ABSTRACT:
A solar cell comprises a substrate; an n-type barium silicide layer being arranged on the substrate and containing Ba atoms and Si atoms; an n+-type barium silicide layer being arranged on the n-type barium silicide layer and containing impurity atoms which are at least one of atoms belonging to Groups 13 to 15 of the periodic table, Ba atoms, and Si atoms; an upper electrode arranged on the n+-type barium silicide layer; and a lower electrode arranged on the substrate.
