6 FAQs about [Photovoltaic panel grinding and peeling method]

Can selective grinding remove resin from glass in silicon-based PV panels?

Selective grinding during the initial stage of grinding is effective for removing resin from glass in silicon-based PV panels. Many previous studies on the separation of glass from resin have investigated the applicability of chemical processes, but we achieved separation by brief physical processes.

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.

What are the physical processes of PV panels?

Physical processes involve mechanical treatments applied to the PV panel, such as shredding and milling (B. Sorensen., 2017) (Granata et al., 2014) (M. Ito, 2016) (Azeumo et al., 2019; Xuefeng et al., 2021).

How to remove resin from glass in silicon-based PV panel recycling?

As mentioned above, the most extensively studied methods for the removal of resin from glass in silicon-based PV panel recycling involve heating or chemical additives , , . However, we developed a mechanical separation technology to rapidly effect the separation with low environmental load and low energy consumption.

Why do PV panels need mechanical crushing?

As the powder created by mechanical crushing is simple to transport, it can substantially reduce transportation expenses. (2) The surface of most PV panels has been damaged by long-term use.
