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 ...
Porous silicon (PS) thin films have been prepd. by electrochem. anodization of p-Si in HF-H2O-EtOH soln. and they have been used as substrate material for the prepn. of iridium oxide based electrodes (PS/IrO2) using the thermal decompn. technique. The morp ...
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 ...
We have designed and synthesized a new unsymmetrical zinc phthalocyanine based on 'push-pull' and extended pi-conjugation concept, PCH008. The new sensitizer was fully characterized by CHN anlysis, UV-Vis., fluorescence spectroscopies and cyclic voltammetr ...
Due to their high efficiencies and their potentially low production costs, dye-sensitized solar cells (DSSC) have attracted much attention during the last few years. The technology is based on a layer made of mesoscopic TiO2 film which significantly increa ...
Dye-sensitized solar cells (DSCs) are of interest because of their potential for low-cost solar energy conversion. Currently, the certified record efficiency of these solar cells is 11.1%, and measurements of their durability and stability suggest lifetime ...
Counter electrodes (CEs) of dye-sensitized solar cells (DSCs) can be prepared with different materials and methods. This review covers recent research on CEs using platinum, graphite, activated carbon, carbon black, single-wall carbon nanotubes, poly( 3,4- ...
Cobalt complexes supported by diglyoxime ligands of the type Co(dmgBF2)2(CH3CN)2 and Co(dpgBF2)2(CH3CN)2 (where dmgBF2 is difluoroboryl-dimethylglyoxime and dpgBF2 is difluoroboryl-diphenylglyoxime), as well as cobalt complexes with [14]-tetraene-N4 (Tim) ...
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 ...
The invention provides a device for obtaining an improved efficiency in a photovoltaic, nanostructured, dye sensitized cell structure, comprising a photoactive working electrode, a counter electrode and an electrolyte arranged there-between. The cell struc ...
