enhanced absorption in Au Nanoparticles a si h c si heterojunction solar cells exploiting Au surface plasmon resonance
Solar Energy Materials and Solar Cells, 2009Co-Authors: Maria Losurdo, Maria M Giangregorio, G V Bianco, Alberto Sacchetti, P Capezzuto, Giovanni BrunoAbstract:Abstract Au Nanoparticles (NPs)/(n-type)a-Si:H/(p-type)c-Si heterojunctions have been deposited combining plasma-enhanced chemical-vapour deposition (PECVD) with Au sputtering. We demonstrate that a density of ∼1.3×10 11 cm −2 of Au Nanoparticles with an approximately 20 nm diameter deposited onto (n-type)a-Si:H/(p-type)c-Si heterojunctions enhance performance exploiting the improved absorption of light by the surface plasmon resonance of Au NPs. In particular, Au NPs/(n-type)a-Si:H/(p-type)c-Si show an enhancement of 20% in the short-circuit current, J SC , 25% in the power output, P max and 3% in the fill factor, FF, compared to heterojunctions without Au NPs. Structures have been characterized by spectroscopic ellipsometry, atomic force microscopy and current–voltage ( I – V ) measurements to correlate the plasmon resonance-induced enhanced absorption of light with photovoltaic performance.

plasmon enhanced photoelectrochemical water splitting using Au Nanoparticles decorated on hematite nanoflake arrays
Chemsuschem, 2015Co-Authors: Lei Wang, Xuemei Zhou, Nhat Truong Nguyen, Patrik SchmukiAbstract:Hematite nanoflake arrays were decorated with Au Nanoparticles through a simple solution chemistry approach. We show that the photoactivity of Au-decorated Fe2 O3 electrodes for photoelectrochemical water oxidation can be effectively enhanced in the UV/Visible region compared with the bare Fe2 O3 . Au-nanoparticle-decorated Fe2 O3 nanoflake electrodes exhibit a significant cathodic shift of the onset potential up to 0.6 V [vs. reversible hydrogen electrode (RHE)], and a two times increase in the water oxidation photocurrent is achieved at 1.23 VRHE . A maximum photocurrent of 2.0 mA cm(-2) at 1.6 VRHE is obtained in 1 M KOH under AM 1.5 (100 mW cm(-2) ) conditions. The enhancement in photocurrent can be attributed to the Au Nanoparticles acting as plasmonic photosensitizers that increase the optical absorption.

photocatalytic activity of tio2 nanotube layers loaded with ag and Au Nanoparticles
Electrochemistry Communications, 2008Co-Authors: Indhumati Paramasivam, Jan M Macak, Patrik SchmukiAbstract:Abstract Ag and Au Nanoparticles were found to significantly enhance the photocatalytic activity of self-organized TiO 2 nanotubular structures. The catalyst systems are demonstrated to be highly efficient for the UV-light induced photocatalytic decomposition of a model organic pollutant – Acid Orange 7. The metallic Nanoparticles with a diameter of ∼10 ± 2 nm (Ag) and ∼28 ± 3 nm (Au) were attached to a nanotubular TiO 2 layer that consists of individual tubes of ∼100 nm of diameter, ∼2 μm in length and approx. 15 nm of wall thickness. Both metal particle catalyst systems enhance the photocatalytic decomposition significantly more on the nanotubes support than placed on a compact TiO 2 surface.
