One-electron outer-sphere redox couples, such as ferrocene/ferrocenium, are an interesting alternative to the iodide/triiodide redox couple that is normally employed in dye-sensitized solar cells (DSCs) because they should reduce the driving force needed t ...
Metal-free org. dyes bridged by anthracene-contg. π-conjugations were designed and synthesized as new chromophores for dye-sensitized solar cells (DSSCs). Studies on the relation between the dye structure, photophys. properties, electrochem. properties and ...
The dye-sensitized solar cell (DSC) challenges conventional photovoltaics with its potential for low-cost prodn. and its flexibility in terms of color and design. Transient absorption spectroscopy is widely used to unravel the working mechanism of DSCs. A ...
Dye-sensitized solar cells (DSCs) with Co-based mediators with efficiencies surpassing the record for DSCs with iodide-free electrolytes were developed by selecting a suitable combination of a Co polypyridine complex and an org. sensitizer. The effect of t ...
The article presents DFT calcns. that elucidate the interaction of a redox mediator, iodide/triiodide, and an oxidized org. dye photo-sensitizer, providing electronic structure insight into all steps of the mechanism involved in dye-sensitized solar cells. ...
Four metal-free org. sensitizers (TC101-TC104) with triple bonds in π-spacers and 5 ref. dyes (TC, TC105, TPC1, D5, and TH208) without triple bonds were applied in dye-sensitized solar cells to study the influence of triple bonds as π-spacer units on their ...
A series of dyes based on a triphenylamine donor and a rhodanine acetic acid anchor/acceptor for solar cell application has been studied with regards to electron injection and recombination kinetics using femtosecond transient absorption. The series contai ...
Three donor-linker-acceptor triphenylamine-based cyanoacrylic acid org. dyes used for dye-sensitized solar cells (DSCs) were examd. with respect to their effect on the open-circuit voltage (Voc). The previous study showed a decrease in Voc for DSCs based o ...
Photoinduced energy conversion from multilayers of org. dye on dense TiO2 films was investigated in bilayer hybrid solar cells. Dye layers of varying thicknesses were prepd. by spin-casting the star-shaped dye [tris(dicyano-vinyl-2-thienyl)phenyl]amine fro ...
Three triphenylamine-based org. sensitizers with different electron-donating substituents (butoxyl chains or dimethylamine groups) were examd. to investigate the effect of bulky alkoxy donor substituents on the photovoltaic performances of dye-sensitized s ...
