This paper details an innovative recycling process to recover silicon (Si) wafer from solar panels. Using these recycled wafers, we fabricated Pb-free solar panels. The first step to recover Si wafer is to dissolve silver (Ag) and aluminium (Al) via nitric acid (HNO 3) and potassium hydroxide (KOH), respectively.
For this reason, we are focusing on developing Pb-free solar panels using recycled silicon wafers. The first step to recycle Si wafer is separation of the different layers of the solar panels without damage to the Si wafer. Kang et al. reported a procedure to separate solar panels via toluene.
Globally, end-of-life photovoltaic (PV) waste is turning into a serious environmental problem. The most possible solution to this issue is to develop technology that allows the reclamation of non-destructive, reusable silicon wafers (Si-wafers). The best ideal techniques for the removal of end-of-life solar (PV) modules is recycling.
Ultimately, silicon wafer recovery is indispensable for the solar panel industry, facilitating efficient resource usage, extending product lifespan, and improving overall performance.
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.).
A method for recovering silicon wafers from end-of-life solar panels was investigated. The properties of recycled wafers are almost identical to those of commercial virgin wafers. The conversion efficiency of the remanufactured solar cells fell in the range of 15.0–16.0%. Solar modules, which contain these cells, show good stability.
