Three anthraquinone dyes with carboxylic acid as anchoring group are designed and synthesized as sensitizers for dye-sensitized solar cells (DSSCs). Preliminary photophys. and photoelectrochem. measurements show that these anthraquinone dyes have very low ...
The relation between the VOC, light intensity, φ, and accumulated charge, Q, was studied for dye-sensitized solar cells (DSCs) contg. different counterions for the iodide/triiodide redox couple. At higher light intensities, VOC scaled in the order Cs+ > K+ ...
Dye-sensitized solar cells (DSCs) based on nanocrystalline TiO2 have been fabricated with an amphiphilic ruthenium sensitizer NaRu(2,2'-bipyridine-4-carboxylic acid-4'-carboxylate)(4,4'-dinonyl-2,2'-bipyridine)(NCS)2, coded as Z-907, and a series of -guani ...
Two org. dyes with the general structure donor-conjugated chain-acceptor (D-π-A) were studied as sensitizers for nanocryst. TiO2 solar cells. The electron donor and acceptor groups were pyrrolidine and cyano acrylic acid, resp. The conjugated chain of 2-cy ...
Eleven novel donor acceptor π-conjugated (D-π-A) org. dyes were engineered and synthesized as sensitizers for the application in dye-sensitized solar cells (DSSCs). The electron-donating moieties are substituted tetrahydroquinoline, and the electron-withdr ...
The authors report on the prepn. of interhalogen ionic liqs. [K+]XY2-, where K+ = 1,3-dialkylimidazolium, 1,2,3-trialkylimidazolium, or N-alkylpyridinium; XY2- = IBr2- or I2Br-. These compds. were characterized in soln. and the solid state by NMR, IR, Rama ...
N heterocyclic compds., such as N-methylbenzimidazole (MBI), are commonly used as additives to electrolytes for dye-sensitized solar cells (DSCs), but the chem. transformation of additives in electrolyte solns. remains poorly understood. Solid cryst. compd ...
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 ...
Dye-to-semiconductor electron transfer is the initial step in many processes where light is used for the storage of information (e. g. color photography) or converted into electricity as in dye-sensitized solar cells. In the latter, interfacial charge inje ...
Novel organic sensitizers comprising donor; electron-conducting, and anchoring groups were engineered at molecular level and synthesized. The functionalized unsymmetrical organic sensitizers 3-{5-[N,N-Bis(9,9-dimethylfluorene-2-yl)phenyl]-thiophene-2-yl}-2 ...
