Recycling process for CdTe/CdS thin film-solar cell modules in which the modules are mechanically disintegrated into module fragments, the module fragments are exposed to an oxygen-containing atmosphere at a temperature of at least 300&deg; C. causing a pyrolysis of adhesive material contained in the module fragments in form of a hydrocarbon based plastics material and the gaseous decomposition products that are generated during the pyrolysis are discharged, and, afterwards, the module fragments freed from the adhesive means are exposed to a chlorine-containing gas atmosphere at a temperature of more than 400&deg; C. causing an etching process wherein the CdCl and TeCl that are generated in the etching process are made to condense and precipitate by cooling.
