6 FAQs about [Demand for conductive silver paste from photovoltaic panel waste]

Can silver be recycled from crystalline silicon photovoltaic (PV)?

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...

Will halving the amount of silver needed to make solar cells affect demand?

Halving the amount of silver needed to make solar cells, combined with fewer, more efficient modules, will affect global demand for the commodity. Image: Armin Kübelbeck, Wikimedia Commons

What is the recycling process for silicon-based PV panels?

In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).

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 extract silver from photovoltaic panels?

Pyrolysis and gravimetric separation methods are the most effective, which recovered 91.42 %and 94.25 % silver from crystalline panels and 96.10% silver from CIS PV panels. Yang et al. (2017) used methane sulphonic acid (MSA) with an oxidation agent (hydrogen peroxide) to extract silver from photovoltaic panels.

What is the economic value of crystalline silicon PV panels?

The economic value of the valuable metals is $13.62/m 2, resulting in a profit of $1.19 per recycling of 1 m 2 of crystalline silicon PV panels. The breakdown of total revenue generated after selling the recovered valuable materials is as follows: 46% (aluminium), 25% (silver), 15% (glass), 11% (silicon), and 3% (copper).
