Disclosed is a method of manufacturing a solar cell, the method including forming a tunneling layer over one surface of a semiconductor substrate, forming a semiconductor layer over the tunneling layer, forming a conductive area including a first conductive area of a first conductive type and a second conductive area of a second conductive type in the semiconductor layer, and forming an electrode including a first electrode connected to the first conductive area and a second electrode connected to the second conductive area. The forming of the conductive area includes forming a mask layer over the semiconductor layer, forming a doping opening corresponding to at least one of the first conductive area and the second conductive area in the mask layer using a laser, and performing doping using the doping opening.
