CuSiO2/Cu-cermet selective absorbers for solar photothermal conversion

A review of cermet-based spectrally selective solar absorbers

“…The metals Cu, Ag, Au, Ni and Mo embedded in SiO 2 media have been investigated as spectrally selective coatings. [70][71][72][73][74] Cu-SiO 2 cermets prepared by simultaneous evaporation of silicon dioxide and copper with an electron beam heater and electricresistance heater, respectively, were used as absorption layers for spectrally selective absorbers by Garnich et al 72 The lling factor of the metal in the dielectric matrix and the thickness of the cermets can directly determine the spectral selectivity of the coatings. The transition wavelength can be adjusted by changing the lling factor and thickness of the cermet layer.…”

BiFeO3 perovskite-based all oxide ambient stable spectrally selective absorber coatings for solar thermal application

“…The vast variety of the materials explored as SSACs include Zr-ZrO 2 , Cr-Cr 2 O 3 , Ni-Al 2 O 3 , Cu-SiO 2 , Ag-CuO, Ni-Fe 3 O 4 , Co 3 O 4 , Fe 2 O 3 , MoO x , CuMn 2 O 4 , SiO 2 /(ZnO/Sn-In 2 O 3 )/SS, etc. [18][19][20][21][22][23][24][25][26][27][28] Recently, cermets emerged as an efficient SSAC with excellent absorptance and optical properties, which can be easily modulated by alloying them or using them in multilayer combinations. Cao et al reported an excellent absorbance of 0.9 with better thermal stability on Ni-Al 2 O 3 -W-Ti-Al 2 O 3 alloy coatings.…”

Co‐sputtering of A Thin Film Broadband Absorber Based on Self‐Organized Plasmonic Cu Nanoparticles

“…The materials considered in metal-dielectric composite absorbers are, e.g., Cu and Au in a SiO 2 matrix or W, [18,21,22] TiN, [23] Ag, [24] and Cu in an Al 2 O 3 matrix. [3,19,25] In order to enhance the thermal stability of metal-dielectric composite coatings, additional metal, metal oxide or metal nitride thin films have been investigated as diffusion barriers.…”
