Enhancing DSSC conversion efficiency by ozone-treated TiO 2 photoanode and optimum CNT/PDDA counter electrode

, 2020
The conversion efficiency of dye-sensitized solar cells (DSSCs) depends on the performance of the photoanode and the counter electrode. In this paper, UV-ozone treatment has been applied to the photoanode to clean and increase the hydrophilicity of the ...

Long-term durability of metastable β-Fe2O3 photoanodes in highly corrosive seawater

Nature Communications, 2023
Durability is one prerequisite for material application. Photoelectrochemical decomposition of seawater is a promising approach to produce clean hydrogen by using solar energy, but it always faces the problem of serious Cl− corrosion.

Luminescence Amplification at BiVO₄ Photoanodes by Photoinduced Electrochemiluminescence [PDF]

Angewandte Chemie International Edition, 2020
AbstractPhotoinduced electrochemiluminescence (PECL) combines semiconductor (SC) photoelectrochemistry with electrochemiluminescence (ECL). In PECL, the incident light is converted into a different wavelength by an electrochemical reaction at a SC photoelectrode and allows triggering of ECL at low potentials. This concept has been employed to design up‐

Amorphous ferric oxide as a hole-extraction and transfer layer on nanoporous bismuth vanadate photoanode for water oxidation

, 2017
An amorphous ferric oxide layer was prepared on a bismuth vanadate photoanode. This resulted in improved charge carrier separation and surface catalytic performance compared with the photoanode without the oxide layer. The photocurrent of the oxide-layer-

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
