Disposal of photovoltaic thin-film components
Cadmium and tellurium, comprising the core photovoltaic material in thin-film modules, are successfully extracted and purified for reuse. These recovered materials can be reprocessed into new solar panels, maintaining their essential role in the circular economy. . Thin-film solar cells present unique recycling challenges due to their complex layered structure and trace amounts of valuable materials. Current installations contain approximately 5-12g of silver and 3-4g of copper per square meter, along with semiconducting compounds like cadmium telluride. . These thin film solar panels account for 21% of the U. Unlike traditional silicon panels, CdTe technology depends on elements that are byproducts of copper and zinc mining operations. Recycling. . ANTEC Solar has developed a patented process for recycling CdTe and CdS thin-film PV modules by treating the modules in a gaseous environment[44 ]; this proves is distinct from the other chemical etching processes where wet chemicals are used.
