“…These properties make GNPs favourable for innumerable applications in medical, electronics, materials science, alternative energy generation, environmental restoration, etc. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Available methods for nanoparticle synthesis use toxic chemicals either in the form of reducing agents to reduce various metal salts to their corresponding nanoparticles or as stabilizing agents to prevent nanoparticles from agglomeration [16][17][18].…”

This report describes the use of ethnolic extract of Fagopyrum esculentum leaves for the synthesis of gold nanoparticles. UV-visible spectroscopy analysis indicated the successful formation of gold nanoparticles. The synthesized nanoparticles were characterized by transmission electron microscopy (TEM), high resolution TEM (HRTEM) and were found to be spherical, hexagonal and triangular in shape with an average size of 8.3 nm. The crystalline nature of the gold nanoparticles was confirmed from X-ray diffraction (XRD) and selected-area electron diffraction (SAED) patterns. Fourier transform infrared (FT-IR) and energy-dispersive X-ray analysis (EDX) suggested the presence of organic biomolecules on the surface of the gold nanoparticles. Cytotoxicity tests against human HeLa, MCF-7 and IMR-32 cancer cell lines revealed that the gold nanoparticles were non-toxic and thus have potential for use in various biomedical applications.

“…In the last decade, the use of plasmonic metal nanoparticles (NP) to enhance the light absorption of silicon solar cell has attracted much attention. The more effective optical absorption is caused by scattering from the metallic nanoparticles [1]. The incident light interacts with the metal NP very effectively by coupling surface Plasmon [2] over cross sections much larger than the NP's geometrical cross section [3].…”

Photovoltaic (PV) power is a promising choice as low-cost, environmentally friendly energy source. Thin-film solar cell is proposed as an alternative to reduce the cost due to its very thin silicon absorbers and utilization of cheap substrates. However because of the thin thickness of thin film solar cell, the light absorption is poor. In order to increase the absorption efficiency, surface plasmonic effect is used to improve the optical absorption. In this paper, we firstly attempt to use alloy to increase the light absorption. The results show Al-Cu alloy gives a better performance of absorbing light especially in the long wavelength region. We also build a nano-hole / embedded particle structure which can increase the absorption of the long wavelength light as well. In the end, we recommend using alloy material and the hole-particle surface plasmonic structure with a good back reflector in order to have a higher absorption of light to achieve a better performance thin film solar cell.

“…Nakayama et al carried research on Ag nanoparticles for improving light absorption in GaAs solar cells, which demonstrated that the efficiency was enhanced by 5.9% [11]. The above-mentioned experiments show that SPs are an effective way for light trapping [12]. However, little theoretical work has been carried out to quantify the effectiveness of plasmonic light trapping structure, especially to evaluate the effectiveness of light trapping over the full spectrum.…”

In order to enhance light absorption of thin film poly-crystalline silicon (TF poly-Si) solar cells over a broad spectral range, and quantify the effectiveness of nanoshell light trapping structure over the full solar spectrum in theory, the effective photon trapping flux (EPTF) and effective photon trapping efficiency (EPTE) were firstly proposed by considering both the external quantum efficiency of TF poly-Si solar cell and scattering properties of light trapping structures. The EPTF, EPTE and scattering spectrum exhibit different behaviors depending on the geometric size and density of nanoshells that form the light trapping layer. With an optimum size and density of SiO 2 /Au nanoshell light trapping layer, the EPTE could reach up to 40% due to the enhancement of light trapping over a broad spectral range, especially from 500 to 800 nm. thin film poly-crystalline silicon, surface plasmons, SiO 2 /Au nanoshell Citation: Bai Y M, Wang J, Chen N F, et al.
