Abstract: A solar cell module includes a plurality of solar cells each comprising a substrate, an emitter region placed at the substrate, an anti-reflection region placed on the emitter region, first electrodes placed on the substrate, first bus bars placed on the substrate and connected to the first electrodes, second electrodes placed on the substrate, and second bus bars placed on the substrate and connected to the second electrodes. The anti-reflection region includes a first opening region through which part of the emitter region is exposed and one or more second opening regions through which part of the emitter region is exposed. The first electrode is connected to the exposed emitter region of the first opening region through the anti-reflection region by metal plating and the first bus bar is connected to the exposed emitter region of one or more second opening regions through the anti-reflection region by metal plating. An interconnector electrically connects the first bus bar and the first bus bar or the second bus bar of an adjacent solar cell of the plurality of solar cells.
