Ion channel activity of the CSFV p7 viroporin in surrogates of the ER lipid bilayer
(Elsevier, 2016-01)
Viroporins comprise a family of non-structural proteins that play significant and diverse roles during the replication cycle of many animal viruses. Consequently, they have become promising targets for inhibitory drug and ...
Selectivity of Protein Ion Channels and the Role of Buried Charges. Analytical Solutions, Numerical Calculations, and MD Simulations
(American Chemical Society, 2015-06)
The preference of large protein ion channels for cations or anions is mainly determined by the electrostatic interactions of mobile ions with charged residues of the protein. Here we discuss the widely spread paradigm that ...
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 ...
Amorphous TiO2 Buffer Layer Boosts Efficiency of Quantum Dot Sensitized Solar Cells to over 9%
(American Chemical Society, 2015)
Charge recombination at an electrode/electrolyte interface is the main factor to limit the power conversion efficiency (PCE) of quantum dot sensitized solar cells (QDSCs). Herein, we present a novel and facile strategy ...
Impedance spectroscopic analysis of high-performance dye sensitized solar cells based on nano-clay electrolytes
(Elsevier, 2016)
In this work we present quasi-solid state dye-sensitized solar cells obtained employing artificial hydrotalcite nano-clay as electrolyte additive, with a greatly improved photo-energy conversion efficiency of up to 10.9% ...
Capacitive dark currents, hysteresis, and electrode polarization in lead halide perovskite solar cells
(American Chemical Society, 2015-04)
Despite spectacular advances in conversion efficiency of perovskite solar cell many aspects of its operating modes are still poorly understood. Capacitance constitutes a key parameter to explore which mechanisms control ...
Co3O4 based all-oxide PV: a numerical simulation analyzed combinatorial material science study
(American Chemical Society, 2016)
Here we investigate the impact of four different metal back contacts on the photovoltaic (PV) performance of Co3O4 thin film all-oxide photovoltaic cells. A combinatorial TiO2|Co3O4 heterojunction thin film device library ...
Boosting Power Conversion Efficiencies of Quantum-Dot-Sensitized Solar Cells Beyond 8% by Recombination Control
(American Chemical Society, 2015)
At present, quantum-dot-sensitized solar cells (QDSCs) still exhibit moderate power conversion efficiency (with record efficiency of 6–7%), limited primarily by charge recombination. Therefore, suppressing recombination ...
Energy Diagram of Semiconductor/Electrolyte Junctions
(American Chemical Society, 2013-12)
In electrochemistry and photoelectrochemistry, it is most common to refer the voltage to a reference electrode (RE) or in a two-electrode cell with respect to a counterelectrode (CE).(1, 2) However, in a semiconductor film ...
All solution processed low turn-on voltage near infrared LEDs based on core–shell PbS–CdS quantum dots with inverted device structure
(Royal Society of Chemistry, 2014)
Colloidal semiconductor quantum dots (QDs) are extraordinarily appealing for the development of light emitting devices (LEDs) due to tunable and pure color emission, brightness and solution processability. This last advantage ...
