Trap-limited mobility in space-charge limited current in organic layers
(Elsevier, 2009)
Space-charge limited current transport in organic devices, relevant to the operation of a range of organic optoelectronic devices, is analyzed in the frequency domain. The classical multiple trapping picture with one ...
Synthesis and characterization of organic agar-based membranes for microbial fuel cells
(Elsevier, 2019-09-30)
The goal of this work was the synthesis and characterization of agar membranes for microbial fuel cells applications. Three sets of membranes were synthesized. For a first set of membranes (2, 4, 6, and 8 wt% agar ...
Electron-Transfer Kinetics through Interfaces between Electron-Transport and Ion-Transport Layers in Solid-State Dye-Sensitized Solar Cells Utilizing Solid Polymer Electrolyte
(American Chemical Society, 2016)
The origin of the differences between the performance parameters found for dye-sensitized solar cells (DSCs) using liquid and poly(ethylene oxide)-based solid polymer electrolytes has been investigated. Limitations associated ...
Charge carrier mobility and lifetime of organic bulk heterojunctions analyzed by impedance spectroscopy
(Elsevier, 2008)
Charge carrier diffusion and recombination in an absorber blend of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C<sub>61</sub>-butyric acid methyl ester (PCBM) with indium tin oxide (ITO) and aluminium contacts have been ...
Efficient blue emitting organic light emitting diodes based on fluorescent solution processable cyclic phosphazenes
(Elsevier, 2008)
Solution processable blue fluorescent dendrimers based on cyclic phosphazene (CP) cores incorporating amino-pyrene moieties have been prepared and used as emissive layers in organic light emitting diodes (OLEDs). These ...
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 ...
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 ...
Influence of cysteine adsorption on the performance of CdSe quantum dots sensitized solar cells
(Elsevier, 2010)
The surface of mesoporous TiO<sub>2</sub> electrodes has been functionalized with cysteine using different solutions for the subsequent attachment of colloidal CdSe QDs solved in toluene. The adsorption behavior of both ...
