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.
Tandem solar cells, in which two individual cells are stacked on top of each other, offer the potential to increase the efficiency significantly compared to a single cell on the same area. To reach maximum efficiency, each cell in the stack must have a dis ...
The solar to electrical power conversion efficiency for dye-sensitized solar cells (DSCs) incorporating a solid-state organic hole-transporter can be over 5%. However, this is for devices significantly thinner than the optical depth of the active composite ...
Products of thermal dehydrogenation of C60H18 (which mainly occurs at 450-600 degrees C) were studied by XRD, Raman, IR and mass spectrometry. IR spectra indicate that dehydrogenation resulted in partial recovery of pristine C-60. XRD data indicate that th ...
Dyes with a similar structure, i.e., a combination of triphenylamine with cyanovinylenethiophene, have been synthesized before and have been used in different applications according to Spraul et al., (2004); Roquet et al., (2006); and Hagberg et al., (2006 ...
In Feburary 2008, the oil price easily exceeded $ 100 per barrel due to the weak US dollar and the imbalance between the increasing demands and deficient supplies. People are paying more and more attention to seek for alternative energy sources that would ...
Tandem solar cells, in which two individual cells are stacked on top of each other, offer the potential to increase the efficiency significantly compared to a single cell on the same area. To reach maximum efficiency, each cell in the stack must have a dis ...
We present a device based study into the operation of liquid electrolyte dye-sensitized solar cells (DSSC's) using organic dyes. We find that, for these systems, it is entirely necessary to employ a compact TiO2 layer between the transparent fluorine doped ...
Two novel hybrid sensitizers incorporating an organic antenna into a ruthenium complex have been synthesized and applied successfully in nanocrystalline TiO2 based solar cells, which yielded solar to electricity conversion efficiencies of 8.20-9.16% under ...
A perylene imide sensitizer and a covalently-linked perylene imide-naphthalene diimide dyad were prepd. and characterized by absorption and emission spectroscopies, electrochem., and spectroelectrochem. These compds. were chemisorbed on nanoporous Ni oxide ...
The performance enhancement of dye-sensitized solar cells (DSCs) in lithium-free and lithium-containing electrolytes under visible light-soaking was examined by impedance spectroscopy and photovoltage transient decay measurements. The improvement was found ...
