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.
Dye-sensitized photoelectrochem. solar cells constitute a promising candidate in the search for cost-effective and environment-friendly solar cells. The most extensively studied, and to date the most efficient systems are based on titanium dioxide. In this ...
Hexanethiolate monolayer-protected gold nanoclusters (MPCs) were used as redox quenchers at the polarizable water/1,2-dichloroethane (DCE) interface. Photocurrent responses originating from the heterogeneous quenching of photoexcited water soluble porphyri ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
We present a study of the kinetics of electron injection in ruthenium(II) cis-(2,2‘-bipyridyl-4,4‘-dicarboxylate)2(NCS)2-sensitized nanocrystalline TiO2 films as a function of electrical potential applied to the TiO2 film and as a function of the compositi ...
The photoelectrochem. behaviors of dye-sensitized nanoporous TiO2 solar cells are studied under influences of light intensity, redox couple concn., temp., different cations and water in the nonaq. soln. The value of the ideality factor of dyed nanoporous T ...
Over the past fifteen years dye-sensitised nanocrystalline solar cells have been the subject of intense research and development efforts. These systems provide a technically and economically credible alternative to classical p-n junction solar cells, reach ...
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 ...
Forward biasing of transparent nanocryst. TiO2 (anatase) films in Li ion contg. org. electrolytes leads to rapid and reversible coloration due to electron accumulation and Li+ intercalation in the anatase lattice. Absorption of > 90% light throughout the v ...
Charge sepn. in sintered colloidal TiO2 film electrodes was studied by action spectra in SCN-/(SCN)2- the UV region. Electrodes with different film thicknesses were studied. Current generation is most efficient close to the back contact. Monochromatic quan ...
