Citrazinic acid is used as a convenient starting material for both tridentate 2,6-di(pyrazol-1-yl)-pyridine and tetradentate 6,6'-di(pyrazol-1-yl)-2,2'-bipyridine ligands containing carboxylic groups useful for further anchoring of sensitizer on TiO2 for d ...
Zinc(II) phthalocyanine dyes that contain triarylamine-terminated bisthiophene and hexylbisthiophene groups have been synthesized by a convergent approach by using carboxytriiodoZnPc as a precursor. Further transformation of the iodo groups by a Pd-catalyz ...
We report herein lightweight, and economical dye-sensitized solar cells fabrication facilitated by an all plastic, metal free cathode consisting of poly(3,4-ethylenedioxythiophene). ...
An energy conversion efficiency of up to 5.24% has been attained, under AM 1.5 G illumination for a new dye-sensitized solar cell using TH305, as a low cost org. dye, ((CH3)4N)2S/((CH3)4N)2S2, as an org. electrolyte and CoS as counter electrode. ...
Metal-free org. dyes with a core phenoxazine chromophore have been synthesized and tested as sensitizers in dye-sensitized solar cells. Overall conversion efficiencies of 6.03-7.40% were reached under std. AM 1.5 G illumination at a light intensity of 100 ...
Tungsten dioxide (WO2) nanorods were synthesized, which showed good catalytic activity for the redn. of triiodide to iodide. The dye-sensitized solar cell (DSC) using WO2 as a counter electrode (CE) reached a high energy conversion efficiency of 7.25%, whi ...
A colloidal crystal-splitting growth regime was used in which TiO2 nanocrystals, selectively trapped in the metastable anatase phase, can evolve to anisotropic shapes with tunable hyper-branched topologies over a broad size interval. The synthetic strategy ...
TiC has been used as a counter electrode catalyst in place of Pt for triiodide redn. in dye-sensitized solar cells. Its catalytic activity can be comparable to that of Pt. The effect of the thickness of the TiC layer on the performance of the dye-sensitize ...
Synthesized niobium oxides (Nb2O5 and NbO2) were applied for the first time as counter electrodes (CEs) in dye-sensitized solar cells (DSCs). The DSC using NbO2 CE showed a higher power conversion efficiency of 7.88%, compared with that of the DSC using Pt ...
