The long-term stability of solar cells is a crucial factor for the competitiveness of a technology. In this study, the accelerated aging of CIGS solar cells was studied, and the influence of an applied bias during the endurance test on the open-circuit voltage Voc and fill factor (FF) was investigated. Time constants for parameter drifts of the open-circuit voltage and the associated activation energy...
