Influence of a Ag Layer on AZO/Ag/AZO Multilayer Thin Films Prepared by Facing Targets Sputtering

Structural, optical and electrical properties of multilayer stacks ZnO:Al/Ag/ZnO:Al and ZrO2/Ag/ZrO2

“…The optical properties of these multilayer stacks with Ag nanograins can be explained with the Mie theory of plasma properties of electrons in the metal with dielectric function ϵ m surrounded by a transparent oxide with dielectric function ϵ oxide .…”

“…a) of as‐deposited and annealed multilayer stacks ZnO:Al/Ag/ZnO:Al and ZrO 2 /Ag/ZrO 2 have two bands, at 365 nm and about 460 nm. The band at about 365 nm is due to d‐shell electrons of the Ag atoms and the near‐lying quadrupolar electron plasma the resonance of the Ag NPs . The value of its full width at half‐maximum (FWHM) in the spectra of the ZrO 2 /Ag/ZrO 2 stack is smaller compared to that of the ZnO:Al/Ag/ZnO:Al stacks.…”

“…This is promising for their application as a back reflector at the rear side of the thin‐film solar cells to improve light harvesting. It has to be noted that the diffuse reflectance of the stacks is influenced by the plasma resonance of Ag NPs, their shape and size distribution .…”

Fabrication of Ag nanowire and Al-doped ZnO hybrid transparent electrodes

“…However, studies of heretofore have failed to satisfy. 3,[7][8][9][10][11][12] Silver nanowires (AgNWs) are strong candidates for transparent conductive electrodes with excellent electrical and optical properties because of the use of nano-sized silver as the main material. However, if the AgNW is fabricated as a thin film, it has shortcomings such as its unstable properties upon heating (200 °C), ease of oxidization in air, and weak adhesion to the substrate.…”
