Composite material with enhanced recyclability as encapsulant for photovoltaic modules

Encapsulation of photovoltaic cells was carried out using a transparent glass fiber reinforced composite with enhanced chemical recyclability based on matrix an epoxy resin containing cleavable functional groups. The current-voltage curves showed decrease 6.3% the short-circuit current (Isc) after encapsulation cell, lower than one observed for reference non-recyclable standard composite. Its performance stability under thermal cycling, ultraviolet (UV), and damp-heat exposure evaluated compared epoxy. Both resins good UV cycling accelerated aging. Moreover, power loss below 5% allowed by recyclable 1000 h exposure, even pronounced 4.7% in remains concern. Regarding recyclability, dissolved acetic acid dissolution fabrics were successfully recovered. A new module manufactured these fabrics, showing this time 12% Isc comparing non-encapsulated cell. Further work will consider improving moisture barrier properties composite, adjusting recycling conditions to allow component recovery valid modules.
