“…23 In solar cell fabrication, the efficiency of the cell can be improved by utilizing the plasmonic metallic/ bimetallic NPs which scatter the light efficiently and trap optical energy through SPR. 24,25 Our earlier works on ULAL focused on optimizing the generation of NPs and NSs by changing the surrounding liquid, 5 scanning parameters, 6 input angle of incidence, 7 the shape of input laser pulses, 8 etc. A few of the earlier reports suggested the fabrication of Ag−Au NPs (a) based on post irradiation of colloidal mixtures by laser pulses inducing an alloying process, 16 which was reported to occur through core− shell intermediates 18 (b) entailing ablation of silver targets in the presence of gold nanoparticles.…”

Hybrid silver−gold targets were achieved by effortless mixing of pure silver (Ag) and gold (Au) metals at different ratios (Ag 0.65 Au 0.35 , Ag 0.5 Au 0.5 , and Ag 0.35 Au 0.65 ) and embracing a manual melting process. The obtained targets were ablated by ultrafast (∼40 fs) laser pulses in acetone ensuing the fabrication of Ag−Au bimetallic nanoparticles (NPs) and nanostructures (NSs) in a single experiment. UV−visible extinction spectra of Ag−Au colloids demonstrated the tuning of localized surface plasmon resonance (LSPR) in the spectral range of 406−524 nm. The morphologies of NSs were investigated by the field emission scanning electron microscopy (FESEM) technique. Ag−Au NPs and NSs were utilized as surface enhanced Raman scattering (SERS) platforms to detect secondary explosive molecules such as 1,1-diamino-2,2-dinitroethene (FOX-7, 5 μM concentration) and 1-nitro pyrazole (1NPZ, 20 nM concentration). Our experimental observations clearly demonstrated that the increment in gold percentage reduced the surface activity of Ag−Au NPs/NSs. The estimated enhancement factors (EFs) from the SERS data were typically >10 8 . Our detailed investigations revealed that the NPs and NSs of Ag 0.65 Au 0.35 exhibited significant EFs compared to other ratios and pure metals of Ag and Au. ■ INTRODUCTIONFabrication of pure plasmonic metal (Au, Ag, and Cu) nanoparticles (NPs) achievable through sophisticated chemical methodologies is well established and understood by the scientific community. However, many of these methods demands hours of monitoring and post production processes such as cleaning the nanomaterials to remove chemical dopants and impurities. Similarly, shape controlled production of bimetallic NPs through utilizing surfactants and reagents is also well-known in chemical methods. Many of the earlier reports revealed that bimetallic (Au−Ag, Ag−Cu, and Au−Cu) NPs were fabricated by adding individual colloidal solutions of gold, silver, and copper with different proportions to achieve hybridization of the localized surface plasmon resonances (LSPRs). Ultrafast laser ablation in liquids (ULAL) is a clean, green method which does not utilize chemicals for fabrication of NPs/NSs, and importantly, it does not necessitate extreme cleaning of NPs/NSs. Moreover, simultaneous fabrication of NPs and NSs is possible in the ULAL technique 1−15 in contrast to other chemical methods. Even though some of the solution (chemical) methods are fast (in terms of time taken) compared to various ablation techniques, the main problem with them is that the capped ligand molecules sit on surface of NPs and thus blocks the analyte molecules to achieve direct contact with NP surface. The main objective of fabricating alloy nanomaterials is to find out the exact proportion of individual metals, which exhibits superior performance (in this case, our interest is in the surface enhanced Raman signal) and, hence, are versatile and compatible in many fields such as biomedicine, spectroscopy, and photonics. For example, it has been demonstrated th...

“…The resonance of most metallic nanoparticles is in the visible or infrared regions of the electromagnetic spectrum; however, this also depends on size, shape, and spacing of the metallic particles as well as the dielectric properties of the surrounding medium [ 5 - 7 ]. Most previous studies have shown that silver (Ag) and gold (Au) nanoparticles (NPs) can be used in bulk wafer-based C-Si solar cells or thin-film Si solar cells where the NPs are deposited on one surface of the solar cells [ 1 , 3 , 4 , 8 - 12 ]. However, few studies have examined the effects of metallic NPs deposited on the front and back surfaces of a thin Si solar cell [ 13 ].…”

This study characterized the plasmonic scattering effects of indium nanoparticles (In NPs) on the front surface and silver nanoparticles (Ag NPs) on the rear surface of a thin silicon solar cell according to external quantum efficiency (EQE) and photovoltaic current–voltage. The EQE response indicates that, at wavelengths of 300 to 800 nm, the ratio of the number of photo-carriers collected to the number of incident photons shining on a thin Si solar cell was enhanced by the In NPs, and at wavelengths of 1,000 to 1,200 nm, by the Ag NPs. These results demonstrate the effectiveness of combining the broadband plasmonic scattering of two metals in enhancing the overall photovoltaic performance of a thin silicon solar cell. Short-circuit current was increased by 31.88% (from 2.98 to 3.93 mA) and conversion efficiency was increased by 32.72% (from 9.81% to 13.02%), compared to bare thin Si solar cells.

Surface plasmon resonance could increase the efficiency of solar cells , when light is trapped by the noble metallic nanoparticles arrangement at and into the silicon solar cell (SSC) surface. Pure noble metal (silver and gold) nanoparticles (NPs) have been synthesized as colloids in de-ionized water (DW) by pulsed laser ablation (PLA) process at optimum laser fluence. Silicon solar cell with low efficiency was converted to plasmonic silicon solar cell by overcasting deposition method of silver nanoparticles on the front side of the SSC. The performance of plasmonic solar cell (PSC) was increased due to light trapping. Two mechanisms were involved : inserting silver nanoparticles (Ag NPs) inside the silicon layer by the heating effect of pulsed laser and depositing gold nanoparticles (Au NPs) on the surface of the SSC by overcasting method. The optical properties of silver and gold colloidal solutions were studied with UV- Visible spectrophotometer with a range from 190 nm to 1100 nm. The absorption spectra showed single absorption peak located at about the characteristic value for silver and gold nanoparticles due to the surface plasmon resonance. Atomic Force Microscope (AFM) images were studied , the ablated noble NPs by pulsed laser have an average diameter less than 100 nm. AFM images showed the morphology of SSC surface without and with nanoparticles before and after overcasting and heating by laser methods. Electrical measurements for SSC namely current – voltage ( I-V )characteristics and responsivity (Rλ) displayed higher efficiency after these procedures. The efficiency rise to(5.2%) due to the localized surface plasmons excitation of (Ag NPs) that were embedded into the silicon layer by the heating effect of pulsed laser. The deposition of AuNPs on the silicon surface of the plasmonic SC additionally increased the efficiency to (7.28%), due to light trapping by scattering from Au NPs towards the plasmonic solar cell depth .
