Resonance Raman scattering studies of a complete dye-sensitized solar cell (DSC) including iodine and lithium iodide in the electrolyte indicate that triiodide (I3-) exchange the SCN- ligand of the dye bis(tetrabutylammonium) cis-bis(thiocyanato)bis(2,2'-b ...
A dye sensitized solar cell, comprising a heteroleptic polypyridil complex of Ru, Os or Fe. The donating ligand has an extended conjugated À-system increasing the light absorbance and keeing the LUMO energy level higher than that of the anchoring ligand. A ...
(Ecole Polytechnique Federale De Lausanne (EPFI), Switz.).2006
We present an experimentally validated coupled optical and electrical model for the dye-sensitized solar cell. The light absorption and subsequent charge generation in the photoactive layer is calculated accurately using coherent and incoherent optics. The ...
A combined d. functional theory/continuum electrostatics approach was used to est. the pKa values of metal-based compds. and their hydrolysis products. Specifically, the protonation states and abs. pKa values of [M(h6-arene)(X)(Y)(pta)]n+ (M = Ru or Os; ar ...
By deliberately causing degrdn. of components in a dye-sensitized solar cell the authors have studied failure mechanisms of such cells. The dye, bis(tetrabutylammonium) cis-bis(thiocyanato)bis(2,2'-bipyridine-4-carboxylic acid, 4'-carboxylate)ruthenium(II) ...
N heterocyclic compds., such as N-methylbenzimidazole (MBI), are commonly used as additives to electrolytes for dye-sensitized solar cells (DSCs), but the chem. transformation of additives in electrolyte solns. remains poorly understood. Solid cryst. compd ...
Conversion of unactivated olefins to azides was achieved with high Markovnikov selectivity for a broad range of alkenes by using 6 mol % Co(BF4).6H2O and ligand I, with 3 equiv of tosyl azide as the nitrogen source and simple silanes (e.g., PhSiH3, tetrame ...
The reaction of (Et3P)PdCl2 with 2,3-dihydroxypyridine, 5-chloro-2,3,-dihydroxypyridine, or 2-hydroxynicotinic acid in the presence of base gives neutral, metallomacrocyclic compounds in which the heterocycles act as dianionic, bridging ligands. The m ...
