Carbon-doped nanostructured CuMo-based photocatalysts were prepared by solvothermal synthesis. Two thermal treatments—oxidative and inert atmosphere—were used for the synthesis of catalysts, influence spherical carbon structures upon crystalline phases on photocatalytic activity stability was studied. XRD showed catalysts are composed a mixture copper (Cu, Cu2O, CuO) molybdenum (MoO2 MoO3) phas...

We present a theoretical model of composite excitonic states in doped semiconductors. Many-body interactions between photoexcited electron-hole pair and the electron gas are integrated into computationally tractable few-body problem, solved by variational method. focus on electron-doped monolayer (ML)-$\mathrm{Mo}{\mathrm{Se}}_{2}$ ML-$\mathrm{W}{\mathrm{Se}}_{2}$ due to contrasting character t...

SnSe2, a layered posttransition metal chalcogenide, has attracted attention as high-efficiency thermoelectric material owing to the intrinsic low thermal conductivity. Herein, series of Sn S e 1 − x T<...

The rear interface of kesterite absorbers with Mo back contact represents one the possible sources nonradiative voltage losses (ΔVoc,nrad) because reported decomposition reactions, an uncontrolled growth MoSe2, or a nonoptimal electrical high recombination. Several intermediate layers (IL), such as MoO3, TiN, and ZnO, have been tested to mitigate these issues, efficiency improvements reported. ...

The electrocatalytic properties of metal oxides (MO = Fe3O4, ZnO) nanoparticles doped phthalocyanine (Pc) and functionalized MWCNTs, decorated on glassy carbon electrode (GCE) was investigated. Successful synthesis of the metal oxide nanoparticles and the MO/Pc/MWCNT composite were confirmed using UV-Vis, EDX, XRD and TEM techniques. Successful modification of GCE with the MO and their composit...

The cell-to-module efficiency gap in Cu(In,Ga)Se2 (CIGS) monolithically integrated solar modules is enhanced by contact resistance between the Al-doped ZnO (AZO) and Mo back contact layers, the P2 contact, which connects adjacent cells. The present work evaluated the P2 contact resistance, in addition to the TCO resistance, using an embedded transmission line structure in a commercial-grade mod...

Abstract A series of supported Ni-Mo catalysts were synthesised through a deposition-co-precipitation method (DcP) and investigated in combined steam dry reforming. The prepared by Yttria-Stabilised Zirconia (YSZ), Gadolinium-Doped Ceria (GDC) Stabilised (CSZ) with improved carbon tolerance have the potential to be used as anodes Solid Oxide Fuel Cells (SOFC). These will applied anode supportin...

The chemical reduction progression behaviour of transition metals (Mo, Zr, W, Ce, and Co) doped on NiO was studied using temperature programmed (TPR) analysis. A wet impregnation method applied to synthesise the series catalysts. progress catalysts attained by a reductant gas at concentration 40% v/v CO/N2. X-ray diffraction (XRD) employed determine composition reduced phases. Undoped 384℃ obta...
