Recycling of photovoltaic modules concerns mainly silicon (Si) and Silver (Ag). Silicon (Si) is around 3.65% and the removal of silicon (Si) comprises many energy-intensive processes. Silver (Ag) is the most costly element used in a solar cell but the quantity is < 1% .
Wei-Sheng Chen et al., reported the recycling of photovoltaic solar cells by leaching and extraction process. The silicon cell consisted of 90% of Si, 0.7% of Ag, and 9.3% of Al. 4 M nitric acid was used for the recovery of Si and 1 M hydrochloride acid was used for the recovery of Ag, Al.
Photovoltaic (PV) cells, often known as solar cells, convert solar energy directly into electrical energy. The sun's surface temperature is around 6000 °C and its heated gases at this temperature emit light with a spectrum ranging from ultraviolet to visible to infrared , .
The premise of sufficiently recycling solar cells containing valuable resources from PV modules is to eliminate EVA for bonding glass, solar cells, and backsheet.
There are no government laws requiring photovoltaic (PV) recycling in the United States, and according to the US National Renewable Energy Laboratory (NREL), only around 10% of decommissioned panels get recycled.
The EPBT of module made by virgin silicon (Si) wafer is more than double compared to recycled one . It is estimated that $ 16–17 revenue can be achieved by recycling materials contained in a typical 60-cell photovoltaic module. In the process of recycling, silver (Ag) will generate the most revenue, followed by aluminium (Al) .
