摘要： A solar cell and a solar cell module including the solar cells are disclosed. The solar cell includes a substrate of a first conductive type; an emitter layer of a second conductive type positioned at a light receiving surface of the substrate; a plurality of first electrodes that are positioned on the emitter layer and are electrically connected to the emitter layer; and at least one first current collector that is positioned on the emitter layer in a direction crossing the plurality of first electrodes, wherein a thickness of each of the plurality of first electrodes is different from a thickness of the at least one first current collector, and a difference of the thickness of the each first electrode to the thickness of the at least one current collector is equal to or less than about 0.5 times the thickness of the at least one first current collector.
