Relaxation of Photogenerated Carriers in P3HT:PCBM Organic Blends
(Wiley, 2009)
Relaxing in the sunlight. Long time-transient decays of photogenerated carriers in P3HT:PCBM blends for organic solar cells are interpreted in terms of the relaxation of hole carriers in a broad density of states.

Electron Transport in Dye-Sensitized Solar Cells Based on ZnO Nanotubes: Evidence for Highly Efficient Charge Collection and Exceptionally Rapid Dynamics
(American Chemical Society, 2009)
Dye-sensitized solar cells based on ordered arrays of polycrystalline ZnO nanotubes, 64 μm in length, are shown to exhibit efficient electron collection over the entire photoanode array length. Electrochemical impedance ...
Electron Transport and Recombination in Solid-State Dye Solar Cell with Spiro-OMeTAD as Hole Conductor
(American Chemical Society, 2009)
We show that electron transport mechanisms in TiO2 solid-state dye-sensitized solar cells (SDSCs) with spiro-OMeTAD as hole conductor are similar to those of high-performance DSCs with liquid electrolytes and ionic liquids. ...
Quatsomes: Vesicles Formed by Self-Assembly of Sterols and Quaternary Ammonium Surfactants
(American Chemical Society, 2013)
Thermodynamically stable nanovesicle structures are of high interest for academia and industry in a wide variety of application fields, ranging from preparation of nanomaterials to nanomedicine. Here, we show the ability ...
Properties of Chromophores Determining Recombination at the TiO2–Dye–Electrolyte Interface
(American Chemical Society, 2013)
Different classes of chromophores have been developed for the dye solar cell (DSC), including as the two main classes organometallic dyes, with Ru-based complexes and Zn-porphyrin complexes, and metal-free dyes. They result ...
Core/Shell Colloidal Quantum Dot Exciplex States for the Development of Highly Efficient Quantum-Dot-Sensitized Solar Cells
(American Chemical Society, 2013)
Searching suitable panchromatic QD sensitizers for expanding the light-harvesting range, accelerating charge separation, and retarding charge recombination is an effective way to improve power conversion efficiency (PCE) ...
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
