Researchers in Austria have analyzed the crack propensity of backsheets made of polypropylene (PP) and have concluded these may be potentially used in solar module manufacturing, unlike co-extruded polyamide backsheets, which caused many headaches to the PV industry in the past. Furthermore, PP backsheets are claimed to have lower stiffness and higher flexibility than their laminated counterparts.A group of researchers led by the Polymer Competence Center Leoben in Austria has investigated the cracking propensity of co-extruded backsheets based on three layers of polypropylene (PP) in an effort ...Den vollständigen Artikel lesen ...
