Recombination in Quantum Dot Sensitized Solar Cells
(American Chemical Society, 2009-11)
Quantum dot sensitized solar cells (QDSCs) have attracted significant attention as promising third-generation photovoltaic devices. In the form of quantum dots (QDs), the semiconductor sensitizers have very useful and often ...
On the methods of calculation of the charge collection efficiency of dye sensitized solar cells
(Royal Society of Chemistry, 2013)
The charge collection efficiency is one of the most critical parameters of photovoltaic devices. In this paper we provide the analysis and comparison between several approaches for the calculation of the collection efficiency ...
Ion selectivity of a biological channel at high concentration ratio: insights on small ion diffusion and binding
(American Chemical Society, 2009)
The ionic selectivity of the bacterial porin OmpF has been investigated in several chloride salts of alkali metal cations under a wide range of concentration ratios. We report a novel way of studying the several factors ...
Surface Passivation of Nanoporous TiO2 via Atomic Layer Deposition of ZrO2 for Solid-State Dye-Sensitized Solar Cell Applications
(American Chemical Society, 2009)
We report here the utilization of atomic layer deposition to passivate surface trap states in mesoporous TiO2 nanoparticles for solid-state dye-sensitized solar cells based on 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylami ...
A star-shaped sensitizer based on thienylenevinylene for dye-sensitized solar cells
(Elsevier, 2013-01)
A novel star-shaped dye based on highly conjugated oligothienylenevinylene (nTV) bearing pendant solubilizing hexyl chains and end-capped with three tetramethylammonium cyanoacetates as anchoring groups has been synthetized. ...
Segmental dynamics in poly(ε-caprolactone)/poly(L-lactide) copolymer networks
(Wiley, 2009)
Poly(ε-caprolactone) (PCL) and poly(lactic acid) (PLA) networks were prepared from macromonomer diols functionalized with methacrylic anhydride, which allows one to get self-crosslinkable polymers. Besides, both macromonomers ...
CdSe quantum dot-sensitized TiO2 electrodes: effect of quantum dot coverage and mode of attachment
(American Chemical Society, 2009)
We have investigated the sensitization of nanoporous titanium dioxide by previously synthesized CdSe quantum dots (QDs) protected with trioctylphosphine. Covering the nanoporous TiO2 films with QDs has been achieved using ...
Electron Lifetime in Dye-Sensitized Solar Cells: Theory and Interpretation of Measurements
(American Chemical Society, 2009)
The electron lifetime τn in dye-sensitized solar cells (DSC) is a central quantity to determine the recombination dynamics in the solar cell. It can be measured by several methods: impedance spectroscopy, IMVS, stepped ...
Chemical Effects of Tin Oxide Nanoparticles in Polymer Electrolytes-Based Dye-Sensitized Solar Cells
(American Chemical Society, 2014-02)
The effects on the photovoltaic performance of the incorporation of SnO2 nanoparticles into the polymer of a solid-state dye-sensitized solar cell (DSC) based on the poly(ethylene oxide)/poly(ethylene glycol) dimethyl ether ...
Entropy–enthalpy compensation at the single protein level: pH sensing in the bacterial channel OmpF
(The Royal Society of Chemistry, 2014)
The pH sensing mechanism of the OmpF channel operates via ligand modification: increasing acidity induces the replacement of cations with protons in critical binding sites decreasing the channel conductance. Aside from the ...
