To reduce the demand for fossil fuel energy, one of the solutions is using an renewable energy sources, such as wind andsolar. Solar energy is increasingly becoming the hottest issue in recent years because of its merits in installation and operation. In2015, about 50.7 GW photovoltaic (PV) systems were installed around world. Many renewable energy organizations expect that thetotal PV system installation will be 60 GW in the coming year.[1] To sustain the long-term stability of the PV system, several instituteshave performed tests based on IEC standards, such as IEC 61215 for silicon crystalline PV modules and IEC 61646 for thin film PVmodules and IEC 61730-1&2 for safety tests. In the case of amorphous silicon thin film modules,[2,3] its performance can be loweredbecause its natural characteristics under sun light called, the Staebler-Wronski effect.[4,5] Therefore, some companies conduct lightsoaking tests to guarantee stable electric performance before shipment. On the other hand, in the case of having high degradationcharacteristics at the maximum power, this test could take much time for production and lead to an increase in product cost. To solvethis technical difficulty and obtain actual stable performance power of silicon-based amorphous solar modules, the current-inducedstabilization (CIS) technique was proposed and assessed.
