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.
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 ...
Five novel perylene mols. with different intramol. charge-transfer (ICT) characters have been synthesized. The relation between the ICT character for different donating groups and the results for their electro- and photochem. properties as well as their pe ...
An org. chromophore D5 (3-(5-(4-(diphenylamino)styryl)thiophene-2-yl)-2-cyanoacrylic acid) was tested as a sensitizer in photoelectrochem. mesoporous ZnO solar cells. Using thin (∼3 μm) mesoporous ZnO electrodes, high incident photon-to-current conversion ...
High incident photon-to-current conversion efficiency of p-type dye-sensitized solar cells are based on transparent NiO films and org. chromophores [4-(bis-[4-[5-(2,2-dicyanovinyl)thiophene-2-yl]phenyl)amino]benzoic acid] and [4-(bis[4'-(2,2-dicyanovinyl)b ...
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 ...
A model for the design of efficient dyes for p-type dye-sensitized solar cells (DSSCs) is presented. As an example, a novel and efficient org. dye contg. a triphenylamine chromophore was synthesized and applied in a p-type DSSC. An incident photon-to-curre ...
A tandem cell or photoelectrochemical system for the cleavage of water to hydrogen and oxygen by visible light has two superimposed photocells, both cells being connected electrically. The photoactive material in the top cell is a semiconducting oxide plac ...
In this letter, we report on an efficient org. tandem solar cell combining a solid state dye-sensitized with a ZnPc / C 60 -based, vacuum deposited bulk heterojunction solar cell. Due to an effective serial connection of both subcells and to the complement ...
Finely tuned: A stable dye-sensitized solar cell that contains a molecularly engineered org. dye was prepd. The efficiency of the cell remains at 90% after 1000 h of light soaking at 60°. The remarkable stability of the cell is also reflected in the open-c ...
Five ionic liqs. (ILs) Im+A-, where Im+ = 1-methyl-3-n-butyl-imidazolium, A- = I- (1), BF4- (2), SCN- (3), CF3CO2- (4), and CF3SO3- (5), were used in electrolytes for dye-sensitized monolithic solar cells. The properties of the electrolytes and various cha ...
