Sentence examples for back electron transfer from from inspiring English sources

An upward shift in the Fermi level has been observed, perhaps responsible for the improved performance along with the possibility of preventing the back electron transfer from TiO2.

PEDOT polymer was electrochemically coated over a quantum dot-sensitized semiconductor and efficiently suppressed the back electron transfer from the semiconductor, thereby improving the photocurrent as compared to the uncoated control (13 vs 6 mA/cm2, respectively).

It can be concluded that further improvements in ZnO-based DSSCs are possible by: (i) avoiding the formation of Zn2+-dye aggregates in the mesoporous structure; (ii) preventing back electron transfer from ZnO to the electron acceptor in the electrolyte solution.

The energy barrier will be favorable to suppress the back electron transfer from FTO to electrolytes.

The back electron transfer from the FTO front electrode to the perovskite by the ~200-nm penetration may cause the recombination path, as seen in SEM image of Fig. 2e [45].

Typically, the coverage of mesoporous TiO2 by QDs is much less than a full monolayer [6, 7], which leads to insufficient light harvesting and back electron transfer from exposed TiO2 to electrolyte.

The analysis results reveals that the Al doped TiO2 coating can reduce the oxygen vacancy-Ti3+ concentrations in the photoanodes significantly, which is beneficial to suppress the back electron transfer process from TiO2 to electrolyte.

The specific molecular design of porphyrin sensitizers significantly retards the rate of interfacial back-electron transfer from the conduction band of the nanocrystalline titanium dioxide photoanode to the oxidized cobalt mediator, leading to the attainment of extraordinarily high photovoltage of about 1 volt [141].

Though the dye containing bithiophene unit exhibited comparatively low Voc due to low electron life time and facile back electron transfer, showed high power conversion efficiency arising from the good light-harvesting capability attributable to the intense absorption peak in the visible region and enhanced interfacial electron transfer rate.

The experimental data is fitted and rate constants for electron transfer from the nanoparticle to the substrate, hole capture, recombination and back electron transfer are determined.

The compact TiO2 hole-blocking layer more effectively inhibits the direct contact between the FTO and the perovskite (preventing the back electron transfer), which is predicted as the origin of charge recombination from the one-diode model.
