Currently, the primary methods used for recovering Ag from retired PV panels include pyrometallurgical and hydrometallurgical methods (such as nitric acid leaching and cyanide leaching) [16, 26, 27]. . Consumption of photovoltaic solar panels is expected to increase, so the growing amount of end-of-life (EOL) solar panels will require large spaces for their disposal, which at the moment costs around 200 euros/ton. This study developed an environmentally friendly leaching method using ammonia (NH 3 ·H 2 O) and hydrogen peroxide (H 2 O 2), achieving the selective. . A Chinese-Australian research team has used for the first time deep eutectic solvents for separating EVA films for end-of-life PV panels. The result is reportedly a 100% separation rate accompanied by an aluminum removal efficiency of 98. 4% An international research team has proposed to use deep. . Current recycling process tend to focus on recycling only a small number of materials from the module or downcycling the components rather than recycling them.
