Extracting metals from photovoltaic panels after crushing

This study proposed a clean, high-efficiency, and low-cost technique for recovering Si from c-Si PV panels by combining mechanical crushing with electrostatic separation. After mechanical crushing, 82.8 wt% of Si will be crushed into powder and this part of Si is recovered by electrostatic separation.

Dias et al. (2018), after mechanical milling for crushing the silicon PV panels, used an electrostatic separator to segregate metal fractions of solar panels. This method predominantly recovered 100 % grade glass by recycling solar PV panels.

This paper proposes a comprehensive process for recycling of discarded silicon-based PV panels economically, environmentally, and efficiently. Based on the thermal properties of ethylene vinyl acetate (EVA), they are removed from the discarded PV panels at 600 °C with heating rate of 5 °C/min and maintain for one hour.

Recovering valuable metals such as Si, Ag, Cu, and Al has become a pressing issue as end-of-life photovoltaic modules need to be recycled in the near future to meet legislative requirements in most countries. Of major interest is the recovery and recycling of high-purity silicon (>99.9%) for the production of wafers and semiconductors.

In this study we investigated different physical route recovery methods such as crushing recycling, high voltage pulse, laser irradiance, and hot knife processes, targeting the retrieval of valuable materials like silicon, metals, glass, and encapsulants.
