NOVELTY - The method involves providing a substrate (10) including a doped layer (18). A patterned material layer (24) partially overlapping the doped layer is formed on the substrate. A first metal layer (26) is conformally formed on the patterned material layer and the doped layer. A patterned mask layer (28) totally overlapping the patterned material layer is formed on the first metal layer. A second metal layer is formed on the doped layer that is not overlapped by the patterned material layer. The patterned mask layer, the first metal layer and a part of the patterned material layer are removed.    USE - Method for fabricating a solar cell i.e. photovoltaic solar cell.    ADVANTAGE - The method enables forming the patterned mask layer through photolithography process and ohmic contact between a metal silicide layer and the doped layer in the solar cell so as to form patterns including smaller width, thus increasing a light absorbing area and enhancing power conversion efficiency. The method enables utilizing the material of the second metal layer to be copper so as to reduce manufacturing cost of the solar cell, while providing customized production of the solar cell. The method enables performing texture process on a surface of the substrate to reduce reflection of radiation, so that light absorbing capability of the surface can be improved. The method enables modifying a part of a mask corresponding to changed patterns and selecting existing masks to form required patterns when electrode structure patterns are modified or small scale production is performed, thus saving time needed for forming a new frame for the solar cell.    DETAILED DESCRIPTION - The substrate is a silicon wafer or die that is made of semiconductor material e.g. single crystalline silicon, poly crystalline silicon and amorphous silicon.
