The present invention relates to a conductive paste useful for the manufacture of silicon solar cells and silicon solar cell modules, particularly for the backside of silicon wafers. The conductive paste includes metal particles, glass frit, an organic vehicle, and an adhesion promoter. The adhesion promoter includes a metal or metal oxide, or any other metal compound that converts to a metal or metal oxide at the firing temperature. The adhesion promoter includes at least one metal selected from the group consisting of tellurium, tungsten, molybdenum, vanadium, nickel, antimony, magnesium, zirconium, silver, cobalt, cerium, and zinc, or oxides thereof.
