The present invention relates to conductive pastes, suitable for use in solar cells, a method for the manufacture of a light receiving surface electrode of a solar cell, a light receiving electrode for a solar cell and a solar cell. The paste comprises a solids portion dispersed in an organic medium, the solids portion comprising electrically conductive metal, and mixed oxide, wherein the mixed oxide is a tellurium-bismuth-cerium mixed oxide and is substantially lead-free and substantially silicon-free.
