To identifying light and elevated temperature induced degradation, different procedures to perform accelerated testing were discussed. Typically, modules are aged in heated climatic chambers, and after a defined interval, characterized using a flash based bright currentvoltage (IV) characteristic. E.g. the change in MPP-Power can be used as a criteria, if the test can be aborted or more cycles are needed. In this poster, dark-IV-characteristics are evaluated as a alternative in-situ measurement tool.
