<p>The purpose of the present invention is to provide a filler sheet for solar cell modules, which has excellent durability, heat resistance and adhesion to a solar cell element, and which enables the production of a solar cell module with high efficiency by any one of a vacuum laminating method and a roll-to-roll method. The present invention is a filler sheet for solar cell modules, in which: both surfaces of an intermediate layer are provided with an adhesive layer; the intermediate layer is formed of a low-density polyethylene resin having a melting point of 90-130°C and a melt mass flow rate of 0.5-20 g/10 minutes, or a linear low-density polyethylene resin having a melting point of 90-130°C and a melt mass flow rate of 0.5-20 g/10 minutes; the adhesive layer is formed of at least one thermoplastic resin that is selected from the group consisting of acid-modified polyolefins, silane-modified polyolefins, ionomers and ethylene-(meth)acrylic acid copolymers; and the thickness ratio of the adhesive layer to the intermediate layer (adhesive layer/intermediate layer) is from 20/80 to 70/30.</p> |
