Abstract
An electrode paste for a solar cell, a solar cell electrode using the paste, a solar cell having such an electrode, and a fabrication method of the solar cell are described. The paste for a solar cell electrode comprises a first component that includes silver (Ag) or a metal alloy containing the silver (Ag); a second component that includes zinc (Zn), and at least one selected from a group consisting of silicon (Si), aluminum (Al), copper (Cu), manganese (Mn), bismuth (Bi), phosphorous (P), boron (B), barium (Ba), and palladium (Pd); a leaded or lead-free glass frit; and a resin binder that is dispersed in an organic medium.
