Abstract :
The data collected from single-junction p-i-n a-Si:H alloy solar cells during a 2309 day flight of the LIPS III satellite were analyzed. While there are problems associated with the interpretation of the data, the data are useful for characterizing the effect of the space environment on a-Si:H solar cells. Marked decreases in the cell parameters were observed. Evidence is presented to show that photodegradation is the primary cell degradation mechanism
