Journal ArticleDOI
Conversion of light to electricity by cis-X2bis(2,2'-bipyridyl-4,4'-dicarboxylate)ruthenium(II) charge-transfer sensitizers (X = Cl-, Br-, I-, CN-, and SCN-) on nanocrystalline titanium dioxide electrodes
Mohammad Khaja Nazeeruddin,Andreas Kay,I. Rodicio,Robin Humphry-Baker,E. Mueller,Paul Liska,Nick Vlachopoulos,Michael Graetzel +7 more
TL;DR: Cis-X 2 Bis(2,2'-bipyridyl-4,4'-dicarboxylate)ruthenium(II) complexes were prepared and characterized with respct to their absorption, luminescence, and redox behavior.
Journal ArticleDOI
New Benchmark for Water Photooxidation by Nanostructured α-Fe2O3 Films
TL;DR: In this article, thin films of silicon-doped Fe2O3 were deposited by APCVD (atmospheric pressure chemical vapor deposition) from Fe(CO)5 and TEOS (tetraethoxysilane) on SnO2-coated glass at 415 °C.
Journal ArticleDOI
Low cost photovoltaic modules based on dye sensitized nanocrystalline titanium dioxide and carbon powder
Andreas Kay,Michael Grätzel +1 more
TL;DR: In this article, a new type of photovoltaic module based on monolithically series connected dye-sensitized photoelectrochemical cells is described, where each solar cell element consists of three porous layers on a transparent conducting substrate.
Journal ArticleDOI
Artificial photosynthesis. 1. Photosensitization of titania solar cells with chlorophyll derivatives and related natural porphyrins
Andreas Kay,Michael Graetzel +1 more
TL;DR: In this article, Colloidal TiO[sub 2] electrodes were photosensitized with derivatives of chlorophyll and related natural porphyrins resulting in light harvesting and charge separation efficiencies comparable to those in natural photosynthesis.
Journal ArticleDOI
Translucent thin film Fe2O3 photoanodes for efficient water splitting by sunlight: nanostructure-directing effect of Si-doping.
TL;DR: The morphology of the alpha-Fe2O3 was strongly influenced by the silicon doping, decreasing the feature size of the mesoscopic film, and the best performing photoanode would yield a solar-to-chemical conversion efficiency of 2.1% in a tandem device using two dye-sensitized solar cells in series.
