A Review on Oxygen-Deficient Titanium Oxide for

Pulsed laser irradiation is a simple process for producing oxygen-deficient TiO 2; however, this is more suitable for treating films because the radiation response mainly happens in the surface layer. Similarly, oxygen

Effect of oxygen deficiency on the excited state kinetics

For highly oxygen-deficient films, photoelectron spectroscopy shows an over 2 eV broad distribution of oxygen vacancy states within the bandgap which gives rise to extended visible light absorption. We examine the nature of this distribution

Creation of oxygen vacancies to activate WO

In this work, oxygen vacancies were created to activate tungsten trioxide (WO 3) as a highly efficient counter electrode (CE) in dye-sensitized solar cells (DSSCs). The levels of oxygen vacancies (OVs) in WO 3 were finely formed and tuned

6 FAQs about [Oxygen-deficient solar power generation is low]

How does oxygen-deficient black zirconia (ZrO 2x) affect solar light absorption?

In conclusions, oxygen-deficient black zirconia (ZrO 2−x) was prepared via the magnesiothermic reduction in H 2 /Ar atmosphere, which resulted in a drastic increment in solar light absorption and band gap decrement (to 1.52 from 5.09 eV for white ZrO 2 ).

Is energy loss a problem in organic solar cells?

Provided by the Springer Nature SharedIt content-sharing initiative Energy loss within organic solar cells (OSCs) is undesirable as it reduces cell efficiency1–4.

How are oxygen defects created?

Besides gaseous hydrogen reduction, oxygen defects were also created via solid-state reduction of (Sr 1 − x Ba x)FeO 2 perovskite using solid reagents that can thermally release hydrogen (CaH 2, NaH) and wet-chemical reduction with H 2 O 2 aqueous solution on La 0.8 Sr 0.2 CoO 3 − δ (LSC) .

Does low formation energy cause oxygen vacancies in perovskite oxides?

Typically, low formation energy results in a higher degree of oxygen defects. Sr and Ca are the most favorable and commonly used alkaline-earth metals to create oxygen vacancies in ABO 3 -type perovskite oxides [3, 70].

Does oxygen deficiency affect photo-generated charge carrier recombination?

For our oxygen-deficient WO 3–x /Zn 0.3 Cd 0.7 S Z-scheme system, the photo-generated holes tend to be present in the VB WO 3–x, while the electrons in the conduction band of WO 3–x combine with the holes of Zn 0.3 Cd 0.7 S through the interface contact. As a result, the photo-generated charge carrier recombination can be significantly decreased.

Why does a reduced material always have surface oxygen vacancies?

A reduced material with oxygen vacancies tends to always have surface oxygen vacancies since reduction initially attacks surface lattice oxygen, and consequently through the deconvolution of the O 1s spectra of a reduced material, the determination of vacant sites can be inferred.
