POLYESTER FILM AND METHOD FOR MANUFACTURING SAME, SOLAR CELL BACKSHEET AND SOLAR CELL MODULE

摘要

Provided is a polyester film having a high withstanding voltage progress rate which includes a polyester support (16) in which the end carboxylic acid value (AV) is 3 to 20 eq/ton and IV is 0.65 to 0.9 dl/g and a conductive layer (3) which is provided at least on one side of the polyester support (16), wherein the surface specific resistance RO of the conductive layer (3) is 106 to 1014 Omega/sq and an in-plane distribution of the surface specific resistance RO of the conductive layer (3) is 0.1 to 20%.
