By utilizing a 1064 nm near-infrared optical-fiber pulsed laser, a laser irradiation followed by mechanical peeling method was demonstrated to recycle the back EVA layer on the solar cells in c-Si PV module.
The proposed hot knife technique effectively separated and recovered the back sheet layer from silicon-based photovoltaic (PV) panels. This method stands out for its environmental friendliness, fastness and efficiency. A key aspect is its ability to recover the high-purity back sheet layer while preserving its integrity.
The initial step in these PV panel recycling processes involves the removal of organic components to free standard and valuable materials. Thermal treatment is the main method employed for this specific purpose. Wang et al., involves a two-stage heating process.
The PV back sheet much stiffer than the encapsulant, serves as an integral component to protect the backside of the PV module. This component has an average thickness of around 0.3 mm . Constituted as composite structures and are manufactured using different layers of materials that include polymers, and adhesives.
