Selective Surfaces for Solar Thermal Energy Conversion inCSP: From Multilayers to Nanocomposites

Micro-Nano Surface Functionalization of Materials and Thin Films for Optical Applications

“…As expected, the deposition rate is constant. In contrast to what is known for other TCO materials (see Figure 7b, [56]), the resistivity increases significantly with increasing film thickness, caused mainly by the decrease in the carrier concentration. A similar behaviour was observed by Minami et al and by Brousseau et al for undoped SnO 2 films, also deposited by RF magnetron sputtering [57,58].…”

“…The well-known behaviour of a decreasing resistivity with increasing film thickness can be explained by an increasing grain size and the decreasing effect of surface and interface carrier scattering, described by the Fuchs-Sondheimer theory, see [56,59,60]. The concentration of argon in the films is about 0.4 at% for films deposited at room temperature.…”

Comprehensive study of WSiC:H coatings synthesized by microwave-assisted RF reactive sputtering

“…The materials were developed in the IDEFIX vacuum reactor designed at PROMES-CNRS laboratory [25]. It consists in a cylindrical enclosure on which are placed four coaxial microwave sources of dipolar type (with magnet) which are maintained by water-cooled flanges and connected to a SAIREM GMP16KTS microwave generator operating at 2.45 GHz, which supplies them with a maximum power of 250 W each.…”

Optical Properties of Complex Plasmonic Materials Studied with Extended Effective Medium Theories Combined with Rigorous Coupled Wave Analysis

“…Complex plasmonic systems, and in particular plasmonic nanocomposites, have emerged as promising materials for numerous applications in photonics [ 1 , 2 , 3 ], photovoltaics [ 4 , 5 , 6 , 7 ], and in environmental issues such as water remediation [ 8 , 9 , 10 ] or hydrogen production through water splitting [ 11 , 12 , 13 ]. Indeed, due to their plasmonic features, these systems exhibit novel optical as well as electrical properties.…”
