Abstract
- The massive adoption of renewable energy especially photovoltaic (PVs) panels is expected to create a huge waste stream once they reach end‐of‐life (EoL). Despite having the highest embodied energy, present photovoltaic recycling neglects the high purity silicon found in the PV cell. Herein, a scalable and low energy process is developed to recover pristine silicon from EoL solar panel through a method which avoids energy‐intensive high temperature processes. The extracted silicon was upcycled to form lithium‐ion battery anodes with performances comparable to as‐purchased silicon. The anodes retained 87.5 % capacity after 200 cycles while maintaining high coulombic efficiency (>99 %) at 0.5 A g−1 charging rate. This simple and scalable process to upcycle EoL‐solar panels into high value silicon‐based anodes can narrow the gap towards a net‐zero waste economy. [ABSTRACT FROM AUTHOR]
