Driven by global energy transition and environmental protection, the PV industry is booming worldwide. However, as an increasing number of polysilicon PV modules reach the end of their lifespan, the need for intensive research and development in recycling technologies is becoming increasingly urgent.
This is because polysilicon PV modules require significante consumption of fossil fuels, particularly electricity, and emit large amounts of GHGs throughout their lifecycle.
