A conductive silver aluminum paste includes the following components by weight percentage: 80.0%-90.0% of silver powder; 0.3%-2.5% of aluminum powder; 0.0%-1.5% of silicon powder; 1.0%-6.0% of first-type glass powder; 0.5%-4.0% of second-type glass powder; and 7.0%-15.0% of organic vehicle. The first-type glass powder is Pb-Zn-B-O-M glass powder, and the second-type glass powders is Ba-B-O-M glass powder, M is at least one of alkali metal elements; the organic vehicle is a vehicle of organic resin and/or cellulose, and a content of the organic resin and/or the cellulose in the organic vehicle is not higher than 10.0% of a total mass of the organic vehicle. By introducing two different types of glass powder, the contact resistance between the metal grid and the PN junction layer is reduced, thereby obtaining high-performance silver aluminum pastes for N-type Topcon monocrystalline silicon cells and high-efficiency electrode metallization for N-type silicon solar cells.
