LAMINATED POLYESTER FILM AS PROTECTIVE MATERIAL FOR REAR SURFACE OF SOLAR CELL |
摘要 |
The present invention provides a polyester film for a protective material for protecting a back surface of photovoltaic cell which exhibits a good hydrolysis resistance and an excellent adhesion property to a sealing resin for photovoltaic cells. The present invention relates to a polyester film for a protective material for protecting a back surface of photovoltaic cells which is in the form of a laminated polyester film comprising the below-mentioned polyester (A) layer as at least one of outermost layers of the film and at least one below-mentioned polyester (B) layer, the laminated polyester film having a terminal carboxyl group content of not more than 26 equivalents/t, and the polyester (A) layer being provided on at least one surface thereof with a coating layer formed of a polyurethane having at least one of a polycarbonate skeleton and a polyether skeleton, and a crosslinking agent:
·Polyester (A) layer: Layer formed of a polyester comprising an aromatic polyester as a main constitutional component and having a white pigment content of less than 8% by weight; and
·Polyester (B) layer: Layer formed of a polyester comprising an aromatic polyester as a main constitutional component and having a white pigment content of not less than 8% by weight. |
