NOVELTY - The solar cell module comprises a bearing substrate (100), a backsurface electrode layer (200) arranged on the bearing substrate, a light absorption layer (300) arranged on the backsurface electrode layer, a front electrode layer (600) arranged on the light absorption layer, and a connection wiring line (700) electrically connecting the front electrode layer to a metal nanowire. The width of the connection wiring line is different according to the position. The width of the connection wiring line increases from the backsurface electrode layer.    USE - Used as a solar cell module.    ADVANTAGE - The solar cell module exhibits good photovoltaic and conversion efficiency, and high reliability.    DETAILED DESCRIPTION - The solar cell module comprises a bearing substrate (100), a backsurface electrode layer (200) arranged on the bearing substrate, a light absorption layer (300) arranged on the backsurface electrode layer, a front electrode layer (600) arranged on the light absorption layer, and a connection wiring line (700) electrically connecting the front electrode layer to a metal nanowire. The width of the connection wiring line is different according to the position. The width of the connection wiring line increases from the backsurface electrode layer. An intermediate area is arranged between a lower region and an upper region of the wiring line. The metal nanowire has a diameter of 5-20 nm and a length of 0.1-100 mu m. The light absorption layer comprises a groove that passes through the light absorption layer and exposes a part of the backsurface electrode layer. The connection wiring line is extended to the downward from the front electrode layer, and is filled through the groove. The metal nano wire is distributed in the interface of the connection wiring line and exposed to backsurface electrode layer through the groove. An INDEPENDENT CLAIM is included for a method for manufacturing of a solar cell module.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic cross-sectional view of a solar cell module.
