The pyrolysis thermal treatment process effectively removes adhesive material and all other materials from the PV panel (Dias et al., 2016). Bohland and Anisimov, 1997 proposed a pyrolysis method to recycle solar PV panels in an inert environment, allowing the recovery of glass, silver, and lead without disposing of them in water.
Li et al. (2022) innovatively proposed the laser irradiation method to gently separate the Ethylene Vinyl Acetate (EVA) layer from the back of solar PV cells. This process ensures the separation without causing damage to the cells and minimizes environmental emissions as shown in Fig. 13.
Physical processes involve mechanical treatments applied to the PV panel, such as shredding and milling (B. Sorensen., 2017) (Granata et al., 2014) (M. Ito, 2016) (Azeumo et al., 2019; Xuefeng et al., 2021).
In the first stage, 20 pulses of around 110 kV separate glass and back sheet solar panels, followed by sieving and dense medium. In the second separation method, the glass layer was crushed to a size fraction of 45–850 μm using 250 pulses at a rate of 90 kV. After separation, there was a 30% increment in silver concentration.
However, efforts have been made to encourage proper disposal and recycling of PV module waste through amendments to the law on renewable energy under the “Act on the Promotion of the Development, Use, and Diffusion of New and Renewable Energy” (Kim et al., 2014).
After separation, there was a 30% increment in silver concentration. Moreover, the processing cost of this method is found to be around 0.0019 $/W, making it an economical solution for recycling PV panels. Zhao et al. (2020) performed a parametric investigation on a high-voltage pulse method to enrich PV panel waste.

In 2011 Pi et al. spin-coated Si NCs onto screen-printed single-crystalline solar cells. The power-conversion efficiency (PCE) of the solar cell was increased by ∼4% after the spin-coating of Si NCs [34].Due to the anti-reflection effect of the Si-NC film, the reflectance of the solar cells was reduced in the spectral range from 300 to 1100 nm.
