Abstract:
1. A method for producing a solar cell electrode, comprising the steps of: applying on at least part of a light-receiving surface of a semiconductor substrate a conductive paste comprising conductive component, glass frit, and resin binder, the conductive component being selected from the group consisting of: (i) silver particles and metal particles selected from the group consisting of Pd, Ir, Pt, Ru, Ti, and Co, (ii) alloy particles comprising silver and metal selected from the group consisting of Pd, Ir, Pt, Ru, Ti, and Co, and (iii) silver particles and core-shell particles in which a metal selected from the group consisting of Pd, Ir, Pt, Ru, Ti, and Co is coated on a surface of silver or copper, wherein content of the metal particles is 0.01 to 10 wt %, based on the total amount of the conductive paste; and firing the conductive paste.
