The low-pressure cold microwave (MW) plasma is shown as an efficient method to increase acidity of the ACF within less than 1 min treatment without affecting the fiber morphol. and strength. The ion-exchange capacity was 1.6 times higher compared to the no ...
In this paper, we present a simulation platform designed to study coupled charge transport in dye-sensitized solar cell (DSC) devices. The platform, SLICE, is used to study the influence of ions in the electrolyte on electron transport in the nanoporous me ...
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 ...

A model to study charge transport processes in mesoporous films of dye-sensitized solar cells is presented. By simulating electron and ion transport by Brownian dynamics in these films, a direct relation between grain connectivity and effective diffusion c ...
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 novel method for anchoring phthalocyanines substituted with ester groups onto nanostructured TiO2 films is described. Such phthalocyanines did not adsorb on nanostructured TiO2 film by the ordinary methods. In the authors' new method, the TiO2 film is pr ...
Although there are many conceivable ways to functionalize, and specifically carboxylate, 2-chloro-4-(trifluoromethyl)pyridine optionally at all three vacant positions, it is more straightforward to prep. only 2-chloro-4-(trifluoromethyl)pyridine-3-carboxyl ...
A dye sensitized solar cell, wherein a compacting compound whose molecular structure comprises a terminal group, a hydrophobic part and an anchoring group is co-adsorbed together with the dye on the semi-conductive metal oxide layer of the photoanode, form ...
Ionic liquids containing the nitrile and vinyl functional groups attached to imidazolium cations combined with various anions, e.g., iodide, bis[(trifluoromethyl)sulfonyl]imide ([TFSI]-), or dicyanamide ([N(CN)2]-), have been prepared and characterized. Th ...
Org. chromophores were synthesized to approach optimal energy level compn. in the TiO2-dye-iodide/triiodide system in the dye-sensitized solar cells. HOMO and LUMO energy level tuning is achieved by varying the conjugation between the triphenylamine donor ...
