    Abstract: A method of manufacturing a solar cell according to an embodiment includes the steps of: forming an emitter layer by ion-implanting a first conductive type dopant to a first surface of a semiconductor substrate; and forming a back surface field layer by ion-implanting a second conductive type dopant to a second surface of the semiconductor substrate. When an additional dopant is a dopant other than the first and second conductive type dopants, an amount of the additional dopant doped during the forming the back surface field layer is larger than an amount of the additional dopant doped during the forming the emitter layer.
