One of the technical challenges with the recovery of valuable materials from end-of-life (EOL) photovoltaic (PV) modules for recycling is the liberation and separation of the materials. We present a potential method to liberate and separate shredded EOL PV panels for the recovery of Si wafer particles.
In this paper, an innovative research was first reported by using microwave enhancement methods to efficiently separate PV panels. Firstly, suitable solvent was selected by comparing the static separation effect of PV panels in different solvents.
Recycling solar photovoltaic panels to recover materials, especially silicon, is a critical sustainability challenge. Recovering materials from waste for use in manufacturing new products can significantly reduce the demand for virgin materials, offering notable environmental and economic benefits (A. Paiano, 2015) (Cucchiella and Dadamo, 2012).
In the present study, a two-stage heating treatment was conducted to separate the waste crystalline silicon solar panels. The TPT backing material could be recovered integrally by heating at 150 °C for 5 min, which was conducive to further recycling and regeneration.

6 FAQs about [Photovoltaic panel material 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.
How does electrostatic separation affect waste silicon photovoltaics?
Electrostatic separation has an influence in most of the materials present in waste silicon photovoltaics. This process may assist in the recycling of waste PV.
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.
Why did electrostatic separation fail in photovoltaic panels?
Electrostatic separation was not able to concentrate the polymers present in photovoltaic panels. The presence of PVC as one of the polymers present in photovoltaic panels may have contributed to the failure of the electrostatic separation method [15, 29].
Can electrostatic separation segregate the metallic fraction of photovoltaic panels?
Moreover, the mass distributions in the three pans as a function of the tested parameters are shown in Supplementary Table 7. The key conclusions from this study are as follows: Electrostatic separation is able to segregate the metallic fraction of waste photovoltaic panels. Metals tend to concentrate in the first separation fraction (conductor).
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.
