To test that assumption, they used partially fabricated solar cells that had been fired at 750 C or at 950 C and — in each category — one that had been exposed to light and one that had been kept in the dark. They chemically removed the top and bottom layers from each cell, leaving only the bare silicon wafer.
All amorphous silicon-based solar cells exhibit such degradation with light, which is called the Staebler–Wronski effect (Staebler and Wronski 1977a, 1977b).The effect anneals out nearly completely within a few minutes at temperatures of about 160 ∘ C, and anneals substantially in outdoor deployment at summer operating temperatures of 60 ∘ C.
