At present, the recycling of PV glass waste is still in its infancy and the products are mostly degraded. Glass waste can be used as part of the raw materials for concrete, white foam glass, and asphalt . However, the addition of glass waste can negatively affect the mechanical properties of a product .
In general, PV glass waste and SKW are recycled using different methods. In the current work, an original method was presented for simultaneously recycling both types of PV waste. The effects of SiO 2 surface-layer removal and silicon separation from SKW were studied.
The increasing amount of PV waste has caused serious environmental pollution and waste of resources, , ; it has become a new major hazard. Therefore, critical technologies for clean and efficient PV waste recycling are urgently required. Recycling silicon from SKW significantly reduces energy consumption and carbon emissions.
Global cumulative installed PV capacity reached 734 GW in 2020, and it continues to grow at an annual rate of 8.9% . Solar PV will be the dominant renewable energy source in the future. However, the rapid development of the PV industry has inevitably generated an immense amount of PV waste.
However, the development of recycling protocols for thin-film PV technologies remains in nascent phases, with limited optimization of recovery processes. The First Solar (US based PV manufacturer) implements a self-contained recycling initiative for their CdTe PV modules, managing the end-of-life (EOL) phase internally.
In conclusion, the present investigation envisaged the recycling process which may be adopted along with neutralization treatment for recovery of TCO-coated glass from waste CdTe PV modules at larger scale, a step towards safe waste management in the frame of circular economy approach.
