这项工作的目的是将下一代钙钛矿薄膜光致发光材料和市售的硅光致发光材料与改性的隧道结集成在一起。这项研究将与澳大利亚墨尔本的莫纳什大学的Udo Bach博士合作进行。巴赫在钙钛矿材料方面的专业知识，特别是透明的串联器件，将使PI能够通过这个为期8周的计划极大地发展光伏器件。低成本、无处不在、环境可持续的高效率太阳能电池可以改变我们生活的世界。除了提供获得高效率，可持续能源设备，该奖项提供了机会，研究和教育的整合技术的社会意义。PI在钙钛矿光致发光方面的知识和背景与Bach Group在串联器件方面的知识和专业知识之间的协同作用增加了及时开发高效器件的可能性。这项工作将在东亚和太平洋夏季研究所计划之后继续进行，PI通过他的论文项目优化隧道结，Bach小组优化透明钙钛矿层。硅组件将由Suniva®，Inc.首席技术官Ajeet Rohatgi博士提供。Rohatgi博士将Suniva定位为美国高效率，低成本晶体硅电池研究，开发和制造的领导者，使用独特的技术，这些技术源于他在大学卓越中心的光伏研究和教育工作。顶部和底部子电池之间的先进电气互连层将沉积在格鲁吉亚理工学院？电子和纳米技术研究所洁净室。其次是钙钛矿光伏组件，将使用巴赫集团开发的技术制造。目前正在使用理论模型来预测各种器件架构和材料的优化效率，以获得更高的整体效率。该奖项是东亚和太平洋夏季研究所计划的一部分，由NSF和澳大利亚科学院共同资助，支持美国研究生的夏季研究。

The objective of this work is to integrate next generation perovskite thin-film photovoltaics and commercially available silicon photovoltaics with a modified tunnel junction. This research will be conducted in collaboration with Dr. Udo Bach at Monash University in Melbourne, Australia. Bach's expertise with perovskite materials, specifically for transparent, tandem devices, will allow the PI to evolve the PV device enormously with this 8-week program. Low-cost, ubiquitous, environmentally sustainable solar cells with high efficiencies could transform the world in which we live. In addition to providing access to high-efficiency, sustainable energy devices, the award provides opportunities for the integration of research and education in technologies of societal significance. The synergy between the PI's knowledge and background on perovskite photovoltaics and the Bach Group's knowledge and expertise on tandem devices increases the likelihood that a high efficiency device will be developed in a timely manner. This work will continue after the East Asia and Pacific Summer Institutes program with the PI optimizing the tunnel junction with his thesis project, and the Bach group optimizing the transparent perovskite layer. The silicon component will be provided by Dr. Ajeet Rohatgi, CTO of Suniva®, Inc. Dr. Rohatgi has positioned Suniva as a U.S. leader in the research, development, and manufacturing of high-efficiency, low-cost crystalline silicon cells using unique technology that spawned from his work at the University Center of Excellence for Photovoltaic Research and Education. The advanced electrical interconnecting layer between the top and bottom subcells will be deposited in Georgia Tech?s Institute for Electronics and Nanotechnology Cleanroom. Followed by the perovskite photovoltaic component, which will be fabricated using techniques developed by the Bach Group. The use of theoretical models to predict optimized efficiencies for various device architectures and materials to attain even higher overall efficiencies is currently underway. This award, under the East Asia and Pacific Summer Institutes program, supports summer research by a U.S. graduate student and is jointly funded by NSF and the Australian Academy of Science.
