The enhancement effect of optical absorption with core-shell gold nanoparticles on the surface wafer-based silicon photovoltaic devices has been studied. obvious enhanced photocurrent is observed, especially when wavelength above 800 nm, and highest value about 14% around 1100 nm. simulation results indicate that presence dielectric coating shell could improve plasmon based scattering at longer range, which provides a good understanding experiment results.
The optical absorption enhancement in thin film organic solar cells (OSCs) with plasmonic metal nanoparticles (NPs) has been studied by means of finite element method a three-dimension model. It is found that significant above 100% can be obtained introducing Ag-NPs at the interface between P3HT:PCBM active layer and PEDOT:PSS anode layer. This even larger than totally embedded OSCs. Furthermore, mechanism different positions OSCs investigated.

Vanadomolybdates (VMos), comprised of Mo and V in high valences with O bridges, are one the most important types polyoxometalates (POMs), which have activity due to their strong capabilities gaining/losing electrons. Compared other POMs, preparation VMos is difficult relatively low structural stability, especially those unclassical architectures. To overcome this shortcoming, study, triol ligands were applied synthesize through a beaker reaction presence V2O5, Na2MoO4, organic species...
Laser-assisted microanalysis and SXR/XUV-assisted nano-analysis offers the advantage of determining spatially resolved composition in 3D.
Laser-induced breakdown spectroscopy (LIBS) is a rapid in-situ microanalytical technique. Affected by poor precision, due to plasma flicker noise, it has reached its maturity. XUV (LIXS), works similarly LIBS, while collects the stable emission in extreme ultraviolet. Such associated with early stages of laser-plasma. The information capacity spectrometer shown be quadratically increased. Specific electron-ion processes LIXS are discussed, showing how improves limits detection and precision....
The efficiency enhancement of thin film hetero-junction organic solar cells (OSCs) with Au-nanopaticles (Au-NPs) at the interface between anode and active layers is studied theoretically experimentally. It demonstrated that interface-Au-NPs could effectively extend spectrum light absorption based on localized surface plasmon, which revealed by incident photon-to-current photocurrent increased both long (λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The development of extreme ultraviolet (XUV) sources for tabletop operation has enabled a range new applications in nano-structuring and spectroscopy.
The first class of triol-ligand covalently-decorated Keggin-type polyoxomolybdates through C–O–Mo bonds were obtained and characterized.
We demonstrate high-performance broadband tunable external-cavity lasers (ECLs) with the metal-organic chemical vapor deposition (MOCVD) grown InAs/InP quantum dots (QDs) structures. Without cavity facet coatings, 3-dB spectral bandwidth of Fabry–Perot (FP) laser is approximately 10.8 nm, while tuning ECLs 45 nm. Combined anti-reflection (AR) / high-reflection (HR) coating, a 92 nm range has been obtained wavelength covering from 1414 to 1506 In most range, threshold current density lower...
Laser-induced breakdown spectroscopy (LIBS) is a well-established elemental analysis method, thanks to negligible sample preparation, rapid analysis, and spatially resolved sensitivity down trace level, in any kind of matrix. State-of-the-art LIBS operated the optical spectral range (UV-VIS). Unfortunately, measurement precision limited by moderate stability repeatability plasma emission. The detection crucial elements such as light halogens are also limited. This particularly critical for...
Utilizing plasmonic metal nanoparticles is considered as one of the promising methods for increasing conversion efficiency in thin film organic solar cells. However, bare may suffer from energy loss introduced by themselves due to recombination electro-hole pairs. In this paper, optical absorption enhancement cells with metal-dielectric core-shell nano-particles active layer has been proposed and studied. It expected that core could increase absorption, consequently localized surface plasmon...

The enhanced optical absorption in solar cells using nanoscale structure and novel physical effect has received a lot of attention recent years. One the promising methods is to utilize noble metal nanoparticles with plasmonic for increasing light absorption, consequently conversion efficiency photovoltaic devices. While bare may suffer from energy loss introduced by themselves due recombination electro-hole pairs. Here, we propose apply metal-dielectric core-shell nano-particles improve thin...
Development of cost-effective, active trifunctional catalysts for acidic oxygen reduction (ORR) as well hydrogen- and oxygen-evolution reactions (HER OER, respectively) is highly desirable, albeit challenging.
