Abstract: The present invention relates to a conductive paste for forming a conductive track or coating on a substrate, particularly suitable for use in solar cells. The paste comprises a solids portion dispersed in an organic medium, the solids portion comprising electrically conductive material and an inorganic particle mixture wherein the inorganic particle mixture comprises substantially crystalline particles. The present invention also relates to a method of preparing a conductive paste, a method for the manufacture of a surface electrode of a solar cell, an electrode for a solar cell and a solar cell.

Abstract: 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.

Abstract: The present invention relates to conductive pastes suitable for use in solar cells, to a method of manufacturing a light receiving surface electrode of a solar cell, and to a light receiving surface of a solar cell. The paste includes a mixed oxide (e.g. a glass frit) which includes lead, tellurium, bismuth and at least 0.5 wt % in total of WO3, MoO3, CeO2 and BaO.
