摘要： The present invention provides a method for manufacturing a solar cell. The method for manufacturing a solar cell comprises: forming via holes in a silicon wafer; forming a shallow emitter on the front surface and the rear surface of the wafer, connecting the inner walls of the via holes and the via holes; and selectively forming an emitter through the heavy doping of a dopant to provide a plurality of regions along a direction linking the via holes of the shallow emitter with a certain concentration or higher. Accordingly, the present invention can selectively form an emitter on an MWT solar cell by performing laser doping or etching on a region contacting a front surface electrode having a certain width and height.

摘要： A solar cell and a manufacturing method thereof. A method of manufacturing a solar cell includes: forming an emitter layer on a first surface of a semiconductor substrate; forming an insulation layer on the emitter layer; applying a chemical compound including a dopant having a conductive type of the emitter layer on the insulation layer according to a pattern; forming a high concentration emitter portion by removing a portion of the insulation layer corresponding to a positioning of the chemical compound and diffusing the dopant toward the emitting layer; removing the chemical compound; and forming a first electrode electrically connected to the high concentration emitter portion.
