METHOD FOR MANUFACTURING A SOLAR CELL |
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.
