Title:
太陽電池裏面封止用ポリエステルフィルム及びその製造方法、並びに太陽電池裏面保護膜及び太陽電池モジュール
Document Type and Number:
Japanese Patent JP5306274
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyester film for sealing-up a reverse face of a solar cell that has both hydrolysis resistance and high voltage resistance.SOLUTION: The polyester film for sealing-up the reverse face of the solar cell is a polyester film which is 250 to 600 μm thick and biaxially orientated, and includes a first resin layer and a second resin layer containing polyester and a catalyst-originating titanium compound respectively, wherein the first resin layer is fused and laminated on at least one surface of the second resin layer, and a rising-temperature crystallization peak Tc (°C), a crystallization calorific value ΔH (j/g), an intrinsic viscosity IV (dl/g), a terminal carboxyl group concentration AV (equivalent amount/ton), a plane orientation degree ΔP, and a glass transition temperature Tg of each of the layers measured at a temperature-rising rate of 5°C/minute by a differential scanning calorimeter (DSC) satisfy specific relations.
