During the last decade, transition metal oxides have been actively investigated as holeand electron-selective materials in organic electronics due to their low-cost processing. In this study, four transition metal oxides (V2O5, MoO3, WO3, and ReO3) with high work functions (>5 eV) were thermally evaporated as front p-type contacts in planar n-type crystalline silicon heterojunction solar cells....

The color changes in chemo- and photochromic MoO3 used in sensors and in organic photovoltaic (OPV) cells can be traced back to intercalated hydrogen atoms stemming either from gaseous hydrogen dissociated at catalytic surfaces or from photocatalytically split water. In applications, the reversibility of the process is of utmost importance, and deterioration of the layer functionality due to si...

We study electron and hole injection in MoO3 charge generation layers CGLs commonly used for establishing balanced injection in multilayer stacked organic light-emitting diodes SOLEDs . A compound CGL consisting of 100-Å-thick MoO3 and Li-doped 4,7-diphenyl-1,10-phenanthroline in a 1:1 molar ratio is demonstrated to have a high electron generation efficiency. Charge injection from the compound ...

MoO2 hollow microspheres with tunable inner space have been synthesized through a hydrothermal process using MoO3 microbelts instead of bulk MoO3 as the precursor. It is found that the reactant morphology has a great impact on the product morphology and the inner space can be tuned by changing the amount of NaOH aqueous solution. An interesting evolutional process from MoO3 microbelts through a...

Several parameters of the fabrication process of inverted polymer bulk heterojunction solar cells based on titanium oxide as an electron selective layer and molybdenum oxide as a hole selective layer were tested in order to achieve efficient organic photovoltaic solar cells. Thermal annealing treatment is a common process to achieve optimum morphology, but it proved to be damageable for the per...

The nature of MoO3 and MoO3/Al2O3 ultrathin films supported on Mo~110! and their interactions with CH3OH have been investigated using surface science techniques. The ultrathin (,50 Å) films were characterized by Auger electron spectroscopy, low energy electron diffraction, and high resolution electron energy loss spectroscopy ~HREELS! of their phonon vibrational modes and electronic transition ...

The supplementary data have included a full range of TEM pictures of the post-run samples, including 400 oC calcinated MoO3/H-ZSM-5 samples (coked) and the parent H-ZSM-5 (coked), showing the distribution of Mo clusters on the zeolite crystallite external surface, and the observed coke deposition upon the spreading of the Mo species. The Figures S1-S9 are the complementary of the Fig. 8 in the ...

Efficient and simple syntheses of [(n-C4H9)4N]4[α-Mo8O26] (I) and [(n-C4H9)4N]2[Mo2O7] (II) from MoO3 and aqueous [(n-C4H9)4N]OH are described. The yield is 72% for I and 73% for II.

We theoretically propose and study in-plane anisotropic acoustic phonon polaritons (APhPs) based on a layered structure consisting of monolayer (or few layers) {\alpha}-phase molybdenum trioxide ({\alpha}-MoO3) sandwiched between two metal layers. find that the APhPs in proposed structures are canalization (highly directional) electromagnetic mode propagating along with layers at same time exhi...
