Study raises questions on what causes silicon solar cell degradation

(PhysOrg.com) — After several hours of exposure to sunlight, silicon solar cells experience light-induced degradation, which can decrease their efficiency by up to 10%. In a new study, scientists have attempted to detect the oxygen dimer (O2i) in the predicted charge state that is widely considered to play a key role in this light-induced degradation. However, their search has been unsuccessful, casting doubt on the accepted degradation mechanism of silicon solar cells.
