Abstract:
A biaxially stretched polyester film for protecting a back surface of a solar cell, containing a polyester resin that is polymerized with addition of a Ti catalyst, a Mg compound, a P compound and a nitrogen-containing heterocyclic compound, and having a volume resistivity at 285° C. is 10×107 Ω·cm or less, is improved in hydrolysis resistance and electrostatic adhesion property.
