Solar cell and method for fabricating the same

摘要

In a method for fabricating a solar cell, an amorphous silicon film of a first conductivity type is formed on a substrate, and nickel silicide is formed thereon. The amorphous silicon film is crystallized through heat treatment to obtain a crystalline silicon film of the first conductivity type. Residual nickel silicide on the surface of the crystalline silicon film of the first conductivity type is removed. Another crystalline silicon film of a second conductivity type is further formed on the surface of the crystalline silicon film of the first conductivity type.
