Single-crystal silicon point-contact solar cells show a degradation in their efficiency after being exposed to concentrated sunlight. This change has been linked to an increase in the surface recombination velocity. A similar effect is produced by carrier injection under forward bias. The annealing kinetics, the role of ultraviolet light, and possible causes for the creation of surface states are discussed.
