摘要： The present invention discloses a conductive silver aluminum paste, a preparation method, an electrode, and an N-type Topcon battery. The conductive silver aluminum paste comprises silver powder, metal powder containing aluminum element, powder containing silicon or boron element, glass powder, and organic carrier; wherein, when defining the total weight of the conductive silver aluminum paste as 100%, the weight percentage content of each component is: silver powder 80.0%-90.0%, metal powder containing aluminum element 0.5%-3.0%; powder containing silicon or boron element 0.1%-1.0%; glass powder 1.5%-6.0%; organic carrier 7.0%-15.0%. The present invention meets requirements for electrode materials of current development of N-type Topcon batteries well, and has advantages of low contact resistances, high open circuit voltages, high photoelectric conversion efficiency, and high output power.
