<p><P>PROBLEM TO BE SOLVED: To provide an adhesive sheet for a solar battery, from which an ethylene-based copolymer rarely overflows at the time of solar battery module fabrication and which can be suitably used in the solar battery module fabrication. <P>SOLUTION: The adhesive sheet for a solar battery is an adhesive sheet for the solar battery, which is manufactured by use of a T die connected to an extruding machine and which is constituted by integrally laminating three or more sheet layers containing an ethylene-based copolymer and an organic peroxide. At least one sheet layer out of the sheet layers is a low melt flow rate layer in which the melt flow rate of the ethylene-based copolymer is equal to or less than 20 g/10 minutes. The remaining sheet layer other than the low melt flow rate layer is a high melt flow rate layer in which the melt flow rate (MFR) of the ethylene-based copolymer exceeds 20 g/10 minutes. The total thickness of the low melt flow rate layer is equal to or more than 50% of the thickness of the adhesive sheet for the solar battery. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
