Project R-16801

Thermomechanical Effects and In-Situ Strain Monitoring in Perovskite Photovoltaic Devices (Research)

Perovskite solar cells combine high efficiency with low production costs, and their tunable bandgap makes them ideal candidates for tandem devices, promising even greater performance in PV modules. Despite progress in improving stability, outdoor degradation remains a major challenge, contrasting with their promising results under accelerated ageing conditions. Thermal and light cycling have been identified as key stressors, yet their interaction with encapsulation materials and the underlying mechanisms are not fully understood. This project will investigate these mechanisms through innovative in-situ and non-destructive characterization techniques, enabling accurate quantification of stressors and avoiding artifacts caused by destructive methods. Furthermore, it will develop predictive models that integrate physics-based approaches with AI, offering a novel framework for understanding and forecasting degradation. Finally, by correlating indoor and outdoor performance, the project will establish representative testing protocols and acceleration factors, paving the way for more reliable perovskite PV modules and accelerating their commercialization.
