To address the substantial volume of solar PV waste, researchers have conducted studies aimed at recovering various materials from EoL PV panels. This paper provides in-depth analysis of recovery methods for extracting silver from waste solar panels that are available in recent literature.
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...
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.
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.
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.
Despite these efforts, the recovery of silver (Ag), a crucial and valuable element in the PV modules, is often overlooked, due to its low concentration. Nonetheless, it is a fast depleting resource with limited natural ore deposits. The aim of this review is to present various methods developed for extracting Ag from EoL solar modules.
