A fabrication method of a selective emitter solar cell, including: forming a selective emitter solar cell base having a buried grid electrode; forming an anti-reflection layer on the emitter surface of the solar cell base; forming a bus-bar on the anti-reflection layer; and connecting the buried grid electrode with the bus-bar in the traversing direction underneath through the anti-reflection layer. Accordingly, the invention provides a selective emitter solar cell. With the method of the invention, emitters and bus-bars are made separately, the width of the emitters can be reduced according to actual needs, the area that is unnecessarily taken may be reduced, the effective area for a solar cell panel to receive sunlight may be increased. The invention improves conversion efficiency of a selective emitter solar cell panel from 16.5% to 18% or more.
