Pyrolysis and gravimetric separation methods are the most effective, which recovered 91.42 %and 94.25 % silver from crystalline panels and 96.10% silver from CIS PV panels. Yang et al. (2017) used methane sulphonic acid (MSA) with an oxidation agent (hydrogen peroxide) to extract silver from photovoltaic panels.
Recycling Si in waste c-Si PV panels is critical for resource reuse and environmental preservation. Electrostatic separation is a non-polluting and low-cost technology for recovering Si from mechanical crushing products of c-Si PV panels.
Two new technologies are demonstrated to enable the proposed recycling process. One is sequential electrowinning which allows multiple metals to be recovered one by one from Si modules, Ag, Pb, Sn and Cu. The other is sheet resistance monitoring which maximizes the amount of solar-grade Si recovered from Si modules.
Herein, a potential sustainable development idea was put forward to recover silicon materials from stripped discarded photovoltaic modules based on wet leaching and nano-metal catalyzed etching to prepare porous silicon/carbon (PSi/Li/N@C) composite materials for the anode of lithium-ion batteries (LIBs).
