<p><P>PROBLEM TO BE SOLVED: To provide a sheet for sealing the rear surface of a solar battery having the excellent weather resistance (hydrolysis-resistant property), with good lamination strength not only in the environment to be utilized actually for a solar battery module but also in accelerating evaluation under high temperature and high humidity at the time of evaluating a solar battery module, capable of not only preventing poor appearance derived from delamination but also maintaining electric output characteristics as a solar cell. <P>SOLUTION: A sheet for sealing the rear surface of a solar battery B comprises a laminated member with at least one layer of a fluorine-based resin film base material adhered with a polyurethane-based adhesive b. The sheet is provided with an acryl-based resin coat layer (c) made from an acryl-based resin having at least one kind of functional groups from a hydroxyl group, an amide group, and an amino group on both sides of the fluorine-based resin film base material to be contacted with the polyurethane-based adhesive. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
