Shingled and Bifacial Photovoltaic Module Designs for High Performance

在目前的硅太阳能组件设计中，当高性能的单个电池被组装成组件时，性能会下降——这种性能下降是由于功率输出和组件中受潮和热应力等环境因素导致的性能下降。随着市场对高功率和长寿命模块的需求不断增加，我们建议开发功率超过400w且对环境因素敏感度低的高功率模块，以实现40年的预期性能寿命。这将通过关注用于互连的多层封装材料和先进纳米结构材料来实现，这些材料将通过最先进的表征方法、数值模拟和仿真支持的性能测试来选择和验证。我们的主要模块技术将是瓦片和双面模块，多层聚合物材料将被考虑用于封装和无母线互连技术，以及用于细胞-细胞互连的导电粘合剂，以降低加工温度和由此产生的残余应力。所开发技术的成功商业化将有助于将平准化电力成本（LCOE）降低到实现温室气体排放目标所需的水平。这项工作的结果将为下一代光伏（PV）模块的制造提供加拿大制造的解决方案，这将使我们的团队成为可再生能源领域的世界领导者，同时为这一关键行业培养一批新的hqp。

In current silicon solar module designs, when high performance individual cells are assembled into modules, performance degrades---this performance reduction is in both power output and degradation due to environmental factors such as moisture ingress and thermal stress in the modules. With increasing demand in the market for high power and long-life modules, we propose to develop high power modules with power exceeding 400 W and low sensitivity to environmental factors to achieve a predicted performance lifetime of 40 years. This will be achieved by focusing on multi-layer encapsulatiion materials and advanced nanostructured materials for interconnects, selected and validated by state of the art characterization methods, numerical modelling and performance testing supported by simulations. Our primary module technology will be shingled and bifacial modules, and multi-layer polymer materials will be considered for the encapsulation and busbarless interconnect technology, as well as conductive adhesives used in cell-cell inter-connects to reduce processing temperatures and resultant residual stress. Successful commercialization of the technology developed will help towards lowering the levelized cost of electricty (LCOE) to levels required for achieving green house gas emission targets. The results of this work will enable a made-in-Canada solution for manufacturing of the next generation photovoltaic (PV) modules that will position our team as a world leader in renewable energy , while training a new cohort of HQPs for this critical industry.
