Encapsulant delamination behavior in PV glass recycling

Researchers in Spain investigated effective separation of encapsulants from PV glass with a focus on melting behavior and resistance to the hot knife-method of delamination. The results indicated that thermoplastic polyolefin encapsulants were the easiest to remove from the PV glass.Spanish researchers from the Public University of Navarra (UPNA) and the National Renewable Energy Centre (CENER) have investigated the melting points of three conventional encapsulant materials in an end-of-life PV panel recycling research project. They also determined the ease of removing them using a hot-knife delamination ...
