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.
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 ...
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 ...
The investigation of the use of cyanine dyes in thin-film heterojunction photovoltaic devices was reported. It was shown that a carbocyanine dye acts as donor in conjunction with buckminsterfullerene (C60). Cyanine acts as acceptor when copoly(dicyano-phen ...
Rylene derivs. are prepd. and described for use as photosensitizers for solar cells. These derivs., which have a high incident photon-to-current conversion efficiency, are esp. useful in solar cells for the decompn. of water into hydrogen and oxygen. ...

The electron transport in nanostructured TiO2 has been investigated in an electrochem. system using laser flash induced photocurrent transient measurements with addnl. continuous monochromatic bias light. Significant effects are found on the photocurrent t ...
There has been intense interest and debate concerning the electron transfer rates within dye-sensitized nanostructured n-type semiconductors (such as TiO2). The motivation for this research has been the development of solar cells in which the first step is ...
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 ...
Photoelectrochem. measurements have been performed on film electrodes consisting of linked nano-sized TiO2 colloids. The film thickness ranged from 1-40 μm. The film network was attached to a thin transparent conducting layer of SnO2 allowing for photogene ...
The photoelectrochem. properties of ZnO electrodes were studied in the near-UV region. Studies were carried out on electrodes with different morphologies, porosities, and film thicknesses to probe the influence of these parameters on the photoelectrochem. ...
Cyanine dyes with absorption edges of almost 1000 nm were used in combination with MEH-PPV for the fabrication of organic solar cells. For blended thin films, a pronounced phase separation between the two components occurred and resulted in photocurrents w ...
