Abstract
A fluororesin film on which no bubble streaks are formed even when it contains a sufficient amount of titanium oxide, in which deterioration of the fluororesin is suppressed, and which has a low transmittance of ultraviolet light at a wavelength of at most 360 nm and has excellent weather resistance and heat resistance, a method of its use, a backsheet for a solar cell module, and a solar cell module. The fluororesin film may be used for an outermost layer of a backsheet of a solar cell module. The fluororesin film contains an ethylene/tetrafluoroethylene copolymer as the main component, and also contains specific titanium oxide composite particles. An arithmetic mean roughness Ra of the film surface to be in contact with the air is at most 3 μm. Further, a backsheet comprising a laminate having a fluororesin film, and a solar cell module comprising the backsheet.
