Zusammenfassung:A conductive paste composition, a preparation method and a use thereof, as well as a crystalline silicon solar cell are disclosed. The conductive paste composition contains a silver powder and an aluminum powder, and contains a lead-boron-selenium glass frit or a bismuth-boron-selenium glass frit. The conductive paste composition can perform effective etching of a passivation film of an n-type crystalline silicon solar cell during a high temperature firing, and also does not over-oxidize the aluminum powder contained therein, thereby forming an electrode having decent electrical contact with a p-type doped emitter.
