increasing the efficiency of panels and reducing cleaning and maintenance costs. This improvement is created using a nanoscale glass coating that increases transmittance of single side coated solar PV glass and creates an antifogging and self-cleaning surface. These savings increase with photovoltaic device efficiencies as well, so as the next generation of solar cells will see even greater benefit from the proposed innovation. Reducing the cost per watt of solar generated electricity is one of the grand energy challenges and has immense societal and governmental impacts. The proposed project is one component of addressing that challenge. The technical advances made in this project will also be applicable to additional market opportunities in LED lighting and other cutting-edge markets. This Small Business Innovation Research (SBIR) Phase II project investigates the deposition of water-based nanoparticle solutions using industrially scalable methods and results in valuable scientific knowledge that is not currently available in the field. Nanoparticle-based antireflective glass coatings have been presented in both the scientific literature and commercial products. However, most coatings suffer from either high deposition costs, or a trade-off between durability and performance. In this project, methods to increase the durability of a low-cost, high-performance nanoparticle that were developed in the Phase I project are scaled to high throughput and low cost fabrication methods. The process/structure/property relationships of this novel coating will be investigated and lead to new scientific knowledge related to the large-scale deployment of nanoparticle based technologies. The coated glass will be subjected to industry standard reliability and durability tests. The expected outcome of this work is the demonstration of this technology at a pilot level with industry collaborators.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力是通过提高面板的效率并降低清洁和维护成本来降低太阳能发电的成本。这种改进是使用纳米级玻璃涂层创建的，该玻璃涂层增加了单侧涂层太阳能PV玻璃的透射率，并产生了防染色和自我清洁的表面。 这些节省也随着光伏设备的效率而增加，因此，下一代太阳能电池将使所提出的创新受益更大。降低每瓦太阳能发电的成本是巨大的能源挑战之一，并且具有巨大的社会和政府影响。拟议的项目是应对这一挑战的组成部分。该项目中的技术进步也将适用于LED照明和其他尖端市场的其他市场机会。这项小型企业创新研究（SBIR）II期项目使用可扩展的方法研究了水性纳米粒子解决方案的沉积，并导致该领域目前尚不可用的有价值的科学知识。科学文献和商业产品既提出了基于纳米颗粒的抗反射玻璃涂层。但是，大多数涂料都遭受高沉积成本或耐用性和性能之间的权衡。在该项目中，在I期项目中开发的低成本，高性能纳米颗粒的耐用性的方法被缩放到高吞吐量和低成本制造方法。这种新颖涂层的过程/结构/性质关系将进行研究，并导致与基于纳米颗粒的技术的大规模部署有关的新科学知识。涂层玻璃将经过行业标准可靠性和耐用性测试。这项工作的预期结果是该技术在与行业合作者的试点层面上展示。
