Solar cell module and method of manufacturing the same

1. A solar cell module comprising:

first and second solar cells aligned in an arrangement direction; and

a wiring member configured to electrically connect the first and the second solar cells to each other, wherein

the first solar cell includes a photoelectric conversion part and a connection electrode formed on a first principal surface of the photoelectric conversion part,

the connection electrode directly and periodically contacting the wiring member via tops of convex shapes with a set periodicity at the surface of the connection electrode; wherein

the periodic contact surfaces are arranged in parallel rows that cross the arrangement direction at a bias angle,

and the wiring member is further mechanically bonded to the connection electrode surface by resin adhesive surrounding the contact surfaces.

2. The solar cell module of claim 1 , wherein the contact surfaces are circular and have diameters of between 3 microns to 20 microns.

3. The solar cell module according to claim 1 , wherein the connection electrode is formed along the arrangement direction on the first principal surface.

4. The solar cell module according to claim 2 , wherein, the wiring member has a conductive layer surface, and each concave shape forms a dent in the conductive layer.

5. The solar cell module according to claim 1 , wherein the bias angle is approximately 30 degrees.

6. The solar cell module according to claim 1 , wherein the bias angle is substantially orthogonal to the arrangement direction.

7. The solar cell module according to claim 1 , wherein the set periodicity is approximately 100 microns.

8. The solar cell module according to claim 1 , wherein the connection electrode surface is completely filled by concave shapes aligned in regular rows in two dimensions.
