Plasmonic Effect

In this study the influence of the plasmonic effect of gold nanoparticles on the parameters (Voc, Jsc and efficiency) of Au-embedded TiO2-based DSSC solar cells was investigated. The gold nanoparticles were successfully embedded into the TiO2 films by means of vacuum evaporation combined with thermal annealing. A thin Au layer was deposited first on TiO2 film by the thermal evaporation then annealed at a temperature of 400 oC to get nanocomposite films. It was found that the Au nanoparticles were well dispersed on the TiO2 films and their average size changed from 14 nm to 35 nm when the deposited gold layer changed from 3 nm to 8 nm. The surface plasmon resonance (SPR) absorption spectrum of Au@TiO2 films was observed in the wavelength range from 534 nm to 614 nm, depending on the gold nanoparticles size. The Au@TiO2 thin films were used as photo-anode for manufacturing the DSSC solar cells in configuration of FTO/Au@TiO2/(I-/I2-) electrolyte/Pt. The I-V characteristics of the cells were measured under irradiation of the visible light. The results indicate that, the short-circuit current (Jsc) and open-circuit voltage (Voc) of the Au@TiO2 films based solar cell and its efficiency were much improved, due to a contribution of the surface plasmon resonance (SPR) effect

Solution processed TiO2 anatase film was used as sensitive layer for H2 detection for two plasmonic sensor configurations: A grating-coupled surface plasmon resonance sensor and a localized surface plasmon resonance sensor with gold nanoparticles. The main purpose of this paper is to elucidate the different H2 response observed for the two types of sensors which can be explained considering the hydrogen dissociation taking place on TiO2 at high temperature and the photocatalytic activity of the gold nanoparticles.
