Abstract: A solar cell module comprises an upper glass plate, a front adhesive layer, a solar cell array, a back adhesive layer and a back plate superposed in sequence. The solar cell array comprises a plurality of cells, adjacent cells connected by a metal wire. At least one metal wire extends reciprocally between a surface of a first cell and a surface of a second cell adjacent to the first cell to form at least two conductive wires. The cells comprise secondary grid lines disposed on front surfaces thereof. The conductive wires are being welded with the secondary grid lines. At least one of the front adhesive layer and the back adhesive layer has a thickness of larger than or equal to the metal wire in a direction perpendicular to the cell, and smaller than 400 μm.
