Perimeter leakage current in polymer light emitting diodes
(Elsevier, 2009)
Observation of leakage current paths through the device perimeter in standard poly(phenylene vinylene)-based light-emitting devices is reported. Perimeter leakage currents govern the diode performance in reverse and low ...
Room temperature stable ClPrNTf2 ionic liquid utilizing for chemical sensor development
(Elsevier, 2016-06)
A stable ionic liquid was prepared at room-temperature using the metathesis reaction, which was consummated by the reaction of l-Phenylalanine ethyl ester hydrochloride (chlorpromazine hydrochloride) with lithium-bis(tri ...
Interpretation of Diffusion and Recombination in Nanostructured and Energy-Disordered Materials by Stochastic Quasiequilibrium Simulation
(American Chemical Society, 2013)
The main electronic feature of many nanocrystalline semiconductors and I organic materials is the presence of a distribution of localized states in the system with a broad energy dispersion. Carrier transport and recombination ...
Understanding the Improvement in the Stability of a Self-Assembled Multiple-Quantum Well Perovskite Light-Emitting Diode
(American Chemical Society, 2020-11-07)
We fabricate two-dimensional Ruddlesden–Popper layered perovskite films by introducing 1-naphthylmethylamine iodide into the precursor, which forms a self-assembled multiple-quantum well (MQW) structure. Enabling outstanding ...
Oxygen transport through methacrylate-based hydrogels with potential biological capability
(Elsevier, 1996)
The permeability to oxygen of hydrogels prepared from copolymers of 2-hydroxymethyl methacrylate and p-methacryloxyl-oxyacetanilide have been studied by using an oxygen electrode in combination with a permeometer. The ...
Glassy dynamics predicted by mutual role of free and activation volumes
(Royal Society of Chemistry, 2019)
Broadband Dielectric Spectroscopy (BDS) at elevated pressures and Positron Annihilation LifetimeSpectroscopy (PALS) are employed to elucidate the importance of the ratio of activation and freevolumes during vitrification. ...
Origin of high open-circuit voltage in solid state dye-sensitized solar cells employing polymer electrolyte
(Elsevier, 2016-10)
Herein, the energy level alignment and electron recombination kinetics in solid state dye-sensitized solar cells (DSCs) employing a solid polymer electrolyte (SPE) have been quantitatively characterized. In order to determine ...
Toward Efficient Carbon Nitride Photoelectrochemical Cells: Understanding Charge Transfer Processes
(Wiley, 2016-06)
Hole extraction is the key! Charge recombination, electron injection and hole extraction rates between C3N4, TiO2, and several electrolytes in a photoelectrode configuration are studied. It is found that the TiO2/C3N4 ...
Relaxation of Photogenerated Carriers in P3HT:PCBM Organic Blends
(Wiley, 2009)
Relaxing in the sunlight. Long time-transient decays of photogenerated carriers in P3HT:PCBM blends for organic solar cells are interpreted in terms of the relaxation of hole carriers in a broad density of states.
The ...
Electron Transport Layer-Free Solar Cells Based on Perovskite? Fullerene Blend Films with Enhanced Performance and Stability
(Wiley, 2016-08)
The solution processing of pinhole-free methylammonium lead triiodide perovskite–C70 fullerene (MAPbI3:C70) blend films on fluorine-doped tin oxide (FTO)-coated glass substrates is presented. Based on this approach, a ...
