This research demonstrates an innovative recycling method for extracting critical materials from end-of-life solar panels, suggesting major environmental benefits.
Key Points
The aim is to develop a more sustainable recycling process for cadmium telluride solar panels to recover critical materials efficiently.
Developed an electrochemical recycling strategy to extract cadmium and tellurium from end-of-life solar panels.
Eliminated the need for externally sourced hydrogen peroxide by generating it in situ during the process.
Conducted techno-economic and life cycle analyses to assess the viability and environmental impact.
Achieved near-quantitative extraction efficiencies of approximately 99% for cadmium and tellurium.
Reduced total energy consumption by over 65% compared to conventional recycling methods.
Identified key economic and environmental hotspots for further improvements in the recycling process.
