New silicon photovoltaic technologies have been developed in recent years, such as PERC (Passivated Emitterx000D
Rear Contact) cells. New failure mechanisms have appeared for these technologies, such as Light and Elevatedx000D
Temperature Induced Degradation (LeTID) and passivation layer degradation. New characterization approachesx000D
are therefore required to assess these loss mechanisms during the manufacturing process and in the field. Thisx000D
project will assess impedance spectroscopy as a non-destructive technique to characterize degradationx000D
mechanisms and performance losses in the silicon PERC cells and modules manufactured by Canadian Solarx000D
Inc. Impedance spectroscopy (IS) uses an AC signal with varying frequency to measure the impedance of anx000D
electrical system and determine an equivalent circuit. Changes in the equivalent circuit can be associated withx000D
performance losses and cell degradation. A non destructive technique for identifying specific degradationx000D
mechanisms would complement existing techniques and would be used by Canadian Solar Inc. to furtherx000D
improve its manufacturing processes and the quality of the products it can deliver to its customers. This couldx000D
translate to an increased global market share and expanded employment base in Canada. Importantly,x000D
photovoltaics are an environmentally friendly renewable energy source that can help meet Canada's energyx000D
demands.
