Extracting valuable metals from waste materials is a fundamental aspect of recycling, especially in sustainability and resource conservation. Among these metals, silver extraction from photovoltaic panels is pivotal in the panel recovery process.
This research introduces a novel process aimed at the recovery of silver and silicon from end-of-life photovoltaic panels. The leaching efficiency and kinetics of ground cake powder in sulfuric acid, ferric sulfate, and thiourea were investigated in the leaching system.
Chemical leaching is the most efficient and economically feasible method for metal recovery in mineral processing, which has been applied in Li-metal batteries' recycling, and thus can be used for recovering silver from solar cells after receiving the separated solar cells from the mechanical and thermal delamination processes.
However, most valuable metals in the solar cell, especially silver (1% in c-Si solar cells, which is much larger than 0.0005% in natural silver ore), are theoretically recyclable (Figure 1b). Thus, silver recovery should be operated and added to the solar panel recycling.
Nevertheless, silver can be 100% retrieved from the chemical extract, with a purity of 68–96% w/w (average 86% w/w), in crystal (face center cube) structure, containing minor metal impurities. Many photovoltaic panels (PVs), have accumulated as a waste and even more PVs are nearing their End-of-Life (EoL).
The authors declare no conflict of interest. Abstract Silver can be recycled from the end-of-life crystalline silicon photovoltaic (PV), yet the recycling and its technology scale-up are still at an early stage especially in continuously oper...
