Ag-encapsulated Au plasmonic nanorods for enhanced dye-sensitized solar cell performance

Abstract

In this article, Ag-encapsulated Au nanorods (Au@Ag NRs) are prepared and introduced into dye-sensitized solar cells (DSSCs).

Plasmon‐Induced Broadband Light‐Harvesting for Dye‐Sensitized Solar Cells Using a Mixture of Gold Nanocrystals

“…The relative enhancement in the optical absorption (ΔOA/OA) of the various photoanodes was calculated (Figure b) . The ΔOA/OA of the TiO 2 film that contains the AuNCs@SiO 2 mixture exhibits three bands in accordance with the plasmonic peaks of the AuNCs@SiO 2 mixture.…”

“…The higher the concentration of AuNCs@SiO 2 , the lower the J sc of the devices. This result can be attributed to the suppression of recombination between triiodide and electrons in the TiO 2 network and thus results in an increased J sc …”

Recent advancements in plasmon-enhanced promising third-generation solar cells

“…At higher metal NP concentrations, a negative shift of the conduction band of metal oxide reduces the driving force for the transfer of photoexcited electrons from the dye to the metal oxide resulting in less efficient electron injection. In the case of anisotropic metal NPs, the optimum concentration of metal NPs for the best PV performance was found to be much higher than 0.2 wt% and to depend on the specific shape of the anisotropic metal NPs [59].…”

Electroless deposition of Ag through-void arrays for integrated extraordinary optical transmission-based plasmonic sensing and surface-enhanced Raman scattering

“…Because plasmon produces near-field electromagnetic fields confined at subwavelength region near the surface, this unique phenomenon enables a series of applications such as surface-enhanced spectrum [2], solar energy utilization [3], and subwavelength optics [4]. Among, plasmonic sensing [5,6] and surfaced-enhanced Raman scattering (SERS) [2,7] are two typical, widely used examples, but their basic research is still attracting much interest.…”
