Luminescent Solar Concentrator (LSC), is a device that consists of a transparent
surface (window) in which the solar radiation impacts. Most of the incident
radiation is transmitted but another part is trapped by total internal reflection
and is redirected to the sides of the window where a conventional solar cell is
placed. One strategy to optimize this type of device is to sensitize it with
photoluminescent dyes. In this work we present results of the increase of the
efficiency of a CSL sensitized with Rhodamine-6G, by means of the plasmonic
effect produced by gold nanoparticles (Au-NP). The Au-Np, were synthesized by
the reduction method obtaining NP with average diameter of 80 nm, and coated
with a layer of SiO2 under the Stober method. The dye (Rhodamine) and the Au-
NP were incorporated into a PMMA matrix and subsequently deposited as a film
on the surface of the substrate. The characterization was carried out by
irradiating the samples in a solar simulator, the results show up to 5% gain in
the photoconversion efficiency in the devices with gold nanoparticles
