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.
We have designed and developed an unsymmetrical zinc phthalocyanine (TT9) sensitizer that consists of three tert-butyl and two carboxylic acid groups that act as "push'' and "pull'', respectively. The two carboxylic acid groups graft the sensitizer onto th ...
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 ...
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 ...
Long-lasting charge separation is key to the performance of solar cells. A new design for larger conjugated dye-sensitizer molecules effectively retards the recombination of the charge-separated state and promises improved energy conversion effi ciency. ...
The effect of RC attenuation was not correctly taken into account. This led to a misinterpretation of the photocurrent response data that was in Figure 3a on page 17717 and further discussion. Under operating conditions, electrons are accumulated throughou ...
In this work, we analyze the effect of rough ZnO front electrodes developed in-house favoring high current versus "smoother" substrates favoring good Voc and FF on the properties of microcrystalline silicon (μc-Si:H) cells. Complete μc-Si:H p-i-n solar cel ...
This work evaluated the possibility of using silicon solar cells as load-carrying elements in composite sandwich structures. Such an ultra-light multifunctional structure is a new concept enabling weight, and thus energy, to be saved in high-tech applicati ...
Basic limitations of single-junction and tandem p-n and p-i-n diodes are established from thermodynamical considerations on radiative recombination and semi-empirical considerations on the classical diode equations. These limits are compared to actual valu ...
Specific interactions of the I-/I3- redox mediators with the reduced and oxidized dye, Ru(4,4'-dicarboxy-2,2'-bipyridyl)2(NCS)2, referred to as N3 or Ru(dcbpy)2(NCS)2, were studied by d. functional theory (DFT) with the focus on the charge transfer process ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, includes the steps of prepg. a suspension of semiconducting nanoparticles in a volatile suspension agent, depositing the particle suspension on a conducting subst ...
