NOVELTY - A silicon-base solar positive silver slurry preparing method involves mixing silicon dioxide, lead oxide, boron oxide, titanium dioxide and aluminum oxide. The obtained mixture is hot melted, cooled, crushed, ball milled, dried and sieved to produce a glass powder. Vinyl cellulous resin is completely dissolved in a solvent, and filtered to obtain an organic carrier. The glass powder, sheet-like silver powder, nanometer silver powder, organic carrier, solvent and auxiliary agent are uniformly mixed in an agitator. The resulting mixture is dispersed in a three-roller machine, and filtered.    USE - Method for preparing silicon-base solar positive silver slurry (claimed) that is utilized in a battery.    ADVANTAGE - The method enables improving the leveling property and printing property of the silver slurry, increasing height of the grid line electrode, decreasing contact resistance of the battery and improving conversion efficiency of the battery by changing the adding proportions of the glass powder, sheet-like silver and nanometer silver powder.    DETAILED DESCRIPTION - A silicon-base solar positive silver slurry preparing method involves mixing silicon dioxide (5-30 weight%), lead oxide (30-75 weight%), boron oxide (5-30 weight%), titanium dioxide (2-15 weight%) and aluminum oxide (0.5-10 weight%). The obtained mixture is hot melted, cooled, crushed, ball milled, dried and sieved to produce a glass powder with average particle diameter of 0.4-1.2 mu m, where the total amount of the silicon dioxide, lead oxide, boron oxide, titanium dioxide and aluminum oxide is 100%. Vinyl cellulous resin (10-30 weight%) is completely dissolved in a solvent (70-90 weight%) in a constant-temperature water tank. The obtained product is filtered by 250-325 meshes screen to obtain an organic carrier, where the total amount of the vinyl cellulous resin and the solvent is 100%. The glass powder (0.5-5 weight%), sheet-like silver powder (40-85 weight%), nanometer silver powder (5-45 weight%), organic carrier (5-10 weight%), solvent (2-6 weight%) and auxiliary agent (0.2-2 weight%) are uniformly mixed in an agitator. The resulting mixture is dispersed in a three-roller machine and filtered by 325-400 meshes screen to obtain a slurry, where the total amount of the glass powder, sheet-like silver powder, nanometer silver powder, organic carrier, solvent and auxiliary agent is 100%.
