An org. chromophore D5 (3-(5-(4-(diphenylamino)styryl)thiophene-2-yl)-2-cyanoacrylic acid) was tested as a sensitizer in photoelectrochem. mesoporous ZnO solar cells. Using thin (∼3 μm) mesoporous ZnO electrodes, high incident photon-to-current conversion ...
We report exptl. results concerning the STM imaging of cis-bis (isothiocyanate)-bis-(2,2'-bipyridyl-4,4'dicarboxylate)ruthenium(II)bis(tetrabutylammonium) dye (known as N719) adsorbed on a single crystal of anatase TiO2(100). The cleaning pretreatment, by ...
The P1- or C343-sensitized NiO photocathodes for p-DSSCs were optimized to obtain substantial current from thin films prepd. in two steps rather than one. These films are capable of adsorbing more dye, in comparison to one step films with the same thicknes ...
Three new sensitizers for photoelectrochem. solar cells were synthesized consisting of a triphenylamine donor, a rhodanine-3-acetic acid acceptor and a polyene connection. The conjugation length was systematically increased, which resulted in two effects. ...
In this letter, we report on an efficient org. tandem solar cell combining a solid state dye-sensitized with a ZnPc / C 60 -based, vacuum deposited bulk heterojunction solar cell. Due to an effective serial connection of both subcells and to the complement ...
In the field of dye-sensitized solar cells the no. of different sensitizing dyes is increasing rapidly. To produce low-cost dyes, much work is being directed toward synthesizing all-org., Ru-free dyes with high extinction coeffs. and broad absorption bands ...
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 ...
A new perylene sensitizer, ID176, for dye-sensitized solar cells (DSCs) is presented. The dye has the capability for high photocurrents due to strong absorption from 400 to >700 nm. Photocurrents of up to 9 mA/cm2 were achieved in solid-state DSCs employin ...
The solar-to-elec. power-conversion efficiency (η) of dye-sensitized solar cells can be greatly enhanced by integrating a mesoporous, nanoparticle-based, one-dimensional photonic crystal as a coherent scattering layer in the device. The photogenerated curr ...
The efficiency of dye-sensitized nanocryst. solar cells contg. ionic liqs., composed of org. sulfonium or imidazolium iodides, or a std. org. liq.-based electrolyte was studied, using sensitizers based on different polypyridyl-Ru complexes. The dyes N-719, ...
