The present invention provides a method of manufacturing a solar cell, the method including: a process of forming a first semiconductor layer on an upper surface of a semiconductor wafer and forming a second semiconductor layer, having a polarity different from a polarity of the first semiconductor layer, on a lower surface of the semiconductor wafer; a process of forming a first transparent conductive layer on an upper surface of the first semiconductor layer to externally expose a portion of the first semiconductor layer and forming a second transparent conductive layer on a lower surface of the second semiconductor layer to externally expose a portion of the second semiconductor layer; and a plasma treatment process on at least one of the first transparent conductive layer and the second transparent conductive layer, wherein the plasma treatment process includes a process of removing the externally exposed portion of the first semiconductor layer and the externally exposed portion of the second semiconductor layer.
