Research on Photovoltaic Panel Glass Separation Technology

How effective are physical separation methods for PV panels?

The implementation of physical separation methods for PV panels proved to be effective for both LC-GHG and LC-RCP. Fig. 4 shows the mass balance flow at the end-of-life of a PV panel.

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.

Can electrostatic separation be used for recycling photovoltaic panels?

Z.S. Zhang, B. Sun, J. Yang, Y.S. Wei, S.J. He Electrostatic separation for recycling silver, silicon and polyethylene terephthalate from waste photovoltaic cells The design of an optimal system for recycling photovoltaic panels is a pressing issue.

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.

Can Egda be used to separate glass-Eva in photovoltaic modules?

Non-toxic reagent EGDA was used to separate the glass-EVA in photovoltaic modules for the first time. The glass in 20 mm × 20 mm photovoltaic pieces can be separated adequately in 3 h. EGDA can be recycled by filtration to be reused. Solar cells can keep their initial size due to the moderate swelling ability of EGDA.

How to separate glass from PV glass?

To effectively separate glass from the PV piece, the penetration of separation reagents into the glass-EVA gap is extremely important. Therefore, the wettability of the medium on glass is an important factor. The PV glass used in this experiment has one side with a rough surface and the other side with a smooth surface.
