【 摘 要 】

This report describes continuing studies on photoluminescence (PL), electroluminescence (EL), Raman, and nuclear magnetic resonance (NMR) by the University of North Carolina-Chapel Hill during the three years and the extension period. Systematic studies on the transition materials and their solar cells and a review of the photo-induced structural changes in correlation to the electronic degradation have led to better understanding of the factors determining the photodegradation in a-Si:H solar cells. NHR established significant differences, as in the bonding of hydrogen in the hot-wire- and plasma-deposited amorphous silicon.
