Silicon solar cells struggle with the economic viability of recovering Ag – the average quantity being 630 g/ton in silicon solar cell waste (Dias et al., 2016) and the limit of economic viability being 700 g/ton (Nevala et al., 2019). Even large global use does not guarantee that the issues of recycling will be resolved.
The solar PV cells have a lifetime to serve properly, which is about 15–25 years from installation. Solar PV cell has recycling potentiality as well as the risk of producing hazardous wastes. After the end-of-life, the solar panel would turn into waste, specifically e-waste, which might be an environmental concern in the long run.
