CIEMAT- Chalcogenide Lab

• Preparation of thin-film chalcopyrite absorbers (CuInSe2, CuIn1-xGaxSe2 and CuIn1-xAlxSe2) by selenization of evaporated metallic precursors.
• Preparation of thin-film chalcogenide windows (In2S3, (In,Ga)2S3 and SnS2) by modulated flux evaporation.
• Preparation of transparent conductive oxides (Al:ZnO, Sn:In2O3 and Sb:SnO2), photofunctional metal oxides (TiO2, N:TiO2) and metallic contacts (Mo, Al, Ni, etc.) by sputtering and evaporation.
• Optoelectronic characterization (I-V curves and spectral photocurrent measurements) adapted to thin-film devices with chalcopyrite or organic absorbers.

MAIN TECHNICAL FEATURES:

• In-line sputtering system with DC, MF and RF sources for metal oxide deposition on 25x25 cm2 areas.
• Static sputtering system with DC and MF sources for metal oxide deposition on 10x10 cm2 areas.               
• Evaporation systems for chalcogenide deposition on 10x10 cm2 areas.
• Optical characterization by spectrophotometry, I-V characterization and spectral response.
