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.
In recent years, the fabrication of novel ultrathin film systems featuring multi-functionalities has been extensively studied due to their potential applications in photonics, sensors and solar cells. In a general sense, the primary goal of the present the ...
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 ...
The invention provides a device for obtaining an improved efficiency in a photovoltaic, nanostructured, dye sensitized cell structure, comprising a photoactive working electrode, a counter electrode and an electrolyte arranged there-between. The cell struc ...
We report on the direct absorption measurement of the polarization selection rules in a V-groove QWR waveguide. Attenuation measurements in a 1 mm long waveguide were performed from 10 K up to room temperature. These measurements yielded the QWR DOS select ...
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 ...
A phenomenally high molar extinction coefficient heteroleptic ruthenium(II) complex [Ru(4,4′-carboxylic acid-2,2′- bipyridine)(4,4′-(4-{4-methyl-2,5-bis[3-methylbutoxy]styryl}-2,5-bis[3- methylbutoxy]-2,2′-bipyridine)(NCS)2] (DCSC13) was synthesized by inco ...
A review with 49 refs. The dye-sensitized nanocryst. injection solar cell employs transition metal complexes for spectral sensitization of mesoporous TiO2 films together with suitable redox electrolytes or amorphous org. hole conductors. Light harvesting o ...
During the past five years, we have developed in our laboratory a new type of solar cell that is based on a photoelectrochemical process. The light absorption is performed by a monolayer of dye (i.e., a Ruthenium complex) that is adsorbed chemically at the ...
