<P>PROBLEM TO BE SOLVED: To provide a back sheet which exhibits excellent adhesion to a sealing resin layer, and adhesion of which sustains for a long time in a solar cell module. <P>SOLUTION: In a polyester resin back sheet for solar cell module, the dipole component γb out of the components of surface free energy of a surface in contact with the sealing resin layer of the back sheet is 3 [mN/m] or less, and the hydrogen bond component γc is 20 [mN/m] or less. The polyester resin back sheet is preferably subjected to ultraviolet ozone treatment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
