6 FAQs about [High-pressure grinding of photovoltaic panels]

How is high-voltage pulse crushing used in photovoltaic panel treatment?

High-voltage pulse crushing technology was applied to photovoltaic panel treatment.Crushed products were separated by sieving and dense medium separation. Glass was in the 45–850 μm fraction and purified by dense medium separation. Ag was highly condensed (3000 mg/kg) in the sieved products.

Can a high-voltage pulse method enrich PV panel waste?

After separation, there was a 30% increment in silver concentration. Moreover, the processing cost of this method is found to be around 0.0019 $/W, making it an economical solution for recycling PV panels. Zhao et al. (2020) performed a parametric investigation on a high-voltage pulse method to enrich PV panel waste.

How to separate a photovoltaic panel?

In this study, we crushed a photovoltaic panel by high-voltage pulse crushing and then separated the products bysieving and dense medium separation with the aim of selective separation and recovery of various materials in the panel.

How a high pulse PV panel is used?

In the high pulse method, the PV panel was cut into six sample pieces, then inserted into 2 L of a reactor filled with water after crushing the silicon PV panel, used high voltage pulse method to recover valuable metals such as silver, tin, copper, silicon, and aluminium.

How to improve the sustainability of silicon PV panels?

Recommendations include the use of computer-based simulation models, enhanced lab-scale experiments, and industry-scale implementation to ensure the sustainable recycling of silicon PV panels. Sajan Preet: Writing – review & editing, Writing – original draft, Formal analysis, Data curation, Conceptualization.

What are the disintegration mechanisms in high-voltage pulse crushing?

We considered that there are two main disintegration mechanisms in high-voltage pulse crushing, namely,electrical disintegration (ED) and electrohydraulic disintegration (EHD). In the ED mechanism, breakdown occurs in the solid materials through the application of a high voltage, resulting in selective crushing of the materials’ boundaries.
