Abstract
A conductive paste for forming solar cell electrodes that obtains favorable electrical characteristics and sufficient adhesion strength to a substrate. The conductive paste for forming a solar cell electrode includes the following: a tellurium-based glass frit containing 30-70 mol % of tellurium, 15-40 mol % of tungsten, 5-30 mol % of zinc, 0-20 mol % of boron, and 0-10 mol % of zirconium (where a total content of boron and zirconium is greater than 0 mol %) in terms of oxides; a conductive powder having silver as a main component and specific surface area of 0.4 m/g or more; and an organic vehicle.
