Impedance Spectroscopy Measurements in Perovskite Solar Cells: Device Stability and Noise Reduction
(American Chemical Society, 2018)
Scaling Behavior of Ionic Transport in Membrane Nanochannels
(American Chemical Society, 2018)
Ionic conductance in membrane channels
exhibits a power-law dependence on electrolyte concentration
(G ∼ c
α
). The many scaling exponents, α, reported in the
literature usually require detailed interpretations ...
Mutation-induced changes of transmembrane pore size revealed by combined ion-channel conductance and single vesicle permeabilization analyses
(Elsevier, 2018-05)
Permeabilization of the Endoplasmic Reticulum (ER) is instrumental in the progression of host-cell infection by many viral pathogens. We have described that permeabilization of ER model membranes by the pore-forming domain ...
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. ...
Unravelling the role of vacancies in lead halide perovskite through electrical switching of photoluminescence
(Nature Research, 2018)
We address the behavior in which a bias voltage can be used to switch on and off the
photoluminescence of a planar film of methylammonium lead triiodide perovskite (MAPbI3)
semiconductor with lateral symmetric electrodes. ...
Bioelectrical Signals and Ion Channels in the Modeling of Multicellular Patterns and Cancer Biophysics
(Nature Publishing Group, 2016)
Bioelectrical signals and ion channels are central to spatial patterns in cell ensembles, a problem
of fundamental interest in positional information and cancer processes. We propose a model for
electrically connected ...

Physical aspects of ferroelectric semiconductors for photovoltaic solar energy conversion
(Elsevier, 2016-10)
Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on efficient light absorption, charge separation of electron–hole pair carriers or excitons, and fast transport and charge extraction ...
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 ...
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 ...
