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.
A sustainable method for reclaiming silicon (Si) wafer from an end-of-life photovoltaic module is examined in this paper. A thermal process was employed to remove ethylene vinyl acetate and the back-sheet. We found that a ramp-up rate of 15 °C/min and an annealing temperature of 480 °C enabled recovery of the undamaged wafer from the module.
Metal electrodes, anti-reflection coatings, emitter layers, and p-n junctions must be eliminated from the solar cells in order to recover the Si wafers. In this study, we have carried out the etchant HF + H 2 O 2 + CH 3 COOH wet chemical etching methods to selectively recover Silicon wafers from end-of-life Silicon solar cell.
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.
Ultimately, silicon wafer recovery is indispensable for the solar panel industry, facilitating efficient resource usage, extending product lifespan, and improving overall performance.
The recovery of silicon wafers is integral to the sustainable production of solar panels, as these panels heavily rely on high-quality silicon substrates to efficiently convert energy.
