Examining Light-Induced Degradation with Combined-Accelerated Stress Testing Open
While further understanding is sought, the results suggest that a module can show no degradation in performance through a qualification test light soak, (IEC 61215: 2021 MQT 19.1 requirement of 10 kW minimum on one side). Yet, such cells m…
