摘要： 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.

摘要： A solar cell module includes a solar cell, a wiring member electrically connected to the solar cell, a light-receiving-surface encapsulant and a back-surface encapsulant that cover the solar cell, a light-receiving-surface protecting member; and a back-surface protecting member. The back-surface protecting member does not contain a metal foil. A back-side metal electrode contacts the back-surface encapsulant. The arithmetic mean roughness of the surface of the back-side metal electrode that contacts the back-surface encapsulant is less than 0.1 μm. The back-surface encapsulant comprises a crosslinked olefin resin.

摘要： In the solar cell module, a first solar cell and a second solar cell are stacked together with an electroconductive member interposed therebetween, such that a cleaved surface-side periphery on a light-receiving surface of the first solar cell overlaps a periphery on a back surface of the second solar cell. The first solar cell and the second solar cell each have: photoelectric conversion section including a crystalline silicon substrate; collecting electrode; and back electrode. At a section where the first solar cell and the second solar cell are stacked, the collecting electrode of the first solar cell and the back electrode of the second solar cell are electrically connected to each other by coming into contact with the electroconductive member. An insulating member is provided on a part of the cleaved surface-side periphery on the light-receiving surface of the first solar cell, where the collecting electrode is not provided.
