Provided are: a sealing film for solar cells, which contains, as a wavelength conversion material, resin particles obtained by having an acrylic resin internally contain an organic rare earth complex, and which is capable of maintaining an effect of improving the power generation efficiency of a solar cell element for a long period of time; and a solar cell. A sealing film for solar cells, which contains a resin material containing an olefin (co)polymer and a wavelength conversion material, and which is characterized in that: the wavelength conversion material is configured from resin particles that are formed of an acrylic resin internally containing an organic rare earth complex; the acrylic resin is a polymer that is obtained by reacting a composition for acrylic resins, which contains, as a monomer, a hydrophobic monomer having a higher n-octanol/water partition coefficient than methyl methacrylate, and which additionally contains a crosslinking agent and an azo polymerization initiator. A solar cell which uses this sealing film for solar cells. |
