Fabrication of high flexibility high conversion efficiency heterojunction Si solar cells

该项目的目标是开发一种制造具有高灵活性和高转换效率的晶体硅（Si）基太阳能电池的新技术。该拟议项目是西蒙弗雷泽大学 (SFU) 的 Adachi 博士团队、不列颠哥伦比亚大学 (UBC) 的 O'Leary 博士团队以及工业合作伙伴 Solar Earth Technologies Ltd 的共同努力。潜在的应用包括将柔性太阳能电池纳入 Solar Earth Technologies 的下一代太阳能道路产品、用于下一代移动电子设备的便携式电源以及太阳能充电车辆。太阳能电池将使用西蒙弗雷泽大学的等离子体增强化学气相沉积（PECVD）集群工具，使用薄的低成本太阳能级单晶硅晶圆来制造。必须克服的技术挑战包括开发高通量基板减薄技术、实施有效的光捕获管理策略（旨在以约 10 倍的材料减少最大光吸收）以及高灵活性和高效率光伏原型设备的演示。通过拟议的项目，Solar Earth Technologies Ltd. 将获得新技术，并将其集成到其下一代太阳能道路产品中。此外，由 9 名学生和研究人员组成的团队将获得与半导体器件制造以及光学和电气表征相关的行业相关实践技能，同时接受工业合作伙伴代表的指导和培训。新太阳能电池技术的发展可能会为加拿大人带来新的环保商业产品以及可再生能源和高科技领域的新就业机会。通过该项目的成功完成，将实现开发清洁技术并将实验室研究与商业化和消费者适应周期联系起来的目标，这是加拿大政府的优先事项。

The objective of the proposed project is to develop a new technology for manufacturing crystalline silicon (Si)-based solar cells with high flexibility and high conversion efficiency. The proposed project is a joint effort between Dr. Adachi's team at Simon Fraser University (SFU), Dr. O'Leary's team at The University of British Columbia (UBC), and industrial partner, Solar Earth Technologies Ltd. Potential applications include the incorporation of flexible solar cells into Solar Earth Technologies's next solar roadway product, portable power supplies for next generation mobile electronic devices, and solar charging vehicles. Solar cells will be fabricated with a plasma enhanced chemical vapor deposition (PECVD) cluster tool at Simon Fraser University using thin low-cost solar grade monocrystalline Si wafers. The technical challenges that must be overcomeinclude the development of a high-throughput substrate thinning technique, the implementation of an effective light trapping management strategy that aims to maximize light absorption with ~10 times less material, and the demonstration of high-flexibility and high-efficiency photovoltaic prototype devices. With the proposed project, Solar Earth Technologies Ltd. will acquire new technology to integrate into their next generation solar roadway product. In addition, a team of 9 students and researchers will gain hands-on industry-relevant skills relating to semiconductor device fabrication and optical and electrical characterization, while simultaneously receiving guidance and training from representatives of the industrial partner. Thedevelopment of the new solar cell technology may lead to new environmentally-friendly commercial products and new jobs in the renewable energy and high-tech sectors for Canadians. The goal of developing clean technologies and linking research performed in a laboratory with commercialization and consumer adaptation cycles, a priority for the Canadian government, will have been achieved through the successful completion of this project.
