Rectification properties and pH-dependent selectivity of meningococcal class 1 porin
(2008)
We studied the current rectification properties and selectivity of class 1 porin (PorA) from Neisseria meningitidis (strain H44/76 A3A4) reconstituted in planar lipid membranes varying salt concentrations and pH. PorA ...
Assessing possibilities and limits for solar cells
(Wiley, 2011-05-05)
What are the solar cell efficiencies that we can strive towards? We show here that several simple criteria, based on cell and module performance data, serve to evaluate and compare all types of today's solar cells. Analyzing ...
Energy transfer versus charge separation in hybrid systems of semiconductor quantum dots and Ru-dyes as potential co-sensitizers of TiO2-based solar cells.
(© 2011 American Institute of Physics, 2011-07)
Hybrid structures of colloidal quantum dots (QDs) with Ru-dyes have been studied as candidates for panchromatic sensitizers for TiO2-based solar cells. Steady-state and time resolved photoluminescence spectroscopy and ...
On voltage, photovoltage, and photocurrent in bulk heterojunction organic solar cells
(American Chemical Society, 2011-07)
The interpretation of voltage, photovoltage, and photocurrent in polymer/fullerene bulk heterojunction (BHJ) solar cells is discussed in terms of fundamental device models and results of capacitance spectroscopy. First we ...
Linearity, saturation and blocking in a large multiionic channel: divalent cation modulation of the OmpF porin conductance
(Elsevier, 2011-01)
Measurement of unitary conductance is a fundamental step in the characterization of a protein ion channelpermeabilizing a membrane. We study here the effect of salts of divalent cations on the OmpF channelconductance ...
Temperature dependence of open-circuit voltage and recombination processes in polymer–fullerene based solar cells
(Elsevier, 2011)
In this article, we have studied the temperature and illumination dependence of open-circuitvoltage (VOC) in polymer–fullerenebasedsolarcells. It has been observed that VOC at higher illumination intensities gets converged ...
Operating modes of sandwiched light-emitting electrochemical cells
(Wiley, 2011-03-14)
Light-emitting electrochemical cells (LECs) are promising lighting devices in which the redistribution of ionic charges allows for double electronic carrier injection from air-stable electrodes. Uncertainties about the ...
Relaxation dynamics of poly(vinylidene fluoride) studied by dynamical mechanical measurements and dielectric spectroscopy
(EDP SciencesSocietà Italiana di FisicaSpringer, 2012)
The aim of this study is to analyze the mobility of polymer chains in semicrystalline poly(vinylidene fluoride) (PVDF). PVDF crystallizes from the melt in the α crystalline phase. The transformation
from the α phase to the ...
