摘要： A solar cell module includes a solar cell string in which solar cells each having a light-receiving surface without metal electrodes and a back surface with metal electrodes are electrically connected along a first direction. A back-surface protection member is disposed on a back side of the solar cell string. The solar cell string includes cell connecting members positioned between solar cells adjacent in the first direction. A lateral surface at a second direction end of the cell connecting member is situated in line with the lateral surface of the solar cell, wherein the second direction is orthogonal to the first direction. A principal surface of the back-surface protection member on the light-receiving side, a portion of the cell connecting member exposed to the light-receiving surface and a lateral surface at a second direction end of the cell connecting member are similar in color to the light-receiving surface.

摘要： An object of the present invention is to provide a manufacturing apparatus for a solar cell group that is likely to be recognized as having a good color balance when viewed by humans. The manufacturing apparatus for a solar cell group of the present invention includes an arrangement operation unit (12) that arranges solar cells and a machine learning unit (20). The solar cell group is formed by planarly arranging the solar cells. The solar cells have a light receiving surface and include an antireflection material on the light receiving surface side. Some of the solar cells have a variation in color element due to a difference in thickness of the antireflection material or a difference in refractive index of the antireflection material. The machine learning unit (20) performs machine learning using a correlation between an arrangement of the solar cells and a determination result by humans on color balance of the solar cell group as training data. When the solar cell group is manufactured, the machine learning unit (20) generates an arrangement model of the solar cells that is predicted to be determined to have a good color balance as the solar cell group by humans' visual recognition based on information on color elements of each solar cell, and then the arrangement operation unit (12) arranges each of the solar cells based on the arrangement model.

On a light-receiving side of the solar cell string, a light-transmissive light-receiving-surface protection member is disposed, and a back-surface protection member is disposed on a back side of the solar cell string. The one or more of wiring members comprises a braided wire composed of a plurality of metal element wires and having a flat-shaped cross-section. A first principal surface on the light-receiving side of the one or more of wiring members is connected to a one or more pairs of metal electrodes of the back contact solar cell. The one or more of wiring members has an electroconductive black layer on the entire first principal surface.

摘要： The solar cell includes: a first metal seed layer and a first plating layer provided on a first surface of a photoelectric conversion section; a second metal seed layer provided on a second surface of the photoelectric conversion section; and a third metal seed layer and a third plating layer provided on the lateral surface and the peripheral edge of the second surface of the photoelectric conversion section. The first metal seed layer is in electrical continuity with the third metal seed layer, while the second metal seed layer is in electrical non-continuity with the third metal seed layer. By supplying electricity to at least one of the first metal seed layer and the third metal seed layer, the first plating layer and the third plating layer are formed simultaneously.

摘要： A solar cell module comprises cell groups each containing solar cells, and each solar cell includes photoelectric converters, N number of which being connected in series, and first, second and third terminals. When the first terminal on one end of a first cell group has a reference potential, the second terminal on the other end of the mth cell group is connected to the first terminal on one end of another cell group, and N number of the third terminals of the mth cell group are respectively connected to N number of the first terminals of an m+1th cell group. The difference in potential between the second terminal on the other end of the mth cell group and the first terminal on one end of the other cell group is 10% or less of the difference in potential between the second and first terminals of the mth cell group.

摘要： A solar cell module, which is easily coordinated with the color of an exterior member at the installation position, comprises a solar cell; a light receiving side sealing material and a light receiving side protection member laminated and disposed in this order on a light receiving side with reference to the solar cell; and a back-side sealing material and a back-side protection member laminated and arranged in this order on a back side on the opposite side from the light receiving side. A value computed from a measured value of the color of reflected light combining positive reflected light and diffused reflected light which are based on light that has become incident on an object to be measured, and a measured value of the color only of the diffused reflected light based on the light that has become incident on the object to be measured, satisfies a specific condition.
