Summary:A sintered crystalline silicon solar cell front side silver slurry after laser cutting comprises, by weight, 4-15% of acrylic resin solution, 0.5-3% of enclosed-type curing agent, 2% of dispersing agent, 70-90% of silver powder, 0.2-2% of thixotropic agent and 0. 5-5% of glass powder. The preparation method comprises the following steps of putting the acrylic resin solution and the enclosed-type curing agent in a blender according to a proportion to mix and stir, wherein a stirring speed is 50 revolutions/min; adding the dispersing agent after stirring for 20 min and then stirring for 30min; and then, adding the glass powder and the silver powder, stirring evenly to form a paste-like semi-fluid, placing in a heated water bath at 50DEG C- 70 DEG C and heating to 60DEG C, adding the thixotropic agent, and stirring at a slow speed for 4 hours so that a silver slurry finished product is formed, wherein the stirring speed is 50 revolutions/min. In the invention, a light receiving area can be greatly increased and
