Dye sensitized solar cells based on annealed titanium dioxide films prepd. by oblique reactive d.c. magnetron sputtering have been investigated. Electron transport and recombination were studied using intensity-modulated photocurrent and photovoltage spect ...
Five novel perylene mols. with different intramol. charge-transfer (ICT) characters have been synthesized. The relation between the ICT character for different donating groups and the results for their electro- and photochem. properties as well as their pe ...
The electron transport in dye-sensitized solar cells with a MOCVD (metal org. vapor deposition)-grown ZnO nanorod array (ZnO-N) or a mesoporous film prepd. from ZnO colloids (ZnO-C) as the working electrode was compared. The electrodes were of similar thic ...
A new method for the prepn. of nanostructured TiO2 films, based on the compression of a TiO2 powder is presented, and its relevance for the prodn. of dye-sensitized solar cells is discussed. By applying a pressure (>200 kg cm-2) on a film of TiO2 powder, a ...
The effect of RC attenuation was not correctly taken into account. This led to a misinterpretation of the photocurrent response data that was in Figure 3a on page 17717 and further discussion. Under operating conditions, electrons are accumulated throughou ...
A series of allyl-functionalized imidazolium salts are reported, including 1-allyl-3-ethylimidazolium iodide and 1-allyl-3-propylimidazolium iodide, which have m.ps. close to room temp. and show typical properties of supercooled fluids if heated above thei ...
A comparison of the properties of the 2-thienyl-substituted carboxyphenyl {RuII(terpy)2} dyes with their non-substituted analogs has enabled us to gain insight into the electronic properties that are prerequisite for efficient electron injection into the T ...
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 ...
The transport and recombination of electrons in dye-sensitized TiO2 solar cells were studied by anal. of the current and voltage response to a small square-wave light-intensity modulation. Solar cells were studied under working conditions by using potentio ...
Photoinduced absorption (PIA) spectroscopy was used to investigate dye-sensitized electrodes and solar cells under illumination conditions comparable to sunlight. In the absence of redox electrolyte, cis-Ru(dcbpy)2(NCS)2-sensitized nanostructured TiO2 film ...
