Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
With the increasing cognition of the importance of organic molecules, they are widely applied in printing, biological and pharmacological fields, because of their special capabilities of harvesting solar light, scavenging free radicals, and chelating metal ...
Dye-sensitized solar cells (DSCs) are considered as an emerging technology in order to replace conventional silicon solar cells or thin film solar cells such as amorphous silicon, CIGS, and CdTe. Liquid electrolytes containing iodide/triiodide redox couple ...
The dye-sensitized solar cell (DSC) challenges conventional photovoltaics with its potential for low-cost prodn. and its flexibility in terms of color and design. Transient absorption spectroscopy is widely used to unravel the working mechanism of DSCs. A ...
We demonstrate a general approach by which colloidal anatase TiO2 nanocrystals with anisotropically tailored linear and branched shapes can safely be processed into high-quality mesoporous photoelectrodes for dye-sensitized solar cells. A detailed study ha ...
A series of novel metal-free org. dyes TC301-TC310 with relatively high HOMO levels were synthesized and applied in dye-sensitized solar cells (DSCs) based on electrolytes that contain Br-/Br3- and I-/I3-. The effects of additive Li+ ions and the HOMO leve ...
Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...
An optimized unsymmetrical squaraine dye 5-carboxy-2[[3-[(2,3-dihydro-1, 1-dimethyl-3-ethyl-1H-benzo[e]indol-2-ylidene)methyl]-2-hydroxy-4-oxo-2-cyclobuten-1-ylidene]methyl]-3,3-dimethyl-1-octyl-3H-indolium (SQ02) with carboxylic acid as anchoring group is ...
We employ time-dependent density functional theory to study the optical properties of a squaraine sensitized TiO2 system, as a model for the corresponding dye-sensitized solar cell. The all-organic squaraine dye is particularly promising for light absorpti ...
This thesis presents two applications of 2,2'-bipyridine (bipy) derivatives, the first involves their use as stabilizers for nanoparticle (NP) catalysts and the second is concerned with the use of bipy ligands for ruthenium dye molecules applied in dye sen ...
A comprehensive theoretical study on the electronic absorption spectra of a representative group of organic dyes (L0, D4, D5, C217, and JK2) employed in dye-sensitized solar cell devices is reported. A benchmark evaluation on different time-dependent densi ...
