Project R-16076

A physics-based model for irreversible degradation prediction of PV modules. (Research)

PV modules are deployed in diverse climates, where environmental stress factors trigger multiple degradation processes that reduce performance and energy yield. Existing prediction models are either empirical, linking degradation to time or simple conditions, or physics-based, focusing on single mechanisms but often relying on fitted parameters rather than measurable properties. This Ph.D. project aims to develop physics-based models that link stress factors to specific electrical parameters of PV modules instead of overall power. Using measurable material properties or design factors will allow sensitivity analysis and design optimization. The models will be tested through laboratory and field experiments, validated with long-term datasets, and integrated into imo-imomec and TotalEnergies' PV performance frameworks for more accurate lifetime predictions.
