Solar cell module

A solar cell module, comprising:

• a plurality of solar cells two-dimensionally disposed on a light-receiving surface;
• a inter-connector which is disposed on front surfaces of the plurality of solar cells, electrically connects the plurality of solar cells, and has a light-diffusing shape on a surface on a light-entering side;
• a light-diffusing member disposed along a formation direction of the inter-connector to be adjacent to one solar cell among the plurality of solar cells in a direction parallel to the light-receiving surface;
• and
• a protective member which is disposed on the light-entering side of the plurality of solar cells, the light-diffusing member, and the inter-connector, and has a first principal surface and a second principal surface opposite the light-entering side of the first principal surface,
• wherein when an average distance of a distance between a front surface of the one solar cell and the second principal surface and a distance between the second principal surface and a front surface of the light-diffusing member adjacent to the one solar cell is expressed as D, a refractive index of the protective member is expressed as n, and a critical angle for total reflection satisfying sin R=1/n on the second principal surface is expressed as R,
• the inter-connector on the front surface of the one solar cell is disposed in a zone other than a zone between a position at a distance of 3.46×D from, among ends of the light-diffusing member, an end closest to the one solar cell in a direction of the one solar cell and a position at a distance of 2×D×tan R from, among the ends of the light-diffusing member, an end farthest from the one solar cell in the direction of the one solar cell.
