摘要： The solar cell includes a plurality of light-receiving-side finger electrodes on a light-receiving surface of a photoelectric conversion section having a semiconductor junction. The light-receiving surface of the photoelectric conversion section is covered with a first insulating layer. Each light-receiving-side finger electrodes include: a first metal seed layer provided between the photoelectric conversion section and the first insulating layer; and a first plating metal layer being conduction with the first metal seed layer through openings formed in the first insulating layer. The solar cell includes an isolated plating metal layer pieces contacting neither the light-receiving-side finger electrodes nor the back-side finger electrodes. On the surface of the first insulating layer, an isolated plating metal crowded region is present in a form of a band-shape extending parallel to an extending direction of the light-receiving-side finger electrodes.

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.

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.
