Eleven novel donor acceptor π-conjugated (D-π-A) org. dyes were engineered and synthesized as sensitizers for the application in dye-sensitized solar cells (DSSCs). The electron-donating moieties are substituted tetrahydroquinoline, and the electron-withdr ...
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 review of the research and development of dye-sensitized solar cells within the Swedish research program Angstrom Solar Center. A path towards low prodn. cost is the development of a continuous process, which allows the prodn. of solar cells in large vol ...
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 ...
The interaction between the dye cis-bis(4,4'-dicarboxy-2,2'-bipyridine)-bis(isothiocyanato) ruthenium(II), Ru(dcbpyH2)2(NCS)2, and nanostructured ZnO was investigated by photoelectron spectroscopy (PES) using synchrotron radiation. The results are compared ...
By deliberately causing degrdn. of components in a dye-sensitized solar cell the authors have studied failure mechanisms of such cells. The dye, bis(tetrabutylammonium) cis-bis(thiocyanato)bis(2,2'-bipyridine-4-carboxylic acid, 4'-carboxylate)ruthenium(II) ...
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 series of new hybrid organic-inorganic molecules were prepared either by grafting of aminopropyltriethoxysilane (APTS) on silica nanoparticles followed by quaternarization of the nitrogen with ethyl, heptyl and isopropyl iodides or by grafting of N,N,N-t ...
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 ...
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 ...
