“…Going by the current expansion of PV technology, the world will see ≈ 78 million tons of solar panel waste by 2050. 128 In addition to the possible waste, the PV modules occupy a lot of space which adds to the cost. To address such issues, research on their recycling (down or upcycling) is already underway 129,130 and alternative fabrication frameworks in the form of thin film plastic solar technologies are already in the market.…”

“…Recently, two major problems facing developing countries, especially in the industrial sector, are electronic solid waste management and the need for more valuable materials due to their enormous consumption [ 1 , 2 , 3 ]. One of the overgrown industries is the renewable energy sector; the generation of global photovoltaic panel (PV) electricity reached 855.7 TWh in 2020, while the installation capacity reached around 707.5 GW and is expected to reach 14.5 TW by 2050 [ 4 ]. Moreover, the global production of photovoltaic panels is expected to multiply [ 5 ].…”

Recovery of Valuable Materials from End-of-Life Photovoltaic Solar Panels

The disposal of end-of-life (EOL) photovoltaic solar panels has become a relevant environmental issue as they are considered to be a hazardous electronic waste. On the other hand, enormous benefits are achieved from recovering valuable metals and materials from such waste. Eventually, physical and chemical processing will become the most important stages during the recycling process. A physical treatment including crushing, grinding, and screening was achieved, and it was observed that a fine fraction of −0.25 mm had the maximum percentage of the required materials. Moreover, the optimum chemical treatment conditions were adjusted to reach the maximum recovery of silver, aluminum, and silicon. The synthesis of silicon oxide, silver oxide, alunite, and K-Alum from leachant solution was performed through a simple route. The structural and morphological properties of the prepared materials were defined by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and field emission scanning electron microscopy (FESEM).

“…Regarding the recycling of Ag from PV, some research has been conducted with crystalline silicon PV technology instead. Many researchers have used high HNO 3 concentrations (at least 40%), as single or multi-compound solutions, and usually high temperatures as well (80 • C) [24][25][26][27]. Łażewska et al [28], on the other hand, investigated the etching of Ag using only 1-3 M nitric acid at 30 and 50 • C. However, it is not clear what yields were achieved for each case.…”
