PV DiKlaWi - PV Diagnosis, Classifacation, and Recycling

The inspection of PV systems with infrared cameras for hot spot detection is state of the art, However, it is influenced by environmental parameters, which can lead to misinterpretations. the Electroluminescence is an innovative and much more meaningful method, which it through Energization allows defects (cracks, fractures, delaminations) to be found down to the cell level detect. A system is developed that is based on the electroluminescence measurement in Combination with domain-informed AI algorithms reliably monitor the state of modules diagnosed. This diagnostic method is developed in the laboratory and based on real PV systems evaluated. Only defective PV modules should be recycled in the circular economy supplied, degraded are to a second phase of use in the context of social projects be made accessible.
