The lifetime-limiting failure mechanisms of CuInGaSSe (CIGSS) solar devices made by Shell Solar Industries (SSI) were investigated. In our study, SSI minimodules were exposed to dry-heat 85??C, damp-heat 85??C/85% RH and aerobic and anaerobic room temperature and 85??C water baths. After 200 hours exposure to moisture-containing environments, the average device performance decreased by more than 30%...
This paper briefly reviews our work on the syntheses and applications of a family of fluorene-based polymers. We have found that fluorene as a monomer offers a number of advantages, the most significant being its ability to impart solubility while maintaining a high degree of delocalization. An improved Pd-catalyzed polymerization procedure has enabled the preparation of a large variety of fluorene...
