Claim Text:
1. A solar cell module, comprising: a plurality of solar cells each comprising a substrate having a first conductive type, an emitter region having a second conductive type which is opposite to the first conductive type and on the substrate, an anti-reflection region on the emitter region, a plurality of first electrodes in a first direction and electrically connected to the emitter region through a plurality of first opening regions in the anti-reflection region, a first bus bar crossing the plurality of first electrodes in a second direction and electrically connected to the emitter region through a plurality of second opening regions in the anti-reflection region, a plurality of second electrodes electrically connected to the substrate, and a second bus bar electrically connected to the plurality of second electrodes; a conductive metal interconnector to electrically connect the first bus bar and the second bus bar of an adjacent solar cell of the plurality of solar cells; and a conductive adhesion film between the first bus bar and the second bus bar and the interconnector, and contains a plurality of conductive particles dispersed in resin to electrically connect the first bus bar and the second bus bar and the interconnector, wherein the anti-reflection region comprises the plurality of first opening regions through which parts of the emitter region are exposed, the plurality of second opening regions through which parts of the emitter region are exposed, and a plurality of grooves which are spaced apart from the second opening regions and expose a portion of the insulator or the emitter region, wherein the plurality of first electrodes are formed through the first opening regions by metal plating, and wherein the first bus bar is in the plurality of grooves.
