Journal ArticleDOI
Cyclometalated iridium(III) complexes based on phenyl-imidazole ligand.
Etienne Baranoff,Simona Fantacci,Filippo De Angelis,Xianxi Zhang,Rosario Scopelliti,Michael Grätzel,Khaja Nazeeruddin +6 more
TL;DR: These series show that modifying the substitution pattern on the ligands can alter the photophysical and electrochemical properties of the complexes, and it is shown that compared to complexes containing phenyl-pyridine ligands, highest occupied molecular orbitals (HOMOs) and lowest unoccupied molecular Orbitals (LUMOs) are more delocalized over the entire main ligand in complexes containing Phenyl-imidazole.
Journal ArticleDOI
Molecular Engineering of Zinc Phthalocyanines with Phosphinic Acid Anchoring Groups
Ismael López-Duarte,Mingkui Wang,Mingkui Wang,Robin Humphry-Baker,Mine Ince,M. Victoria Martínez-Díaz,Mohammad Khaja Nazeeruddin,Tomás Torres,Michael Grätzel +8 more
TL;DR: This poster presents a probabilistic procedure to characterize the phthalocyanine-like properties of Tio2 Films and its application in solar cells and its applications in photovoltaic cells.
Journal ArticleDOI
Electron injection kinetics for the nanocrystalline TiO2 films sensitised with the dye (Bu4N)2Ru(dcbpyH)2(NCS)2
TL;DR: In this paper, transient absorption spectroscopy is employed to determine the electron injection kinetics for nanocrystalline TiO2 electrodes sensitised with the dye (Bu4N)2Ru(dcbpyH)2(NCS)2 2.
Journal ArticleDOI
Fine-tuning the Electronic Structure of Organic Dyes for Dye-Sensitized Solar Cells
TL;DR: The sensitizer containing the thiophene and CPDT showed the most broad incident photon-to-current conversion efficiency spectra, resulting in a solar energy conversion efficiency of 6.6%.
Journal ArticleDOI
Photoelectrochemistry with Colloidal Semiconductors; Laser Studies of Halide Oxidation in Colloidal Dispersions of TiO2 and α-Fe2O3
Jacques Moser,Michael Grätzel +1 more
TL;DR: Aqueous sols of TiO2 (anatase, particle radius 25 A) were excited with (347.1 nm)-laser light and the reaction of valence-band holes with halide ions (X = I−, Br−, Cl−) was investigated as discussed by the authors.
