To provide a back sheet for solar battery modules which is arranged so that the deterioration of the material accompanying the hydrolysis can be prevented not only in an environment of actual use in a solar battery module, but also in an acceleration test in a high-temperature and high-humidity atmosphere to be factored in when making an assessment on the solar battery module, and poor appearance attributed to delamination can be prevented, and which is excellent in weather resistance, especially in hydrolysis resistance, insulation resistance and moisture-barrier property, and which allows an electricity output property to be maintained in the solar battery even after a weathering test, and to provide a solar battery module and a solar battery, each having the back sheet for solar battery modules.
A back sheet for solar battery modules comprises a laminate arranged by gluing together at least two base materials 1 with an acrylic adhesive agent 2. The acrylic adhesive agent includes acrylic polymer produced by polymerization of monomer components including a monomer expressed by the general formula (I): CH2=C(R1)-CO-OZ (I), where R1 is a hydrogen atom or a methyl group, and Z represents a hydrocarbon group having 4-25 carbon atoms.
