In this paper, we present a simulation platform designed to study coupled charge transport in dye-sensitized solar cell (DSC) devices. The platform, SLICE, is used to study the influence of ions in the electrolyte on electron transport in the nanoporous me ...
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 ...
A model to study charge transport processes in mesoporous films of dye-sensitized solar cells is presented. By simulating electron and ion transport by Brownian dynamics in these films, a direct relation between grain connectivity and effective diffusion c ...
A novel and efficient polyene-diphenylaniline dye for dye-sensitized solar cells was synthesized. The dye has a short synthesis route and is readily adsorbed on TiO2 under a variety of dye-bath conditions. The overall solar-to-energy conversion efficiency ...
The prevailing prodn. method for dye-sensitized solar cells is based on the screen-printing technique. To find an alternative method, allowing very high throughput, we have looked into the possibility of developing a continuous prodn. process. A prerequisi ...
A dye sensitized solar cell, comprising a heteroleptic polypyridil complex of Ru, Os or Fe. The donating ligand has an extended conjugated À-system increasing the light absorbance and keeing the LUMO energy level higher than that of the anchoring ligand. A ...

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 ...
Ionic liquids containing the nitrile and vinyl functional groups attached to imidazolium cations combined with various anions, e.g., iodide, bis[(trifluoromethyl)sulfonyl]imide ([TFSI]-), or dicyanamide ([N(CN)2]-), have been prepared and characterized. Th ...
