Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Microcrystalline hydrogenated silicon growth with VHF-PECVD was examined in an industrial type parallel plate KAITM reactor. The influence of pressure on material quality was studied in single junction solar cells. Solar cells with their intrinsic layer pr ...
Increasing the efficiency of crystalline silicon (c-Si) solar cells requires the reduction of both bulk and interface recombination. Even if bulk recombination is almost suppressed, the symmetry of the crystal lattice is disturbed at the surface and hence, ...
The invention relates to ÿ-substituted porphyrins, methods for their synthesis, and their use in the preparation of photoelectric materials. In particular, the invention relates to solid state photoelectric devices, including solar cells and photodetectors ...
Gas barrier coatings based on single or multiple layers of metals, oxides or nitrides are widely used on polymer substrates in applications ranging from food packaging to organic displays and solar cells. These coatings exhibit a residual permeability resu ...
Long-lasting charge separation is key to the performance of solar cells. A new design for larger conjugated dye-sensitizer molecules effectively retards the recombination of the charge-separated state and promises improved energy conversion effi ciency. ...
A method for anchoring unsym. phthalocyaninato-metal complexes (metal ion: zinc and ruthenium) is described. The synthesis and characterization of these complexes, ZnL and Ru(4-picoline)2L (H2L = 2,3-bis(carboxyphenoxy)-9,10,16,17,23,24-hexakis(pentoxy)pht ...
Zinc oxide (ZnO) is a material that belongs to the family of Transparent Conductives Oxides (TCO). Its non-toxicity and the abundant availability in the Earth's crust of its components make it an ideal candidate as electrical transparent contact for thin-f ...
Undoped hydrogenated amorphous silicon layers deposited at different values of very high frequency (VHF) powers and silane to hydrogen dilution ratios possess various types of microstructures. Transport and defect measurements on layers suggest that struct ...
This paper describes a new method for manufg. a nanostructured porous layer of a semiconductor material at room temp. The porous layer is pressed on a conducting glass or plastic substrate for use in a dye-sensitized nanocryst. solar cell. The method compr ...
The microstructure and open-circuit voltage of n-i-p microcrystalline silicon solar cells were discussed. A mixed phase layer consisting of amorphous plus microcrystalline material was observed at the bottom of the solar cell and identified as one of the k ...
