Charge transfer mechanism of WO3/TiO2 heterostructure for photoelectrochemical water splitting
(2017-04-15)
The present study shows how electronic parameters (e.g. band gap energy, band edge positions) on semiconductors affect photoelectrochemical activity in simulated solar light using WO3, TiO2 and WO3/TiO2 as model systems. ...
ESR observations of paramagnetic centers in intrinsic hydrogenated microcrystalline silicon

Nanocompósitos de óxidos de ferro e pontos de carbono e suas aplicações em processos oxidativos avançados
(Universidade Federal de Minas GeraisUFMG, 2019-02-28)
Photocatalysis reaction are promoted by the UV/Vis irradiation and catalyzed by semiconductors that undergo excitation of an electron from the valence band to the conduction band. The pair of electron (excited in the ...
Dark Current Voltage Characteristics of Micromorph Silicon Tandem Cells
(American Institute Of Physics, 2009-05-02)
The transport mechanisms controlling the forward dark current-voltage characteristic of the silicon micromorph tandem solar cell were investigated with numerical modeling techniques. The dark current-voltage characteristics ...
Electron scattering and effects of sources of light on photoconductivity of SnO2 coatings prepared by sol-gel
(Elsevier B.V., 1999-05-01)
Electro-optical properties of sol-gel derived 2 mol% antimony or niobium doped tin dioxide films have been measured. The electron density has been calculated considering all the relevant scattering mechanisms and experimental ...

The origin of photoluminescence in amorphous lead titanate
(Kluwer Academic Publ, 2003-03-15)
We discuss the nature of visible photoluminescence at room temperature in amorphous lead titanate in the light of the results of recent experimental and theoretical calculations. Experimental results obtained by XANES and ...

Electro-optical properties of Er-doped SnO2 thin films
(Elsevier B.V., 2004-01-01)
Photoconductivity of SnO2 sol-gel films is excited, at low temperature, by using a 266 nm line-fourth harmonic-of a Nd:YAG laser. This line has above bandgap energy and promotes generation of electron-hole pairs, which ...
