EAPSI: Optimizing the Performance of Perovskite-Silicon Tandem Solar Cells

这项工作的目标是将下一代钙钛矿型薄膜光伏与商业上可用的硅光伏与改进的隧道结集成在一起。这项研究将与澳大利亚墨尔本莫纳什大学的乌多·巴赫博士合作进行。巴赫在钙钛矿材料方面的专业知识，特别是针对透明串联器件的专业知识，将使PI在这个为期8周的计划中极大地发展光伏器件。低成本、无处不在、环境可持续的高效太阳能电池可能会改变我们生活的世界。除了提供获得高效、可持续能源设备的机会外，该奖项还提供了在具有社会意义的技术中整合研究和教育的机会。PI在钙钛矿型光伏方面的知识和背景，以及巴赫集团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学院计划之后继续进行，PI和他的论文项目将优化隧道结，巴赫团队将优化透明钙钛矿层。硅组件将由Suniva®，Inc.首席技术官Ajeet Rohatgi博士提供。Rohatgi博士利用他在大学光伏研究和教育卓越中心的工作产生的独特技术，将Suniva定位为研究、开发和制造高效率、低成本晶体硅电池的美国领先者。在佐治亚理工学院S电子与纳米技术洁净室，上下亚电池之间的先进电气互连层将被沉积。然后是钙钛矿型光伏组件，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设备架构和材料的优化效率，以实现更高的整体效率。该奖项根据东亚和太平洋夏季学院计划，支持一名美国研究生的暑期研究，由NSF和澳大利亚科学院联合资助。

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.
