Shin et al. (2017) recovered silicon from EOL solar panels and fabricated lead-free silicon solar panels in three steps. In the first step, nitric acid (HNO 3) and potassium hydroxide (KOH) were used to dissolve silver and aluminium, respectively.
Recycling process of silicon from PV panels. Etching solutions needed to be modified as per the kind of PV cells to be recycled. The addition of surfactants improved recovery rate of silicon. Huge loss of silicon during NaOH chemical etching process. Partial loss of silicon during the etching process.
Gao, S., Chen, X., Qu, J. et al. Recycling of silicon solar panels through a salt-etching approach.
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.
Silicon solar cells were recovered at a 100% rate when treated for 3 h in a muffle furnace kept at 200 °C. In comparison to benzene and trichloroethylene, KOH-ethanol demonstrated a superior recovery rate with lower environmental emissions. 4.4. Methods of recycling silicon wafers and recovery of silicon
