摘要： A method of manufacturing a solar cell includes: forming a dopant layer by doping a dopant to a semiconductor substrate; and forming an electrode electrically connected to the dopant layer. The forming of the electrode includes forming a metal layer on the dopant layer; and heat-treating the metal layer to form a first layer and a second layer. In the heat-treating of the metal layer, a portion of the metal layer adjacent to the semiconductor substrate forms the first layer including a compound formed by a reaction of the metal layer and the semiconductor substrate, and a remaining portion of the metal layer forms the second layer that covers the first layer.
