Graph Chatbot
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.
Hematite is a promising material for solar energy conversion via photo-electrochemical water splitting. However, the precise control of substitutional doping and nanometer feature size is important for high photon harvesting efficiency. Doped and nanostruc ...

In the context of the diminishing fossil energy resources and global warming, much research is focused on sustainable energy sources. The research that is presented in this thesis falls in this category as it contributes to the development of a device that ...
Due to the limiting amount of fossil fuel available and to the continuous growth of the world energy consumption, it becomes important to find alternative energy sources. Hydrogen produced by the photoelectrolysis of water is a perfect candidate as a clean ...
This thesis presents a new type of photovoltaic solar cell based on dye-sensitized nanocrystalline titanium dioxide electrodes. In contrast to conventional solar cells, where light absorption is due to band gap excitation of the semiconductor itself, TiO2 ...
Using sun as the energy source, natural photosynthesis carries out a number of useful reactions such as oxidation of water to molecular oxygen and fixation of CO2 in the form of sugars. These are achieved through a series of light-induced multielectron-tra ...
A fully conjugated unsymmetrical dimeric squaraine dye was synthesized. The synthetic key step for this dye, a selective Knoevenagel type condensation of end groups to the core moiety, allows the incorporation of a carboxylic acid function essentially for ...
L'inconvénient de cellules du type photoélectrochimique (1) est que leur rendement est insuffisant pour une utilisation économique. L'invention a pour objet d'éliminer cet inconvénient. Selon l'invention, le procédé permet de réaliser une cellule photoélec ...
