About Principle of Photovoltaic Panel Back Sheet Separation
The use of EGDA as a green layer separation reagent can achieve the effective separation of the glass from PV modules. The results of the FTIR spectrum ( Fig. 10 a) and GC–MS chromatogram ( Fig. 10 b) of the EGDA reagent before and after separation show that no new components are formed in the solution.

6 FAQs about [Principle of Photovoltaic Panel Back Sheet Separation]
Can electrostatic separation be used in silicon-based photovoltaic modules?
The objective of this study is to evaluate the use of electrostatic separation technique to segregate some of the main materials present in silicon-based photovoltaic modules: silver, copper, silicon, glass, and polymers from the back sheet and encapsulating material.
What are back-sheet materials for photovoltaic modules?
Back-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.
How to determine the degree of separation of PV panels?
In order to evaluate the degree of separation of PV panels, the separation rate of PV panels was introduced in this paper and it was determined by Eq. (1): (1) Separation rate ( %) = ( 1 − M b M a) × 100 where Mb is the mass of unseparated PV panels and Ma is the total mass of the PV panels placed in the reactor.
Why is it important to separate different layers of PV panels?
It is very important to realize the rapid and efficient separation between the different layers of the PV panels. After the separation of different layers, valuable materials such as silver wires, silver paste electrodes, and Cu/Sn ribbons be exposed which is necessary for the extraction the valuable materials.
Can photovoltaic modules' backsheets be recycled?
However, there are few reports on the recycling of photovoltaic modules' backsheets. In this study, we employed customized ultrasonic instrument and compound solvents to recover backsheets from crystalline silicon PV modules.
What is the separation rate of PV panels?
When the reaction temperature is 70 °C, the separation rate of PV panels reaches 100% in 2 h. In contrast, the separation rate at 50 °C and 60 °C is 73% and 86% respectively.
