Zusammenfassung:	The invention relates to an organic mask electronic paste of an SE solar battery. The electronic paste comprises the following materials by mass percent: 30-50 percent of synthesized resin, 0.5-10 percent of coloring agent, 1-10 percent of additive, 5-25 parts of thickening agent and the balance of an organic solvent, wherein the pH value of the organic mask electronic paste is equal to or smaller than 7; the synthesized resin comprises components A, B and C, accounting for 10-18 percent, 12-20 percent and 8-12 percent of the mass of the electronic paste respectively; the component A is one or a mixture selected from the following components: rosin and rosin derivatives with conjugated double bonds and carboxylic groups; the component B is phenolic resin with carboxylic groups; and the component C is one or a mixture selected from the following components: modified epoxy resin with carboxylic groups, modified polyester resin with carboxylic groups, and acrylic resin. The organic mask electronic paste of the SE solar battery disclosed by the invention has the properties of acid resistance, alkali dissolution and hydrophobicity. The invention further relates to a method for producing a selective emitter of the SE solar battery.
