  • Publication number: 20220328714
    Abstract: 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.
