Aging and durability

The specificity of the GUIDE team is to have been amongst the first teams to identify the importance of developing spatially resolved characterization to understand and remedy damage mechanisms.

In order to continue to enhance our know-how, we have also adapted to new needs, also related to the energy and environmental transition with the aging mechanisms of PV materials and systems and thermal and electrical insulation.

These "top-down" activities are generally carried out in strong interaction with industrialists.
 

• Microstructure (chemical structure, free volume, molecular mobility, crystallinity)
• Morphology at different scales
• Mechanical and electrical properties
• Development of experimental investigation tools
• Development of predictive models, in particular molecular modelling
