Abstract
The surface recombination velocity of a silicon sample is reduced by deposition of a thin hydrogenated amorphous silicon or hydrogenated amorphous silicon carbide film, followed by deposition of a thin hydrogenated silicon nitride film. The surface recombination velocity is further decreased by a subsequent anneal. Silicon solar cell structures using this new method for efficient reduction of the surface recombination velocity is claimed.
