Abstract: A method for manufacturing a solar cell includes forming a conductive type region on one surface of a semiconductor substrate, and forming an electrode on the conductive type region, wherein the forming of the electrode includes forming a metal layer on an entire area of the conductive type region, forming a printed electrode layer having a pattern on the electrode layer, and forming an electrode layer between the conductive type region and the printed electrode layer, wherein the forming of the electrode layer includes patterning the metal layer by using the printed electrode layer as a mask.

Abstract: A solar cell is discussed, which includes a tunneling layer on one surface of a semiconductor substrate; a first conductive type region on the tunneling layer; a second conductive type region on the tunneling layer; a first electrode and a second electrode, the first electrode connected to the first conductive type region and the second electrode connected to the second conductive type region. The tunneling layer includes a first portion and a second portion. The first portion is disposed to correspond to at least a part of the first and second conductive type regions and has a first thickness. At least a part of the second portion is disposed to correspond to a boundary portion between the first conductive type region and the second conductive type region. The second portion has a second thickness greater than the first thickness.
