Chattez avec Graph Search
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.
High-efficiency flexible dye-sensitized solar cells were fabricated with a Ti-metal foil substrate for photo anode and using a Pt-electrodeposited counter electrode on ITO/polyethylene naphthalate (ITO/PEN); these devices were characterized by incident pho ...
During the past five years, we have developed in our laboratory a new type of solar cell that is based on a photoelectrochemical process. The light absorption is performed by a monolayer of dye (i.e., a Ruthenium complex) that is adsorbed chemically at the ...
Nanoporous films of cryst. anatase with intended application in dye-sensitized photovoltaic cells were studied by NMR cryoporometry, NMR diffusiometry, electron microscopy, and x-ray diffraction. The nanoparticles from which the films were subsequently sin ...
The dye solar cell, is a novel photoelectrochemical solar cell presenting unique advantages, as the use of low cost materials and the potential simplicity of manufacturing. However, a liquid electrolyte is actually required for the transport of the photoge ...
We perform in this paper a kinetic study of the photoelectrochemical responses of nanoporous thin photoactive films. The films were fabricated by by a layer-by-layer assembly of positively charged polyelectrolytes (poly-L- Lysine, pLys) and negatively char ...
We present a novel method for recording persistent holograms in doubly-doped LiNbO3. Simultaneous sensitization of the crystal by an inhomogeneous UV beam can result to 32 % diffraction efficiency recorded by red light in a 0.85 mm thick sample, while read ...

Effective transverse piezoelectric coefficient e(31,f) has been measured on (100)/(001) sol-gel Pb(ZrXTi1-X) thin films with compositions between 30% and 45% Zr. A maximum value of 8.07 +/- 0.36 C/m(2) at 40% Zr is found. The influence of the poling field ...
Laser flash induced photocurrent transient measurements were used to study the electron transport in nanostructured TiO2 (anatase) thin film electrodes in contact with an electrolyte. The shape and the time domain for the current transients are dependent o ...
