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 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 ...
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 ...
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 ...
Dinuclear class II CoIII/FeII mixed-valence complexes, [LnCoIII(μ-NC)FeII(CN)3L2]m-, where Ln represents a pentadentate macrocycle and L2 a bpy ligand or 2 cyanides, have electronic properties that make them possible sensitizers in dye sensitized solar cel ...
The electron transport and recombination in dye-sensitized TiO2 solar cells with different electrolytes have been investigated. The electrolytes were based on iodine-doped ionic liqs. (diethylmethylsulfonium iodide, dibutylmethylsulfonium iodide or 3-hexyl ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
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 ...
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 ...
The main features of the characteristic impedance spectra of dye-sensitized solar cells are described in a wide range of potential conditions: from open to short circuit. An equivalent circuit model was proposed to describe the parameters of electron trans ...
