PROBLEM TO BE SOLVED: To provide a technique for enhancing the power generation efficiency by scattering light in a solar battery module.SOLUTION: A solar battery cell 10 can receive incident light at both surfaces thereof, and a front-surface-side electrode 30 and a back-surface-side 32 are arranged on both the surfaces thereof. A first protection member 12 is disposed on one surface side of the solar cell 10. A first sealing member 14 is disposed between the first protection member 12 and the solar cell 10. A second protection member 16 is disposed on the other surface side of the solar cell 10. A second sealing member 18 is disposed between the second protection member 16 and the solar cell 10. The transmittance satisfies: the first protection member 12, the first sealing member 14>the first protection member 12, the first sealing member 14, the second sealing member 18>the first protection member 12, the first sealing member 14, the second sealing member 18, the second protective member 16. Further, the transmittance of the first sealing member 14 is higher than the transmittance of the second sealing member 18.SELECTED DRAWING: Figure 3 |
