    • PROBLEM TO BE SOLVED: To provide a solar cell module capable of ensuring connection reliability between a surface electrode and a tab line, regardless of presence of surface irregularities or materials of the surface electrode, wherein, in the solar cell module, a plurality of solar cells are connected in series and a surface electrode of at least one solar cell is connected to the tab line. SOLUTION: In the solar cell module, the plurality of solar cells are connected in series and a surface electrode of at least one solar cell is connected to the tab line. The surface electrode of the solar cell is connected to the tab line by thermo-compression bonding through a conductive adhesive layer where conductive particles distribute in binder resin composition. The conductive particles of ≥50 mass% have a major axis of 1-50 μm, a thickness of ≤5 μm, and an aspect ratio (= major axis/thickness) of 3-150. In addition, the particles are flake metal particles having hardness higher than the one of the surface electrode and the tab line. COPYRIGHT: (C)2011,JPO&INPIT
