This review paper presents an overview of studies of Potential Induced Degradation (PID) in copper indium gallium diselenide (CIGS) photovoltaics. It reviews the observations reported in literature, the proposed origins of this high voltage-difference-driven degradation effect and the applied testing methods. Studies on cell, mini-module and module level are presented and compared. Possible preventive measures against potential induced degradation in CIGS solar devices are also discussed.
