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 ...

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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
