The invention discloses a conductive paste for forming the electrode on the surface of solar cell, which contains conductive powder, mixed glass and organic phase; wherein, the mixed glass comprises the following two types of glass components: the first type of glass is at least one selected from the tellurium glass which does not contain lead substantially and having tellurium, bismuth, lithium as the essential component; The second type of glass is at least one kind of lead silicate glass, which having lead and silicon as essential components and does not contain tellurium substantially. The invention also provides a solar cell prepared by printing the conductive paste as a surface electrode and a manufacturing method of the solar cell. The solar cell made of the conductive paste of this invention has good EL performance in inspection, excellent ohmic contact of the cell, high cell conversion efficiency, better reliability, and strong bonding strength, the adhesion performance is taken into account while improving reliability and ohmic contact.
