Rear Contact) cells. New failure mechanisms have appeared for these technologies, such as Light and Elevated_x000D_
Temperature Induced Degradation (LeTID) and passivation layer degradation. New characterization approaches_x000D_
are therefore required to assess these loss mechanisms during the manufacturing process and in the field. This_x000D_
project will assess impedance spectroscopy as a non-destructive technique to characterize degradation_x000D_
mechanisms and performance losses in the silicon PERC cells and modules manufactured by Canadian Solar_x000D_
Inc. Impedance spectroscopy (IS) uses an AC signal with varying frequency to measure the impedance of an_x000D_
electrical system and determine an equivalent circuit. Changes in the equivalent circuit can be associated with_x000D_
performance losses and cell degradation. A non destructive technique for identifying specific degradation_x000D_
mechanisms would complement existing techniques and would be used by Canadian Solar Inc. to further_x000D_
improve its manufacturing processes and the quality of the products it can deliver to its customers. This could_x000D_
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 energy_x000D_
demands., program purpose french : New silicon photovoltaic technologies have been developed in recent years, such as PERC (Passivated Emitter_x000D_
