This grant provides funding for the development of numerical tools and nanomanufacturing processes for characterizing the structure-process-performance relationships of nanosphere coatings on silicon thin films. These coatings have the potential to not only enhance solar efficiencies without introducing additional surface recombination, but also reduce manufacturing processes and costs. The developed numerical tools will determine optimal structures for enhanced efficiencies while considering both ordered and disordered structures. Detailed simulations will be performed on optimal structures to determine the role of scattering and whispering gallery modes as well as to determine the angular performance of coated solar cells and evaluate transport characteristics. Scalable, inexpensive spin coating methods will be used to understand how nanosphere coatings may be assembled onto silicon thin film photovoltaics. Manufactured samples will be characterized structurally, optically, and electronically to validate simulations.The results of this research will lead to improvements in the design of next-generation solar cells. This could also have a profound impact on other nanophotonic applications that make use of whispering gallery modes such as optical filters and biosensors. A broad impact is envisioned in the areas of solar cells, topology optimization, and nanomanufacturing. This project will also educate and outreach to next-generation engineers through open source software development, the introduction of various education modules, and involvement with the Pitt Office of Diversity's INVESTING NOW summer program.

该赠款为开发数值工具和纳米制造过程提供了资金，以表征硅薄膜上纳米层涂层的结构过程 - 性能关系。这些涂层不仅有可能在不引入额外的表面重组的情况下提高太阳效率，还可以降低制造过程和成本。开发的数值工具将确定提高效率的最佳结构，同时考虑有序结构和无序结构。将对最佳结构进行详细的模拟，以确定散射和耳语画廊模式的作用，并确定涂层太阳能电池的角度性能并评估传输特性。可扩展的廉价自旋涂层方法将用于了解如何将纳米层涂层组装到硅薄膜光伏上。 制造样品将在结构，光学和电子方式上进行表征以验证模拟。这项研究的结果将改善下一代太阳能电池的设计。这也可能对使用低语画廊模式（例如光学滤镜和生物传感器）产生深远的影响。在太阳能电池，拓扑优化和纳米制造的领域设想了广泛的影响。 该项目还将通过开源软件开发，各种教育模块的引入以及与皮特多样性投资办公室的《现在的夏季计划》一起对下一代工程师进行教育和宣传。
