AI Customer ServiceExtracting 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.
From an economic and productivity perspective in the recovery of silver from solar cells, the chemical leaching presents a viable technique. At present, the predominant method for leaching is the utilization of nitric acid, succeeded by precipitation with either NaCl or NaOH or by electrochemical refining.
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.
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.
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...
The significance of recovering silver from spent silicon solar cells cannot be overstated, particularly in light of the increasing demand for silver and the strict environmental regulations in place (Gervais et al., 2023). Moreover, the retrieval of raw materials is crucial for multiple reasons.
