Title:
LAMINATED SHEET AND METHOD FOR MANUFACTURING SAME, SOLAR CELL BACK SHEET, SOLAR CELL MODULE, AND METHOD FOR MANUFACTURING SOLAR CELL BACK SHEET
Document Type and Number:
WIPO Patent Application WO/2014/091973
Kind Code:
A1
Abstract:
A laminated sheet having: a layer having a polybutylene terephthalate resin as a principal component (P1 layer); and a layer having a polyolefin resin as a principal component (P3 layer). A solar cell back sheet, characterized in that the acetic acid permeability (Pa) (g/m2/day) at 85°C and water vapor permeability (Pw) (g/m2/day) at 40°C 90% RH satisfy relationships (1) 200 ≤ Pa and (2) Pw ≤ 2.5. Provided are a laminated sheet having a better moist heat resistance and an improved capacity to obtain both heat resistance and adhesion performance with respect to a sealing member compared with a conventional laminated sheet in which a polybutylene terephthalate resin is used, and a method for manufacturing the laminated sheet. Also provided are a solar cell module back sheet that is inexpensive and that is capable of preventing discoloration of the collector electrode of a solar cell while maintaining the power generation characteristics of the solar cell module over a long period, and a method for manufacturing the solar cell module back sheet.
