This thesis presents two applications of 2,2'-bipyridine (bipy) derivatives, the first involves their use as stabilizers for nanoparticle (NP) catalysts and the second is concerned with the use of bipy ligands for ruthenium dye molecules applied in dye sen ...
The surface electronic and mol. structure of a new org. chromophore useful for dye-sensitized nanostructured solar cells was studied by electron spectroscopy. Initially the use of a simple mol. system contg. the polyene-diphenylaniline chromophore in a sol ...
Parylene films loaded with TiO2 are reported as hotocatalysts in azo dye discoloration processes. The TiO2 loading of the parylene film was 0.32% (w/w) and the amount of TiO2 on the film was about two orders of magnitude below the TiO2 added in suspension ...
An optimized unsymmetrical squaraine dye 5-carboxy-2[[3-[(2,3-dihydro-1, 1-dimethyl-3-ethyl-1H-benzo[e]indol-2-ylidene)methyl]-2-hydroxy-4-oxo-2-cyclobuten-1-ylidene]methyl]-3,3-dimethyl-1-octyl-3H-indolium (SQ02) with carboxylic acid as anchoring group is ...
The transport and interfacial transfer of electrons in dye-sensitized solar cells utilizing the Co(dbbip)(2) (dbbip = 2,6-bis(l'-butylbenzimidazol-2'-yl)pyridine) redox couple as an alternative to the conventional I-3(-)/l(-) couple have been investigated ...
A comprehensive theoretical study on the electronic absorption spectra of a representative group of organic dyes (L0, D4, D5, C217, and JK2) employed in dye-sensitized solar cell devices is reported. A benchmark evaluation on different time-dependent densi ...
One-electron outer-sphere redox couples, such as ferrocene/ferrocenium, are an interesting alternative to the iodide/triiodide redox couple that is normally employed in dye-sensitized solar cells (DSCs) because they should reduce the driving force needed t ...
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) ...
Adsorption of phthalocyanines lacking conventional attaching substituents onto nanostructured TiO2 electrodes has been studied, and some of the important factors for sensitization have been identified. Tetradimethoxyphenyl phthalocyanine (2) and tetra-Ph p ...
Electron transport in dye-sensitized solar cells with varying mesoporous TiO2 film thicknesses was investigated using exptl. and computational methods. More specifically, photocurrent transients resulting from small-amplitude square-wave modulation of the ...
