摘要： A solar cell is disclosed. The solar cell includes a substrate containing first impurities of a first conductive type, an emitter layer containing second impurities of a second conductive type opposite the first conductive type, a first electrode electrically connected to the emitter layer, and a second electrode electrically connected to the substrate. The emitter layer and the substrate form a p-n junction. A doping concentration of the second impurities of the emitter layer linearly or nonlinearly changes depending on a depth of a position within the emitter layer.
