The effects of MoO3thin buffer layer on charge carrier injection and extraction in inverted configuration ITO/ZnO/MEH-PPV(poly(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene))/MoO3(0,5 nm)/Ag hybrid solar cells are investigated by capacitance–voltage measurement under dark and light illumination conditions.The ef…
We designed a high-efficiency dispersive mir- ror based on multi-layer dielectric meta-surfaces. By replacing the secondary mirror of a dome solar concen- trator with this dispersive mirror, the solar concentrator can be converted into a spectrum-splitting photovoltaic system with higher energy harvesting efficiency a…
The distributions of energy depositions of electrons in semi-infinite bulk protein and the radial dose distributions of point-isotropic mono-energetic electron sources (i.e., the so-called dose point kernel (DPK)) in protein have been systematically calculated in the energy range below 20 keV, based on Monte Carlo met…
Molecular dynamic simulations have been performed to study the solid solution mechanism of Mg100-xREx (RE = Gd, Dy, Y, x = 0.5, 1, 2, 3, 4 at.%). The obtained results reveal that the additions of Gd, Dy and Y increase the lattice constants of Mg-RE alloys. Also the axis ratio c/a remains unchanged with increase in tem…
Reduced graphene oxide/Mn3O4(rGO/Mn3O4) nanocomposites were prepared from MnSO4and GO produced by a modified Hummers method. The GO was deoxygenated by heat treatment,and MnO2generated by hydrolysis of MnSO4was simultaneously reduced to Mn3O4. The Mn3O4content in the composites could be tailored by the volume of super…
Rencently, covalent functionalization carbon nanotubes have been received special attention because of the expansive application prospect in the areas of nanoscience and nanotechnology. Moreover, covalent functionalization of carbon nanotubes can readily deal with fundamental issues of purification, solubilization, an…
