Three dimensional-TiO2 nanotube array photoanode architectures assembled on a thin hollow nanofibrous backbone and their performance in quantum dot-sensitized solar cells
(Royal Society of Chemistry, 2013-02-18)
Facile synthesis of TiO2 nanotube branched (length [similar]0.5 μm) thin hollow-nanofibers is reported. The hierarchical three dimensional photoanodes (H-TiO2-NFs) (only [similar]1 μm thick) demonstrate their excellent ...
Elucidating Capacitance and Resistance Terms in Confined Electroactive Molecular Layers
(American Chemical Society, 2013)
Electrochemical analyses on confined electroactive molecular layers, herein exemplified with electroactive self-assembled monolayers, sample current contributions that are significantly influenced by additional nonfaradaic ...
Ion transport through biological channels
(Institut d’Estudis Catalans, 2015)
The transport of ions across single-molecule protein nanochannels is
important both in the biological context and in proposed nanotechnological applications.
Here we discuss these systems from the perspective of ...
Interplay Between Fullerene Surface Coverage and Contact Selectivity of Cathode Interfaces in Organic Solar Cells
(ACS Publications, 2013-04)
Interfaces play a determining role in establishing the degree of carrier selectivity at outer contacts in organic solar cells. Considering that the bulk heterojunction consists of a blend of electron donor and acceptor ...
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) ...
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 ...
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 ...
Ultrafast characterization of the electron injection from CdSe quantum dots and dye N719 co-sensitizers into TiO2 using sulfide based ionic liquid for enhanced long term stability
(Elsevier, 2013)
Combination of inorganic quantum dots (QDs) and organic/metallorganic dyes as supracollectors nanocomposites could have an important role on the development of efficient photovoltaic devices based on the synergistic action ...
Temperature effects in dye-sensitized solar cells
(Royal Society of Chemistry, 2013)
In the standard solar cell technologies such as crystalline silicon and cadmium telluride, increments of
temperature in the cell produce large variations in the energy conversion efficiency, which decreases at a
constant ...
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. ...
