Abstract: [Object] An object of the present invention is to provide a polyester film for solar cells, which has excellent heat resistance and hydrolysis resistance; and a highly durable solar cell which comprises a solar cell back sheet comprising the above-described polyester film. [Means for Solution] The present invention provides a polyester film for solar cells which has a terminal carboxyl group concentration of not higher than 0.013 eq/kg (13 eq/ton) and a microscopic endothermic peak temperature Tmeta (?C) determined by differential scanning calorimetry (DSC) of not higher than 220?C.

Abstract: PROBLEM TO BE SOLVED: To provide a white laminated polyester film excellent in smoothness. SOLUTION: The white laminated polyester film consists of at least a white polyester layer (A) and a polyester layer (B), and the white polyester layer (A) contains titanium dioxide with a mean particle size of 0.01-3 μm and the surface glossiness of the film calculated from the side of the white polyester layer (A) is 60% or more and the number of projections with a height of 200 μm or more on the surface of the white polyester layer (A) is 20 pieces/m2 or less.
