RESOLVED - Recovery of Solar Valuable Materials, Enrichment and Decontamination

  • The use of renewable energy technologies, such as photovoltaics (PV) should be sustainable and environmentally compatible and therefore protect the environment from risks and damaging impacts. Regarding the growing number of installed photovoltaic systems, the end-of-life management of the pv-modules will become increasingly important. Thin film panels contain hazardous substances that may harm the environment if they are not recycled or disposed properly after reaching the end of their service life. Heavy metals, for example, can be toxic as well as carcinogenic or teratogenic. Processing methods for the recycling of PV thin film modules have to take these facts into account. Currently the available recycling techniques usually utilise chemicals such as acids for a wet-chemical treatment of end-of-life modules. The aim of RESOLVED was to identify and test alternative methods for a wet-mechanical treatment in order to reduce the consumption of chemicals in the recycling of thin filmThe use of renewable energy technologies, such as photovoltaics (PV) should be sustainable and environmentally compatible and therefore protect the environment from risks and damaging impacts.

The aim of RESOLVED was to identify and test alternative methods for a wet-mechanical treatment in order to reduce the consumption of chemicals in the recycling of thin film modules. Furthermore, the recovered Cadmium-Telluride (CdTe) and Copper-Indium-Diselenide/Disulfide (CIS) should be helping to save scare resources especially for limited elements such as tellurium and indium. The project RESOLVED investigated the recovery of semiconductors material as secondary raw material and the decontamination of the residues of the PV thin film modules. These goals were achieved by testing and optimising existing technologies for the recycling process as well as for the enrichment of the semiconductor materials. The target is to re-use the enriched recovered material in the production of new PV modules. Special efforts were made to look into life cycle analysis, process sustainability, economical aspects, and resource availability.zeige mehrzeige weniger
