NOVELTY - A solar cell, comprises an emitter region positioned on the substrate and containing a second impurity of a second conductivity type different from the first conductivity type, the emitter region being made of a non-crystalline semiconductor; and a surface field region positioned on the substrate and containing a third impurity of the first conductivity type, the surface field region being made of the non-crystalline semiconductor.    USE - The solar cell is used for generating electric energy from solar energy.    DETAILED DESCRIPTION - A solar cell, comprises a substrate (110) containing a first impurity of a first conductivity type and made of a crystalline semiconductor; an emitter region positioned on the substrate and containing a second impurity of a second conductivity type different from the first conductivity type, the emitter region being made of a non-crystalline semiconductor; a surface field region positioned on the substrate and containing a third impurity of the first conductivity type, the surface field region being made of the non-crystalline semiconductor; a first electrode connected to the emitter region; and a second electrode connected to the surface field region. At least one of the emitter region and the surface field region is made of amorphous metal silicide containing a metal material. An INDEPENDENT CLAIM is a method for manufacturing a solar cell, by forming an amorphous silicon layer containing an impurity on a silicon substrate; forming a metal layer containing a metal material on the amorphous silicon layer; performing a thermal process on the metal layer and the amorphous silicon layer and changing at least one portion of the amorphous silicon layer into amorphous metal silicide, to form an amorphous metal silicide region; removing a remaining portion of the metal layer; and forming an electrode connected to the amorphous metal silicide region.
