Photocurrent decay from the steady-state in thin film hydrogenated amorphous silicon: Numerical simulation analysis of experimental results
(Elsevier Science SA, 2020-10)
Starting from the multiple trapping rate equations that define the non-equilibrium concentrations of electrons and holes in extended states, the experiment of photocurrent decay from the steady-state is examined. A system ...
UV-photocurrent response of zinc oxide based devices: Application to ZnO/PEDOT:PSS hydrid Schottky diodes
(2021-01-01)
The UV photocurrent response of thin films of wide bandgap semiconductors such as zinc oxide (ZnO) can be applied to a great number of electronic devices aiming applications in environmental sensing or UV-detection. ...

Charge Transport and Gradient Doping in Nanostructured Polypyrrole Films for Applications in Photocurrent Generation
(2020-01-01)
The investigation of the charge-transport mechanism across disordered conducting and semiconducting materials is of relevance, considering the applications in modern organic and hybrid electronics. The transition from bulk ...
Investigation of charge recombination lifetime in gamma-WO3 films modified with Ag-0 and Pt-0 nanoparticles and its influence on photocurrent density
(Springer, 2018-10-01)
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 ...
Origin of photoresponse in black phosphorus phototransistors
(Amer Physical Soc, 2014-08-29)
We study the origin of a photocurrent generated in doped multilayer black phosphorus (BP) phototransistors, and find that it is dominated by thermally driven thermoelectric and bolometric processes. The experimentally ...
ZnO nanowire sensitization with Ru polypyridyl complexes: charge-transfer probed by spectral and relaxation photocurrent measurements
(IOP Publishing, 2018-07-11)
Dye-sensitized ZnO nanowire (NW) electrodes were fabricated using Ru polypyridyl complexes that use nitrile instead of carboxylic group as anchoring unit to the NW surfaces. The complexes formula is [Ru(bpy)3−x(Mebpy-CN)x]2+ ...
Up-conversion mechanisms in Er3+-doped fluoroindate glasses under 1550 nm excitation for enhancing photocurrent of crystalline silicon solar cell
(2018-08-01)
In this work, Er3+-containing fluoroindate glasses were synthesized by the conventional melt-quenching method varying Er3+ content from 0.1 to 7 mol%. The series of fluoroindate glass were investigated according to their ...
