Y2O3:Eu3+, Tb3+ sphere particles doped anti-reflection and wavelength conversion bifunctional films: Synthesis and application to solar cells

Ji R., Hu X., Tian M., Han L., Jun F., Wang L., Wang Y., Zhan S., Zhang Q., Zhang Q., Wang L., Wang Y., Northwest University, CN

Solar energy, as a clean and sustainable resource, has great potential to take place of the traditional energy source. While the low photoelectric conversion efficiency limits the application of solar cells to a great extent. [...]

Deposition of TiO2/Ni/CuO/ITO multi-layered cell for solar-driven water splitting

Wu K.R., National Kaohsiung Marine University, TW

In this study, a photoelectrolysis cell based on multilayered TiO2/Ni/CuO (M-cell) photoelectrode is prepared on ITO substrate (110 nm thick) using a multi-target direct current and radio-frequency magnetron sputtering technique in which Ni acts as [...]

XRD and SEM studies on annealed nanocrystalline titanium dioxide powder

Babkair S.S., Ansari A.A., Al-Qurashi N.N., King Abdulaziz University, SA

Anatase phase of nanocrystalline (nC) titanium dioxide in photo-catalysis, photo-splitting of water to produce hydrogen and as electrode material in Dye Sensitized Solar Cells (DSSCs)is mostly used due to its higher band gap. However, recent [...]

Transfer of asymmetric free-standing TiO2 nanowire films for high efficiency flexible dye-sensitized solar cells

Xue Z., Wang L., Liu B., National University of Singapore, SG

A free-standing TiO2 nanowire thin film was prepared using the doctor-blade method. The film is composed of big and small nanowires on each side. The big nanowires have the functions of weakening adhesion to its [...]

CeF3 Fullerene-like Nanoparticles: Synthesis, Upconversion Properties and Application in Photocatalysis Reduction of CO2

Hou W., Fan J., Hu X., Liu E., Wu F., Yang Y., Kang L., Zhang Q., Sun X., Northwest University, CN

As one of the rare-earth fluorides, Cerium fluoride (CeF3) has been used as host materials, solid lubricants and inorganic fluorescent materials. Among various CeF3 nanostructures, fullerene-like structure (IF) with the hollow cavities inside have attracted [...]

Photocatalytic Performance of Cu/TiO2-xNx Nanotube Arrays Enhanced by Surface Plasmon Resonance and Application in Hydrogen Evolution by Water Splitting

Kang L., Liu E., Hu X., Fan J., Fan X., Wu F., Wu H., Fan J., Fan X., Hou W., Wu F., Wu H., Wang Q., Northwest University, CN

Studies revealed that noble metal (Au, Ag, Pd) nanoparticles can improve the photoresponse property of TiO2 in the visible region based on the surface plasmon resonance (SPR) effect, and enhance the activity of TiO2 photocatalyst. [...]

A Generalized Model for Global Solar Radiation in South Africa Using Multiple Weather Elements as Predictors

Enweremadu C.C., Adeala A.A., Huan Z., University of South Africa, ZA

In this study a generalized model for predicting global solar radiation was developed for South Africa. This was achieved by employing easily measured weather elements like sunshine hour, ambient temperature, relative humidity and wind speed [...]

Plasmonic Enhanced Light Trapping in a P3HT Photovoltaic

Shepard S., BakshiGupta D., St. Luce G., Louisiana Tech University, US

We consider the enhancement of an organic (P3HT) photovoltaic with conductive nanoparticles of various shapes, sizes and spacing as top-reflectors; used in conjunction with a periodic and a pseudo-random back-reflector. The surface for the pseudo-random [...]

Solar automated greenhouse

Rabago F., de Santago E., Moncada J.I., Universidad Autonoma de San Luis Potosi, MX

In this work we presente the results obtained with a electronic circuit to control temperature, water, humidity and fertilizer of plants in a greenhouse. Different sensors were located in the greenhouse and electrovalves were activated [...]

Exploring the IR-limit of the Triplet-Triplet Annihilation Upconversion: Tetraaryltetraanthra[2,3]porphyrin – family

Filatov M., Ilieva I., Landfester K., Baluschev S., MPIP, DE

The main advantage of the techniques, using photon conversion is that conversion processes and devices can be considered and optimized independently, without affecting the particular physical properties of the operating photovoltaic material or device architectures. [...]
