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.
Nanocryst. particles of ZnO and TiO2 of approx. equal size (∼15 nm) were used to prep. mesoporous electrodes for dye-sensitized solar cells. Electron transport in the solar cells was studied using intensity-modulated photocurrent spectroscopy and revealed ...
Dinuclear class II CoIII/FeII mixed-valence complexes, [LnCoIII(μ-NC)FeII(CN)3L2]m-, where Ln represents a pentadentate macrocycle and L2 a bpy ligand or 2 cyanides, have electronic properties that make them possible sensitizers in dye sensitized solar cel ...
A heteroleptic polypyridyl ruthenium complex, cis-Ru(4,4-bis(5-octylthieno[3,2-b]thiophen-2-yl)-2,2-bipyridine)(4,4-dicarboxyl-2,2-bipyridine)(NCS)2, with a high molar extinction coefficient of 20.5 × 103 M-1 cm-1 at 553 nm has been synthesized and demonst ...
A perylene imide sensitizer and a covalently-linked perylene imide-naphthalene diimide dyad were prepd. and characterized by absorption and emission spectroscopies, electrochem., and spectroelectrochem. These compds. were chemisorbed on nanoporous Ni oxide ...
A phenomenally high molar extinction coefficient heteroleptic ruthenium(II) complex [Ru(4,4′-carboxylic acid-2,2′- bipyridine)(4,4′-(4-{4-methyl-2,5-bis[3-methylbutoxy]styryl}-2,5-bis[3- methylbutoxy]-2,2′-bipyridine)(NCS)2] (DCSC13) was synthesized by inco ...
A novel dye (2TPA-R), contg. two triphenylamine (TPA) units connected by a vinyl group and rhodanine-3-acetic acid as the electron acceptor, is designed and synthesized successfully to reveal the working principles of org. dye in dye-sensitized solar cells ...
The surface electronic and mol. structure of a new org. chromophore useful for dye-sensitized nanostructured solar cells was studied by electron spectroscopy. Initially the use of a simple mol. system contg. the polyene-diphenylaniline chromophore in a sol ...
Parylene films loaded with TiO2 are reported as hotocatalysts in azo dye discoloration processes. The TiO2 loading of the parylene film was 0.32% (w/w) and the amount of TiO2 on the film was about two orders of magnitude below the TiO2 added in suspension ...
Nanoporous, p-type NiO films were sensitized with Coumarin 343 (C343), and the photoinduced electron transfer dynamics was studied in the presence of different concns. of electrolyte (I3-/I- in propylene carbonate). Electron transfer from the valence band ...
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 , ...
