AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Dye sensitized solar cells based on annealed titanium dioxide films prepd. by oblique reactive d.c. magnetron sputtering have been investigated. Electron transport and recombination were studied using intensity-modulated photocurrent and photovoltage spect ...
Five novel perylene mols. with different intramol. charge-transfer (ICT) characters have been synthesized. The relation between the ICT character for different donating groups and the results for their electro- and photochem. properties as well as their pe ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
Ionic liquids have been identified as a new class of solvent that offers opportunities to move away from the traditional solvents. The physical-chemical properties of ionic liquids can be tuned and controlled by tailoring their structures. The typical prop ...
Through introducing an energy antenna system into a simple phenoxazine dye (TH301), a novel and efficient dye TH305 was designed and synthesized for application in a dye sensitized solar cell with prominent overall conversion efficiency of 7.7%. ...
The present invention relates to optoelectronic and/or electrochemical devices comprising an organic charge transporting material which is liquid at a temperature of =180 DEG C. In particular in dye-sensitised solar cells, quantum efficiency higher than wi ...
The transport and recombination of electrons in dye-sensitized TiO2 solar cells were studied by anal. of the current and voltage response to a small square-wave light-intensity modulation. Solar cells were studied under working conditions by using potentio ...
Nanostructured TiO2 films were modified by insertion with Al ions using an electrochem. process. After heat treatment these films were suitable as electrodes in dye-sensitized solar cells. By a catechol adsorption test and with photoelectron spectroscopy , ...
The first single molecule fluorescence resonant energy transfer scanning near-field optical microscope (FRET SNOM) images of CdSe nanocrystal (donor) deposited onto the glass slide surface are presented. Images were obtained using the earlier proposed FRET ...
A tool for ray tracing simulations of quantum dot solar concentrators is developed on the basis of Monte-Carlo methods that are applied to polarization-dependent reflection/transmission at interfaces, photon absorption by the semiconductor nanocrystals and ...
