Shingled and Bifacial Photovoltaic Module Designs for High Performance

点击翻译按钮获取中文摘要

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.
