Abstract

A solar cell module includes a first solar cell, a second solar cell disposed with a gap from the first solar cell, and a light reflection sheet bridging between the first solar cell and the second solar cell across the gap. The light reflection sheet is at least partially bent between the first and second solar cells.

Claims

1. A solar cell module comprising:

a first solar cell;

a second solar cell disposed with a gap from the first solar cell; and

a light reflection sheet bridging between the first solar cell and the second solar cell across the gap, wherein

a portion of the light reflection sheet corresponding to the gap is at least partially bent.

2. The solar cell module according to claim 1, wherein

both surfaces of the bent portion of the light reflection sheet are curved surfaces, as seen in a cross-section of the light reflection sheet, having a minimum point as a lowest point at least in a part of the curve.

3. The solar cell module according to claim 2, wherein

the bent portion of the light reflection sheet protrudes toward the gap.

4. The solar cell module according to claim 3, wherein

the surfaces of the light reflection sheet includes a first surface to which the light reflection sheet faces to the first and second solar cells and a second surface opposite to the first surface,

in the bent portion, the first surface of the light reflection sheet enters into the gap beyond an extension of a first principle surface of the first solar cell to which the light reflection sheet is attached.

5. The solar cell module according to claim 4, wherein

in the bent portion, the second surface of the light reflection sheet also enters into the gap beyond the extension of the first principle surface of the first solar cell.

6. The solar cell module according to claim 2, wherein

the bent portion of the light reflection sheet has a curved shape.

7. The solar cell module according to claim 2, wherein

the portion of the light reflection sheet corresponding to the gap is entirely curved.

8. The solar cell module according to claim 1, wherein

the light reflection sheet comprises light reflection members connected to one another.

9. The solar cell module according to claim 1, wherein

the light reflection sheet includes a resin base member and a light reflection film on one surface of the resin base member, and

the light reflection sheet is bonded to the first solar cell such that the other surface of the resin base member of the light reflection sheet is attached to the first solar cell with an adhesive.

10. The solar cell module according to claim 9, wherein

a thickness of the adhesive in a portion lateral to an end of the first solar cell is larger than that in the other portion of the adhesive.

11. The solar cell module according to claim 10, wherein

a thickness of the adhesive at a corner of the end of the first solar cell is smaller than that in the other portion of the adhesive.
