Dielectric relaxation dynamics in poly(vinylidene fluoride)/Pb(Zr0⋅53Ti0.47) O3 composites
(Elsevier, 2020)
Polymer-ceramic composites based on poly(vinylidene fluoride) and ceramic particles of the inorganic piezoelectric material Pb(Zr0·53Ti0.47)O3 were prepared with different particle concentrations and size by solution casting ...
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 ...
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 ...
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 ...
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 ...
Synthesis and characterization of organic agar-based membranes for microbial fuel cells
(Elsevier, 2019-09-30)

Theory of Impedance Spectroscopy of Ambipolar Solar Cells with Trap-Mediated Recombination
(American Chemical Society, 2014-01)
The analysis of recombination in solar cells suggests in many cases the presence of trap-mediated recombination in the absorber. We present a theory of the recombination of electrons and holes, the Shockley–Read–Hall model, ...
Theory of Impedance and Capacitance Spectroscopy of Solar Cells with Dielectric Relaxation, Drift-Diffusion Transport, and Recombination
(American Chemical Society, 2014-07)
Semiconductor photovoltaic devices currently investigated, such as hybrid organic–inorganic lead halide perovskite based solar cells, have shown a high dielectric polarization combined with ambipolar carrier transport. In ...
A perspective on the production of dye-sensitized solar modules
(Royal Society of Chemistry, 2014)
Dye-sensitized solar cells (DSCs) are well researched globally due to their potential as low-cost photovoltaic (PV) devices especially suited for building and automobile integrated PV (BIPV, AIPV) and portable or indoor ...
