SEMCO Technologies offers tunnel furnaces specifically designed for the elaboration and optimization of thin film photovoltaic absorbers - e.g. CIG (S,Se) chalcogenides.

Our TFPV tunnel furnace technology is based on innovative and flexible software-controlled single-substrate RTP/evaporation processes dedicated to the atmospheric-pressure selenization, sulphurisation, crystallization and soft cooling of electrodeposited or magnetron sputtered Cu-In-Ga multi-layer thin films on soda-lime glass sheets and metal foils (300-mm wide). Our processing environment is Oxygen-free and no toxic gas are used. Substrate transport and equipment supervision are fully automated.
