“…5) To improve the reliability and durability of PV modules, major overhaul of the related International Electrotechnical Commission (IEC) standards has been underway, mainly under IEC Technical Committee 82 (IEC TC82), 6,7) in liaison with international collaborative frameworks, such as the International PV Quality Assurance Task Force and dedicated workshops. [8][9][10] Among the IEC standards for testing of module durability, damp heat (DH) testing in the dark is widely employed. However, in the field, heating of the module is accompanied by sunlight irradiation, as shown in Fig.…”

To ensure a longer lifetime for photovoltaic (PV) modules, many accelerated test standards are being developed or revised. Among the test standards, damp heat (DH) testing in the dark is widely employed to test the module durability. However, in the field, high temperature is usually accompanied by light irradiation. This difference can result in a degradation not observed in the field, especially in the case of Cu(In,Ga)(S,Se) (CIGS) PV modules. To explore suitable test procedures that simulate performance in the field appropriately, we investigated the effects of light irradiation and forward biasing, during DH testing and potential induced degradation (PID) testing of CIGS PV modules. In the case of the CIGS product we have tested, both light irradiation and forward biasing have suppressed degradation in DH as well as PID tests, and no degradation was found after light soaking. These results suggest the needs to add corresponding option(s) to the relevant test standards.
