The small-scale test data have a limited guiding effect on industrial purification and cannot guarantee the purification effect and silicon-recovery rate. Therefore, the recovery and purification technologies of metals in crystalline-silicon solar cells need to go beyond the laboratory and further towards the development of industrial application.
Therefore, the recovery and purification technologies of metals in crystalline-silicon solar cells need to go beyond the laboratory and further towards the development of industrial application. The mechanical treatment method uses physical methods, such as crushing and sorting, to separate the components and then reuse them.
