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.
The interaction between the dye cis-bis(4,4'-dicarboxy-2,2'-bipyridine)-bis(isothiocyanato) ruthenium(II), Ru(dcbpyH2)2(NCS)2, and nanostructured ZnO was investigated by photoelectron spectroscopy (PES) using synchrotron radiation. The results are compared ...
Nanoporous ZnO electrodes, dye-sensitized with a ruthenium bipyridyl complex, were used as photoanodes in photoelectrochem. solar cells. By improving the interfacial contact between dyes and ZnO particles in the film, overall solar-to-elec. energy conversi ...
The present paper describes a new method for manufg. a nanostructured porous layer of a semiconductor material at room temp. The porous layer is pressed on a conducting glass or plastic substrate for use in a dye-sensitized nanocryst. solar cell. The metho ...

An antenna which combines solar cells and printed patches is presented. The antenna is designed so as to accommodate the solar cells that provide power to an MMIC amplifier. A 2×4 array which operates at the frequency of 3.76 GHz and has a bandwidth of 16% ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, comprises the steps of: prepg. a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent , depositing the particle suspension on a ...
Nanocryst. titanium oxide films were prepd. by DC magnetron sputtering onto SnO2:F-coated glass substrates kept at temps. in the 50 < τs < 300° range. Dye sensitization in cis-dithiocyanato-bis(2,2'-bipyridyl-4,4'-dicarboxylate) ruthenium(II) yielded solar ...
Hydrogenated microcrystalline silicon prepared at low temperatures by the glow discharge technique is examined here with respect to its role as a new thin-film photovoltaic absorber material. XRD and TEM characterizations reveal that microcrystalline silic ...
Nanocryst. solar cells were made by incorporation of cis-dithiocyanato-bis(2,2'-bipyridyl-4,4'-dicarboxylate) ruthenium (II) into sputter deposited titanium oxide films. After a pyridine treatment, it was possible to achieve a photoelec. conversion efficie ...
Thin films consisting of nanorods of hematite (α-Fe2O3) with controlled orientation onto transparent conductive glass substrates have been tested as photoelectrochem. cells. These films allow a more efficient transport and collection of photogenerated elec ...
