A variety of undesired effects may arise depending on the specific growth mechanism of each material, for instance a percolation threshold thickness is present in Volmer-Webber growth of materials such as silver. In this paper, we explore the introduction of aluminum in silver films as a mechanism to grow ultrathin metallic films of high transparency and low sheet resistance, suitable for many optoelectronic applications. Furthermore, we implemented such ultra-thin metallic films in Dielectric/Metal/Dielectric (DMD) structures based on Aluminum-doped Zinc Oxide (AZO) as the dielectric with an ultra-thin silver aluminum (Ag:Al) metallic interlayer. The multilayer structures were deposited by magnetron sputtering, which offers an industrial advantage and superior reliability over thermally evaporated DMDs. Finally, we tested the optimized DMD structures as a front contact for n-type silicon solar cells by introducing a hole-selective vanadium pentoxide (V2O5) dielectric layer. 2020-11-02T11:24:24Z 2020-11-02T11:24:24Z 2020-10-31 2020-11-02T11:24:24Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.3390/ma13214905 Materials, 2020, vol. 13, num. 21, p. 4905 https://doi.org/10.3390/ma13214905 cc-by (c) Tom, Thomas et al., 2020 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess MDPI Articles publicats en revistes (Física Aplicada)
