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.

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 ...
Selective modification of zirconium alkoxide by acetic acid or acetylacetone was used in solution processing of PZT Pb(Zr,Ti)O-3 thin films by 2-methoxyethanol route. EXAFS results clearly show a decrease of Zr-O-Zr links in the acetic acid modified PZT so ...
PLZT x/65/35 (x = 4, 8, 10) thin films were prepared by the acetic-acid based chemical solution deposition processing from lead tetraacetate, lanthanum nitrate and zirconium and titanium propoxides. Introducing top layer of PLZT with large PbO excess can p ...
Aliovalent Nb doping (less than or equal to 10 at.%) of sol-gel-derived lead zirconate titanate (PZT) thin films was investigated with the intention of improving the ferroelectric properties. Nb addition was found to significantly alter the perovskite crys ...
A process for producing at least one epitaxial, nanostructured thin film of metal oxide and/or a hydrated metal oxide on at least one substrate placed in a container and a substrate/thin film thereof, comprises placing the substrate at any location in the ...
The surface, interfaces and grain boundaries of a halide perovskite film carry critical tasks in achieving as well as maintaining high solar cell performance due to the inherently defective nature across their regime. Passivating materials and felicitous p ...
To achieve both high efficiency and long-term stability of perovskite solar cells (PSCs), it is effective to use a perovskite layer in which a low-dimensional perovskite layer is stacked on a 3D perovskite layer. However, the guidelines for the effective s ...
CuIn1-xGaxSe2 (CIGS) solar cells show a good spectral response in a wide range of the solar spectrum and the bandgap of CIGS can be adjusted from 1.0 eV to 1.7 eV by increasing the gallium-to-indium ratio of the absorber. While the bandgaps of Ga-rich CIGS ...
