Abstract of the article: The shift towards a renewable energy economy necessitates robust technological support that prioritizes sustainability. Presently, the photovoltaic (PV) industry is characterized by linear economy models, energy-intensive production, downcycling, and limited environmental sustainability. An avenue towards sustainable technologies is through embracing circular economy principles, particularly circular design concepts. Within the design of crystalline PV modules, encapsulation poses a challenge. Specifically, the encapsulation process currently in use hinders high-value recycling or module remanufacturing, thus limiting the potential to extend product lifespans and close material loops. This study investigates new encapsulant materials suitable for the eco-design of PV modules, aiming to assess their physical and optical characteristics. The objective is to support a more effective future recycling scheme and enhance the circularity of the PV value chain. The existing encapsulation technique, which relies on ethylene vinyl acetate (EVA), presents performance limitations and demands an alternative solution. Emerging encapsulation technologies such as thermoplastics (TPO) and elastomers (POE) are explored and compared in terms of their performance, sustainability, and recyclability. The NEST project focuses on addressing end-of-life (EoL) module issues and advancing eco- design practices.
