Determination of charge carrier mobility of hole transporting polytriarylamine-based diodes
(Elsevier, 2010)
Hole transport properties of three different side chain poly(triarylamines) have been determined by means of the analysis of steady-state current-voltage characteristics using co-planar diode structures. The interpretation ...
Effect of annealing on the permeation characteristics of gases of coextruded LLDPE films
(Elsevier, 1996)
The temperature dependence of both the permeability and diffusion coefficients of carbon dioxide, oxygen and nitrogen in annealed LLDPE films are studied. It is found that the values of the permeability coefficient through ...
Theory of the impedance of charge transfer via surface states in dye-sensitized solar cells
(Elsevier, 2010)
The dynamics of trapping coupled with charge transfer is analysed in the frequency domain for a model of the dye-sensitized solar cell. We solve the steady state occupations of the surface state and the resulting recombination ...
Co-adsorbing effect of bile acids containing bulky amide groups at 3β-position on the photovoltaic performance in dye-sensitized solar cells
(Elsevier, 2019)
Co-adsorbing molecules attain certain control in the surrounding of the dyes leading to enhanced efficiencies mainly by affecting the recombination of the photogenerated electrons and aggregation of dyes. Bile acids such ...
Excitons diffusion and singlet-triplet occupation at high Bose-Einstein chemical potential
(Elsevier, 2008)
The paper investigates the bosonic aspects of exciton statistics in non-equilibrium situations. A kinetic model is formulated treating the excitons in different states as chemical species, using a master equation consistent ...
In Situ Spectroscopic Ellipsometry for Thermochromic CsPbI3 Phase Evolution Portfolio
(American Chemical Society, 2020-04-09)
Thermochromism is a color change phenomenon for a compound when it undergoes a heating/cooling process. The observation of this phenomenon mostly relies on the naked eye, rather than an exact optical technique, which retards ...
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 ...
High carrier density and capacitance in TiO2 Nanotube arrays induced by electrochemical doping
(American Chemical Society, 2008)
The paper describes the electronic charging and conducting properties of vertically oriented TiO2 nanotube arrays formed by anodization of Ti foil samples. The resulting films, composed of vertically oriented nanotubes ...
Characterization of nanostructured hybrid and organic solar cells by impedance spectroscopy
(RSC Publishing, 2011-04-06)
We review the application of impedance spectroscopy in dye-sensitized solar cells, quantum dot-sensitized solar cells and organic bulk heterojunction solar cells. We emphasize the interpretation of the impedance parameters ...
Ionic conductivity and diffusion coefficients of lithium salt polymer electrolytes measured with dielectric spectroscopy
(Elsevier, 2011)
Ionic conductivity, diffusion coefficients, mobility and ionic concentration for lithium salts dissolved in polymer electrolytes are determined by the modeling of the dielectric loss and spectra. Cation and anion diffusion ...
