A new recycling method utilizing high-pressure water-jet delamination has been developed to recover materials from end-of-life photovoltaic modules. This approach was evaluated within the Quasar Horizon Europe project and aims to enhance material recovery compared to traditional methods.
The process effectively separates layers of glass, encapsulant, solar cells, and backsheet, producing high-purity glass and mixed material fractions. Subsequent processing involves density-based separation techniques and eddy-current methods for metal recovery.
Analytical results indicate that silver purity reached 97%, while copper in the recovered smart wire was at 78%. The findings highlight the need for further refinement of the silicon fraction due to residual impurities, emphasizing the importance of selecting appropriate recycling processes for material end uses.
