“…The optimized doping concentration of the dye and the nanocuboids in the PLSC device was 70 ppm and 1.1 ppm, respectively. The PLSC was optimized by varying the doping concentration of the nanocuboids in the waveguide and studying the emission from the edge of the PLSC waveguide, reported in earlier work [37]. 1.1 ppm nanocuboid doping concentration led to the maximum fluorescent enhancement from the edge of the PLSC.…”

“…The plasmonic interaction parameters have been optimized for different PLSC device designs and different MNP fluorophore combinations [36,37, 48, [49]. 25.8 % [48] and 30% [37] increase in the edge efficiency was reported on indoor testing of a thin film PLSC and a homogeneous PLSC respectively. This study has undertaken a detailed outdoor characterization of PLSC devices to understand the in-depth functionality of PLSC devices and to gain an insight into the role of plasmonic interaction under different solar insolation.…”

Plasmonic Luminescent Solar Concentrators (PLSCs) have been shown to enhance the optical performance and power conversion efficiency of LSCs, due to added plasmonic gain in the medium. Despite the promising outlook of a PLSC through plasmonic coupling, device characterization and performance has not been verified in the real outdoor conditions, with varying direct and diffuse solar irradiation. In this work, characterization of a PLSC device of dimensions 4.5×4.5×0.3 cm 3 embedded with Lumogen Red305 dye and plasmonic gain medium of gold core silver shell nanocuboids was carried out in outdoor conditions of Dublin, Ireland. Optimized PLSC device power output at different solar insolation’s was compared to a reference photovoltaic (PV) cell and an optimized Luminescent Solar Concentrator (LSC) device. The effect of the solar discs position, solar insolation, PV cell surface temperature, diurnal, and seasonal variation on the performance of the PLSC device is studied. The key observation was that PLSC average power conversion efficiency was 1.4 times more than the PV cell in cloudy and diffuse solar conditions. The PLSC device performed 45% better than a PV cell in December than July, as December has higher diffuse solar irradiation. Even though the PLSC device absorbs only 31% and transmits 69% incident solar irradiation in the concerned visible range of 380-750 nm. The preliminary outdoor characterization on a small scale PLSC establishes its viability in a diffuse to direct solar radiation ratio throughout the year as well as establishing its benefits for integration in buildings.

“…A small number of studies have examined the plasmonic scattering of Ag-NPs and the luminescent down shifting (LDS) of Eu-doped phosphors to enhance the conversion efficiency of crystalline silicon solar cells [26,27]. The integration of Ag and Eu-doped phosphors on silicon solar cells has also been shown to enhance conversion efficiency via metal-enhanced fluorescence (MEF) [28][29][30].…”

This paper studied characterized the plasmonic effects of silver nanoparticles (Ag-NPs), the luminescent down-shifting of Eu-doped phosphor particles, and the metal-enhanced fluorescence (MEF) achieved by combining the two processes to enhance the conversion efficiency of silicon solar cells. We obtained measurements of photoluminescence (PL) and external quantum efficiency (EQE) at room temperature to determine whether the fluorescence emissions intensity of Eu-doped phosphor was enhanced or quenched by excitation induced via surface plasmon resonance (SPR). Overall, fluorescence intensity was enhanced when the fluorescence emission band was strongly coupled to the SPR band of Ag-NPs and the two particles were separated by a suitable distance. We observed a 1.125× increase in PL fluorescence intensity at a wavelength of 514 nm and a 7.05% improvement in EQE (from 57.96% to 62.05%) attributable to MEF effects. The combined effects led to a 26.02% increase in conversion efficiency (from 10.23% to 12.89%) in the cell with spacer/NPs/SOG-phosphors and a 22.09% increase (from 10.23% to 12.48%) in the cell with spacer/SOG-phosphors, compared to the bare solar cell. This corresponds to an impressive 0.85% increase in absolute efficiency (from 12.04% to 12.89%), compared to the cell with only spacer/SOG.
