The Public University of Navarre, a Spain-based higher education institution, and Spain’s National Renewable Energy Centre, a Madrid-based renewable research body, have developed a thermomechanical method to assess photovoltaic module recyclability by examining delamination forces across different encapsulants. Tests were conducted on ethylene vinyl acetate, polyolefin elastomer, and thermoplastic polyolefin, and Differential Scanning Calorimetry was applied to determine melting ranges for each encapsulant under controlled conditions. Results indicated that delamination forces decreased significantly once encapsulants exceeded their melting thresholds, with thermoplastic polyolefin requiring the lowest removal force. Ethylene vinyl acetate consistently showed higher adhesion and gel content than polyolefin elastomer, which displayed weaker polarity, slower crosslinking, and less standardized curing. Thermoplastic polyolefin, being non-crosslinked, melted directly and enabled easier removal, although it became viscous above 100 °C. Hot-knife separation recovered intact glass and viable cells, which researchers said was safer and more efficient than chemical or pyrolysis processes.
