 The ANR SiNOCH project has made it possible to synthesize, by plasma processes, organosilicon matCOUCHES MINCES Couches minces pour le solaire Thermique Antoineerials of the silicon nitride or carbide type. To this end, the OPTIMIST platform, coupled with an XPS spectrometer, was implemented according to different deposition process configurations. The link between deposition conditions and characteristics (in situ and ex-situ) of the materials has been established. The study is currently continuing with the ANR NANOPLAST (see website) project for the development of thin films for solar energy thermal conversion. Thus, SiC / metal (W) nanocomposite materials are promising candidates as absorbers of solar radiation. The work carried out at IMN focuses on the study by TEM microscopy and XPS spectrometry of the nanostructuring and atomic arrangement of these materials, in relation to the optical properties assessed by ellipsometry.
