项目摘要

Near-field thermophotovoltaics (NFTPV) promises the conversion of heat to electricity in portable devices with unprecedented efficiency. Such portable converters could recycle the enormous amounts of waste heat in the Canadian (e.g., oil production) and Quebec (e.g., aluminum) industrial sectors and in transport without additional greenhouse gas emissions. This technology is still in its infancy, with only a handful of experimental demonstrations that all achieved low conversion efficiencies or operation at temperatures that are still impractical for heat recycling. Despite such tremendous potential, experimental progress on NFTPV has been relatively slow, arguably from the lack of a truly multidisciplinary approach. For the application to be scalable, the cell should not comprise the highly toxic elements (e.g., Arsenide) that are typically found in group III-V low bandgap cells. Thinned-down germanium Tin PV cells appear as the most promising candidate for fulfilling these criteria. This project brings together unique complementary expertise from the University of Sherbrooke, McGill, and the University of Ottawa to develop a scalable NFTPV device using an innovative process for the detachment of functional GeSn thin film devices from thick Ge substrate.

近场嗜热伏洛尔电（NFTPV）承诺将热量转换为具有前所未有的效率的便携式设备中的电力。这种便携式转换器可以在加拿大（例如石油生产）和魁北克（例如铝制）工业部门以及没有其他温室气体排放的情况下回收大量的废热。这项技术仍处于起步阶段，只有少数实验性的证明都达到了较低的转化效率或在温度仍然不切实际的热回收的温度下的运行。尽管有如此巨大的潜力，但NFTPV的实验进步却相对较慢，这可以说是由于缺乏真正的多学科方法。为了使应用具有可扩展性，该细胞不应包含通常在IIII-V组低带隙细胞中发现的剧毒元素（例如，砷化胺）。变薄的锗锡PV细胞似乎是满足这些标准的最有前途的候选人。该项目汇集了Sherbrooke大学，McGill和渥太华大学的独特互补专业知识，以使用创新的过程来开发可扩展的NFTPV设备，以使功能性GESN薄膜设备脱离厚GE基板。
