ANTEC Solar GmbH has established a pilot-scale facility based
on the CdTe/CdS thin film PV module recycling process patented by Campo [41]. In this process, the modules are firstly physically disintegrated into module fragments. The module fragments are then exposed to an oxygen-containing atmosphere at a tempera- ture of at least 300 °C, causing a pyrolysis of EVA. Afterwards, the module fragments are exposed to a chlorine-containing gas atmosphere at a temperature of more than 400 °C, causing an etching process wherein the CdCl2 and TeCl4 are generated. The generated CdCl2 and TeCl4 are then condensed and precipitated by cooling (see Fig. 5).
