| 简介 |
Provided are : a solar cell sealing film, which contains resin particles in which an organic rare earth complex has been enclosed in an acrylic resin as wavelength conversion material and is able to maintain improvement of the power generation efficiency of solar cell elements over long periods; and a solar cell. The present invention is a solar cell sealing film containing an olefin (co)polymer-containing resin material and a wavelength conversion material, and a solar cell using same. The solar cell sealing film is characterized in that : the wavelength conversion material is resin particles obtained from an acrylic resin enclosing an organic rare earth complex; the acrylic resin is a polymer obtained by reacting an acrylic resin composition containing (meth)acrylate monomers, crosslinking agent, and an azo polymerization initiator; the crosslinking agent is a compound represented by formula (I) : [in the formula, R1 and R2 each independently represent a hydrogen atom or methyl group and n is an integer 2-14]; and the content of the crosslinking agent, when n is 2 in formula (I), is 0.1-5 parts by mass with respect to 100 parts by mass of the (meth)acrylate monomer and, when n is 3-14, is 0.1-50 parts by mass with respect to 100 parts by mass of the (meth)acrylate monomer. |
