Abstract:
1. A solar cell module comprising: a first solar cell arranged in an arranging direction having a first connecting electrode formed on a surface thereof in a direction perpendicular to the arranging direction; a second solar cell arranged in an arranging direction having a second connecting electrode formed on a back surface thereof in a direction perpendicular to the arranging direction; a wiring member electrically connected to the first connecting electrode and the second connecting electrode a bonding layer for bonding the wiring member on the surface of the first solar cell; wherein the wiring member extends to an arranged direction of the first solar cell and the second solar cell that is perpendicular to the direction of the connecting electrodes, wherein the wiring member has a protruding portion on the surface of the first solar cell and extending away from the second solar cell and beyond the bonding layer at an end of the wiring member and wherein an end of the protruding portion has burrs or deformations and is located inside a peripheral edge of the first solar cell and is located closer to the peripheral edge of the first solar cell away from the second solar cell than the bonding layer is to the peripheral edge of the first solar cell away from the second solar cell and further, the end of the protruding portion is located closer to the peripheral edge of the first solar cell away from the second solar cell than to the peripheral edge of the first solar cell closer to the second solar cell, wherein the burrs or deformations extend perpendicular to the first solar cell surface less than a combined thickness of the adjacent connecting electrode and its bonding layer.
