Through investigation, this research demonstrates the feasibility and cost-effectiveness of silicon wafer recovery from damaged silicon solar panels. As photovoltaic technology continues to advance rapidly, there is a pressing need for the recycling industry to establish adaptable recycling infrastructure to accommodate evolving industry needs.
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.
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.
In this study, xylene, a sole organic solvent, was employed to detach silicon wafers from damaged solar modules. However, the EVA resin adhered firmly to the silicon wafer, making manual removal difficult. Therefore, a muffle furnace was utilized to heat the silicon adhered with EVA resin at 130 °C for 3 h.
Processes to recycle Si wafer from solar PV module The junction box, aluminium frame and cables have been separated mechanically which are attached with the help of adhesive glue (Silica gel). Mechanical separation is the only method to remove them without damage.
