PURPOSE:To prevent deterioration due to ultraviolet rays, in a solar battery module, by using resin film including ultraviolet-ray absorbing agent, as the material of the light receifing surface of the solar battery module. CONSTITUTION:A plurality of solar battery cells are emvedded and fixed in a space formed by outer surface members, which comprise an ultravioletray- absorbing-agent kneaded type polyester film 11, i.e., the material for a light recieving surface, and a back-surface protecting film 15 comprising the same material as the material for the light receiving surface or polyvinylflouride resin, with a bonding resin 21 such as EVA resin. In the ultraviolet-ray- absorbing-agent kneaded type polyester film, the ultraviolet-ray absorbing agent absorbs the ultraviolet rays. Thus the deterioration of the polyester itself due to the ultraviolet rays is prevented, and weather resistance is improved. As a result, the deterioration of the solar battery module due to the ultraviolet rays is prevented. |
