Specific interactions of the I-/I3- redox mediators with the reduced and oxidized dye, Ru(4,4'-dicarboxy-2,2'-bipyridyl)2(NCS)2, referred to as N3 or Ru(dcbpy)2(NCS)2, were studied by d. functional theory (DFT) with the focus on the charge transfer process ...
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 ...
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 ...
Org. chromophores were synthesized to study the benefits of structural vs. spectral properties as well as the absorption properties and solar cell performance with an unsym.-substituted chromophore. High Voc was found for the structurally sym. dye which al ...
Nanostructured TiO2 films were modified by insertion with Al ions using an electrochem. process. After heat treatment these films were suitable as electrodes in dye-sensitized solar cells. By a catechol adsorption test and with photoelectron spectroscopy , ...
Photoinduced absorption spectroscopy is presented as a tool for the systematic study of dye regeneration and pore filling in solid state dye-sensitized solar cells. Oxidn. potentials and extinction coeffs. for oxidized species of the perylene dye, ID28, on ...
Dyes with a similar structure, i.e., a combination of triphenylamine with cyanovinylenethiophene, have been synthesized before and have been used in different applications according to Spraul et al., (2004); Roquet et al., (2006); and Hagberg et al., (2006 ...
Nanocryst. TiO2 films, surface modified with Al3+, were manufd. by depositing a TiO2 suspension contg. small amts. of Al nitrate or Al chloride onto conducting glass substrates, followed by drying, compression, and finally heating to 530°. Electrodes prepd ...
The solar to electrical power conversion efficiency for dye-sensitized solar cells (DSCs) incorporating a solid-state organic hole-transporter can be over 5%. However, this is for devices significantly thinner than the optical depth of the active composite ...
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 ...
