Abstract
This solar cell module includes a solar cell and a wiring member. The solar cell includes a collecting electrode on a light-receiving side of a photoelectric conversion section, and a back electrode on a back side of the photoelectric conversion section. Sequentially from the photoelectric conversion section side, the collecting electrode includes a first collecting electrode and a second collecting electrode, and the back electrode comprises a first back electrode and a second back electrode. It is preferable that the surface roughness Ra1 of the first collecting electrode and the surface roughness Ra2 of the second collecting electrode satisfy Ra1≥Ra2 and Ra2=1.0 to 10.0 μm. It is also preferable that the outermost layer of the second collecting electrode and the outermost layer of the second back electrode are mainly composed of the same electroconductive material.
