NOVELTY - A silver conductor paste comprises silver powder, glass powder, organic carrier and additive. The glass powder is lead-boron-silicon-zinc-titanium-aluminum-oxide (Pb-B-Si-Zn-Ti-Al-O) series glass powder. The organic carrier includes organic solvent, thickening agent, surfactant and diluting agent. The thickening agent is ethylcellulose, acrylic ester and/or dinitrocellulose. The surfactant is stearate. The diluting agent is ethyl alcohol, acetate or terpene. The additive includes barium oxide (BaO) and calcium oxide (CaO) powders.    USE - A silver conductor paste for solar cell electrode.    ADVANTAGE - The paste greatly improves electrical property of electrode, and increases photoelectric conversion efficiency of the cell; thus ensuring excellent ohmic contact between paste and substrate.    DETAILED DESCRIPTION - Silver conductor paste comprises silver powder, glass powder, organic carrier and additive. The silver powder is present at 65-85 wt.%, and includes two types of silver powders, where first silver powder has particle size of 3-15 (preferably 5-10) mu m, and second silver powder is 0.1-3 (preferably 1-5) mu m. The silver powder of first particle size is present at 20-50 wt.%. The glass powder is Pb-B-Si-Zn-Ti-Al-O series glass powder present at 1-10 wt.%; and includes 50-70% lead oxide (PbO), 2-5% (B2O3), 20-30% silicon oxide (SiO), 1-5% zinc oxide (ZnO), 0.1-3% titanium oxide (TiO) and 2-5% aluminum oxide (Al2O3). The organic carrier is present at 10-20 wt.%; and includes (wt.%) organic solvent (60-80), thickening agent (5-20), surfactant (1-10) and diluting agent (0.1-5). The solvent is terpineol, tributyl citrate, turpentine wood oil or carbitol. The thickening agent is ethylcellulose, acrylic ester and/or dinitrocellulose. The surfactant is stearate. The diluting agent is ethyl alcohol, acetate or terpene. The additive is present at 0.1-3 wt.%; and includes barium oxide (BaO) and calcium oxide (CaO) powders with mass ratio at 0.5-1.5 and particle size at 1-5 mu m. An INDEPENDENT CLAIM is included for a method of preparing silver conductor paste by mixing silver powder with glass powder and additive; mixing with organic carrier, and stirring in water bath at 50-70 degrees C; and grinding prepared solid powder with organic carrier.
