6 FAQs about [What are the automatic dissolving agents for photovoltaic panels ]

Which reagent is used to separate different layers in PV modules?

In this study, low toxicity and environment-friendly reagent DMPU was used as the separating medium to separate different layers in PV modules. Compared with the traditional chemical swelling reagents, DMPU has higher boiling point which can provide a high temperature operating environment.

Which e-waste will be used if a photovoltaic module is scrapped?

The crystalline silicon-based module which contains many high-value elements (Si, Ag, Cu) and accounts for 65% of the production cost of photovoltaic modules will be the main E-waste when it was scrapped [ , , ].

Are PV panels used in experiment a defective product?

Actually, the PV panels used in experiment are defective products during the production process, but the structure of module is complete. These unqualified modules are stacked and some have been for several years. Those PV modules are ideal raw materials for research.

Can crystalline silicon PV modules be recycled?

As a large number of photovoltaic (PV) modules are approaching the end of their lifespan, the management of end-of-life crystalline silicon PV modules, especially the recycling of solar cells, is imminent.

How to separate a PV module from a solar cell?

The separated PV modules are filtered and sieved to obtain a mixture of glass and backsheet strips as well as a mixture of (solar cell + EVA) and backsheet. The glass and backsheet strips can be separated using hot air. Furthermore, an appropriate density reagent can be used to separate (solar cell + EVA) and backsheet.

What is a crystalline silicon PV module?

A standard crystalline silicon PV module consists of an aluminum frame, junction box, glass, solar cell, backsheet, and EVA (ethylene vinyl acetate) (Kang et al., 2012).
