FLUORINE-CONTAINING RESIN FILM AND SOLAR CELL MODULE

摘要

Disclosed is a fluorine-containing resin film which is formed from a fluorine-containing resin composition and has a thickness of 10 to 50 wherein the fluorine-containing resin composition is prepared by adding 10 to 30 parts by mass of titanium oxide or a composite-oxide-type inorganic pigment to 100 parts by mass of a resin component comprising 60 to 95 parts by mass of a vinylidene fluoride resin and 5 to 40 parts by mass of a methacrylic acid ester resin, and wherein the peak intensity ratio of a II-type crystal, which is expressed by (A)/((A)+(B))×100 wherein A represents the peak height at 840 cm−1 and B represents the peak height at 765 cm−1 in a measurement chart produced by an infrared absorption spectrum, is 60% or more and the total crystallinity is 30% or more as calculated from an X-ray diffraction profile.

1. A fluorine-containing resin film of thickness 10 to 50 μm, formed from a fluorine-containing resin composition obtained by adding 10 to 30 parts by mass of a titanium oxide or composite oxide-containing inorganic pigment with respect to 100 parts by mass in total of resin components consisting of 60 to 95 parts by mass of a vinylidene fluoride-based resin and 5 to 40 parts by mass of a methacrylic acid ester-based resin, the fluorine-containing resin film having a H-type crystal peak intensity ratio, represented by (A)/((A)+(B))×100 where (A) is the peak height at 840 cm−1 and (B) is the peak height at 765 cm−1 in a measuring chart using an infrared absorption spectrum, of at least 60%; and an overall degree of crystallinity of at least 30% as calculated from an X-ray diffraction profile.
