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.
The dye solar cell, is a novel photoelectrochemical solar cell presenting unique advantages, as the use of low cost materials and the potential simplicity of manufacturing. However, a liquid electrolyte is actually required for the transport of the photoge ...
The anchoring of the ruthenium dye {(C4H9)4N}[Ru(Htcterpy)(NCS)3] (tcterpy = 4,4',4''-tricarboxy-2,2':6',2''-terpyridine), the so-called black dye, onto nanocryst. TiO2 films has been characterized by UV-visible and FTIR spectroscopies. FTIR spectroscopy d ...
A review. Recent work on the charge transport in mesoscopic nanostructured film electrodes is summarized. Results from intensity-modulated photocurrent spectroscopy (IMPS) and intensity-modulated photovoltage spectroscopy (IMVS) studies are given, and the ...
A novel family of room temperature ionic liquids, N,N-diethyl-N′,N′-dipropyl-N′′-hexyl-N′′-methylguanidinium iodide (SGI) and N,N,N′,N′-tetramethyl-N′′,N′′-dipentylguanidinium tricyanomethanide (SGTM) were designed and synthesized. Due to the strong charge ...
A new heteroleptic polypyridyl ruthenium complex (see Figure) with a high molar extinction coefficient has been synthesized. The complex is demonstrated to be a highly efficient, stable sensitizer for nanocrystalline dye-sensitized solar cells. For a newly ...
Photoinduced electron transfer from the valence band of nanocryst. NiO, a p-type semiconductor, to an excited bound dye, Coumarin 343, and the subsequent recombination have been measured by femtosecond transient absorbance spectroscopy probing with white l ...
We show that a combination of a dye and a nanostructured NiO thin film on a conducting substrate can form a dye-sensitized photocathode that can be an active part in a tandem dye-sensitized solar cell (TDSC). To exptl. demonstrate a dye-sensitized nanostru ...
