| Summary |
A step-stress accelerated degradation testing (SSADT) method was employed for the first time to evaluate the performance reliability of CIGS solar cells and device component materials in four encapsulated Al-framed test structures, using edge sealant and backsheet/moisture barrier film for moisture ingress control. The SSADT exposure used a 15oC and then a 15%RH increment step, beginning from 40oC/40%RH (40/40) to 85oC/70%RH (85/70) for a total DH exposure of 4204 h as of the moment. The SSADT study is currently ongoing and is to be finished at a final 85/85 DH exposure. A more comprehensive summary will be reported in the near future after the experiment is completed and the voluminous data are thoroughly processed and analyzed; the results may also allow a determination of whether T- and RH-dependent activation energy can be derived for use on the Peck equation |
