Shingled and Bifacial Photovoltaic Module Designs for High Performance

在当前的硅太阳能模块设计中，当高性能的单个电池组装成模块时，性能降低-这种性能降低是由于环境因素（例如模块中的湿气进入和热应力）导致的功率输出和性能降低。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400 W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。这将通过专注于用于互连的多层复合材料和先进的纳米结构材料来实现，这些材料通过最先进的表征方法、数值建模和模拟支持的性能测试来选择和验证。我们的主要模块技术将是叠瓦和双面模块，多层聚合物材料将被考虑用于封装和无母线互连技术，以及用于电池互连的导电粘合剂，以降低加工温度和由此产生的残余应力。该技术的成功商业化将有助于降低电力（LCOE）的平准化成本，达到实现绿色房屋气体排放目标所需的水平。这项工作的结果将使加拿大制造的解决方案用于制造下一代光伏（PV）模块，这将使我们的团队成为可再生能源的世界领导者，同时为这个关键行业培训一批新的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.
