Fig. 7 shows the I–V curves for a module
employing an Iodine Oxygen encapsulant before and after the potential-induced degradation test by
applying 1000 V at 85 °C for 2 weeks.Even after the potential-induced degradation test for
2 weeks,no degradation was observed in the module involving the
Iodine Oxygen encapsulant (Fig. 7).
