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.

该赠款为数值工具和纳米制造工艺的开发提供资金，以表征硅薄膜上纳米球涂层的结构-工艺-性能关系。这些涂层不仅有可能在不引入额外表面复合的情况下提高太阳能效率，而且还可以减少制造工艺和成本。开发的数值工具将在考虑有序和无序结构的同时确定提高效率的最佳结构。将对最佳结构进行详细模拟，以确定散射和回音壁模式的作用，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、廉价的旋涂方法将用于了解如何将纳米球涂层组装到硅薄膜光伏器件上。 制造的样品将在结构、光学和电子方面进行表征，以验证模拟。这项研究的结果将导致下一代太阳能电池设计的改进。这也可能对其他利用回音壁模式的纳米光子应用产生深远的影响，例如光学滤波器和生物传感器。预计它将在太阳能电池、拓扑优化和纳米制造领域产生广泛的影响。 该项目还将通过开源软件开发、引入各种教育模块以及参与皮特多样性办公室的 INVESTING NOW 夏季计划来教育和推广下一代工程师。
