PROBLEM TO BE SOLVED: To provide a solar battery module excellent in environmental resistance and durability.SOLUTION: In a solar battery module containing a solar battery element, a sealing material, a light receiving face protection material and a back surface protection material, the light reception face protection material is joined to the light reception face of the solar battery element through the sealing material at the light reception face side of the solar battery or joined to the light reception face through no sealing material. The back surface protection material is joined to the back surface of the solar battery element through the sealing material at the back surface side of the solar battery. The sealing material at the back surface side contains ultraviolet light absorber and inorganic oxygen generating agent. The back surface protection material is an organic polymer sheet, and the inorganic oxygen generating agent is selected from peroxide of alkali metal, peroxide of alkali earth metal and a combination thereof.SELECTED DRAWING: Figure 2 |
