Gating That Suppresses Charge Recombination-The Role of Mono-N-Arylated Diketopyrrolopyrrole
(American Chemical Society, 2016-10)
Suppressing the charge recombination (CR) that follows an efficient charge separation (CS) is of key importance for energy, electronics, and photonics applications. We focus on the role of dynamic gating for impeding CR ...
DIRECT SPECTROSCOPIC EVIDENCE FOR CONSTITUENT HETEROATOMS ENHANCING CHARGE RECOMBINATION AT A TIO2-RUTHENIUM DYE INTERFACE
(AMERICAN CHEMICAL SOCIETY, 2014)
Impedance spectroscopy study of solid-state dye-sensitized solar cells with varying Spiro-OMeTAD concentration
This work reports on the changes of performance of solid-state cells dye-sensitized solar cells with the variation of concentration of spiro-OMeTAD between 5% and 25% in the fabrication of the cell. Variations of charge ...

Charge transfer mechanism of WO3/TiO2 heterostructure for photoelectrochemical water splitting
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. ...
Investigation of charge recombination lifetime in gamma-WO3 films modified with Ag-0 and Pt-0 nanoparticles and its influence on photocurrent density
In this communication, we report the growth of pure gamma-phase tungsten oxide (gamma-WO3) films on a conducting substrate (fluorine-doped tin oxide), followed by heat treatment at 500 A degrees C for 2 h, and finally ...
Optical detection of charge redistribution in a delta modulation-doped GaAs-AlxGa1-xAs heterojunction
