Abstract
Disclosed is a method for manufacturing a solar cell, the method including: forming a semiconductor layer on one surface of a semiconductor substrate; forming a mask layer including a first layer and a second layer sequentially on the semiconductor layer; texturing another surface of the semiconductor substrate using the mask layer as a mask; forming a patterned mask layer by forming an opening at the mask layer through a laser patterning using a laser; and forming a conductive region through a doping process of doping a portion of the semiconductor layer exposed through the opening with a dopant.
