We present a study of the kinetics of electron injection in ruthenium(II) cis-(2,2‘-bipyridyl-4,4‘-dicarboxylate)2(NCS)2-sensitized nanocrystalline TiO2 films as a function of electrical potential applied to the TiO2 film and as a function of the compositi ...
Dye-sensitized nanocryst. TiO2 solar cells are currently under development. Since these cells contain an electrolyte soln. we reviewed the health and safety aspects in view of indoor applications, where personal contact cannot be excluded. Only small amts. ...
Methods for the prepn. and purifn. of new carboxylated 2,2'-bipyridine ligands, two of which contain the new anchoring functionality malonate, and a reliable method for the synthesis of the corresponding Ru(bpy)2(L)2 complexes are described. Their s ...
A new heteroleptic polypyridyl ruthenium complex (see Figure) with a high molar extinction coefficient has been synthesized. The complex is demonstrated to be a highly efficient, stable sensitizer for nanocrystalline dye-sensitized solar cells. For a newly ...
Potential new electrolytes for dye-sensitized nanocryst. solar cells (DNSCs) of Graetzel type based on trialkylsulfonium iodides were studied. Room temp. molten salts of (Et2MeS)I, (Bu2MeS)I, and (Bu2EtS)I, with iodine in low concns., revealed good conduct ...
The objective of this work was to develop a solid-state dye-sensitized solar cell, in which the liquid electrolyte, commonly applied in photoelectrochemical cells, is replaced by a solid organic charge transport material (spiro-OMeTAD). The dye-sensitized ...
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) ...
An electrolytic cell assembly, e.g. for use in solar panels, is formed by placing coated metal wires between the conducting layers of two conducting glasses, resp. A pressure force is applied to press the metal wires between the conducting layers and to br ...
A review with 156 refs. on interfacial electron transfer reactions in colloidal semiconductor solns. and thin films and their application for solar light energy conversion and photocatalytic water purifn. Some of the topics discussed include; optical and e ...
The laser induced photocurrent transient and capacitance measurements were used to study the charge carrier sepn. and charge transport in single-crystal porous TiO2 electrodes. The fast photocurrent component was due to the transport of free electrons thro ...
