<P>PROBLEM TO BE SOLVED: To provide a light-reflecting film for solar power generation, which can maintain high regular reflectance for a long period of time while maintaining handling property as a film mirror, even when the film as a light-reflecting film for solar power generation is used for a long period of time in a severe environment, which is lightweight and flexible, which can be mass-produced in a large area while suppressing the cost of production, and which is excellent in light resistance and weather resistance and has a good regular reflectance with respect to solar heat, and to provide a reflecting device for solar power generation using the light-reflecting film. <P>SOLUTION: The light-reflecting film for solar power generation has a surface layer containing a copolymer comprising polysiloxane, polycaprolactone and a polydimethylsiloxane copolymer as structural elements, at least one layer of a resin substrate and a metal reflecting layer, in an outermost surface where solar light enters. <P>COPYRIGHT: (C)2012,JPO&INPIT |
