NOVELTY - An electroconductive composition contains silver powder, glass powder containing lead oxide, vehicle including resin and solvent, and dispersing agent which disperses and stabilizes silver powder and glass powder. The content of silver powder in the composition is 70-95 %mass. The content of glass powder with respect to 100 parts mass of silver powder is 1-10 parts mass. The glass powder contains lead oxide-boric oxide as main component, zinc oxide or titania as trace component, alumina and silica. The total content of alumina and silica in glass composition is 1-10 mol%.    USE - Electroconductive composition is used for manufacturing solar cell used for solar-cell module (all claimed).    ADVANTAGE - The electroconductive composition has excellent water resistance, adhesiveness and electroconductivity.    DETAILED DESCRIPTION - An electroconductive composition contains silver powder, glass powder containing lead oxide, vehicle including resin and solvent, and dispersing agent which disperses and stabilizes silver powder and glass powder. The content of silver powder in the composition is 70-95 %mass. The content of glass powder with respect to 100 parts mass of silver powder is 1-10 parts mass. The glass powder contains lead oxide-boric oxide as a main component, zinc oxide or titania as a trace component, alumina and silica. The total content of alumina and silica in the glass composition is 1-10 mol%. The electroconductive composition is used for forming n-type semiconductor layer (12) which penetrated the silicon-nitride layer (11) formed on p-type-semiconductor substrate (14), and is formed under the silicon-nitride layer (11), and electrode (13). INDEPENDENT CLAIMS are included for the following:    (1) manufacture of solar cell (1); and    (2) solar-cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows sectional view of solar cell.
