Disclosed is a film for a backside sealing sheet of a solar cell, which is obtained by providing at least one surface of a base film with a resin layer that contains a conductive material, a coloring pigment and a resin that is obtained by copolymerizing an acrylic polyol resin with an ultraviolet absorbent and/or a light stabilizer. The conductive material is contained in an amount of 5-20% by mass relative to the total mass of the resin layer, and the resin layer has a surface resistivity of from 1.0 × 10 9 Ω/□ to 1.0 × 10 15 Ω/□.nConsequently, the film for a backside sealing sheet of a solar cell has excellent light resistance and excellent partial discharge voltage that serves as an index for electrical insulation. |
