The application discloses a conductive silver paste for photovoltaic cells and a preparation method thereof. The conductive silver paste comprises the following raw materials in percentage: 65-85% of silver powder and 1-3% of modified binder, and the rest is an organic carrier. In the printing process of the conductive silver paste, the substances in the organic carrier contact the silver powder, so that the silver chelate in the organic carrier is fully contacted, and then a stable conductive path can be formed during baking. The modified binder is a lead-free glass formed by taking bismuth trioxide as a main raw material to form a bismuth-based glass. The addition of calcium fluoride in the raw material can reduce the water absorption of the bismuth-based glass, thereby ensuring the stability of the resistivity. The addition of titanium dioxide can exist in a quadruple coordination form, so that the Si-O-Si bond in the glass is changed into a Si-O-Ti bond, thereby forming an interconnected tetrahedral structure, increasing the network connectivity of the glass, and simultaneously increasing the antireflection effect of the glass and the utilization rate of light energy.
