Journal ArticleDOI
Visible Light Water Splitting Using Dye-Sensitized Oxide Semiconductors
TL;DR: The approach to two problems in solar water splitting are described: the organization of molecules into assemblies that promote long-lived charge separation, and catalysis of the electrolysis reactions, in particular the four-electron oxidation of water.
Journal ArticleDOI
Photoassisted Overall Water Splitting in a Visible Light-Absorbing Dye-Sensitized Photoelectrochemical Cell
Justin W. Youngblood,Seung Hyun Anna Lee,Yoji Kobayashi,Emil A. Hernández-Pagán,Paul G. Hoertz,Thomas A. Moore,Ana L. Moore,Devens Gust,Thomas E. Mallouk +8 more
TL;DR: Iridium oxide nanoparticles stabilized by a heteroleptic ruthenium tris(bipyridyl) dye were used as sensitizers in photoelectrochemical cells consisting of a nanocrystalline anatase anode and a Pt cathode to measure the rates of forward and back electron transfer.
Journal ArticleDOI
Coupling of Titania Inverse Opals to Nanocrystalline Titania Layers in Dye-Sensitized Solar Cells†
Seung Hyun Anna Lee,Neal M. Abrams,Paul G. Hoertz,Greg D. Barber,Lara I. Halaoui,Thomas E. Mallouk +5 more
TL;DR: A quantitative comparison of the photoaction spectra, short circuit current densities, and power conversion efficiencies of dye-sensitized solar cells (DSSCs) that contain bilayers of nanocrystalline TiO2 and titania inverse opal photonic crystals (PCs) supports a model proposed by Miguez and co-workers.
Journal ArticleDOI
Photocatalytic Hydrogen Evolution from Hexaniobate Nanoscrolls and Calcium Niobate Nanosheets Sensitized by Ruthenium(II) Bipyridyl Complexes
Kazuhiko Maeda,Miharu Eguchi,Seung Hyun Anna Lee,W. Justin Youngblood,Hideo Hata,Thomas E. Mallouk +5 more
TL;DR: In this article, the authors compared oxide semiconductors in photocatalytic assemblies for H2 production using ethylenediaminetetraacetic acid (EDTA) as a sacrificial electron donor and platinum (Pt) nanoparticles as catalysts.
Journal ArticleDOI
Electron transfer kinetics in water splitting dye-sensitized solar cells based on core–shell oxide electrodes
Seung Hyun Anna Lee,Yixin Zhao,Emil A. Hernández-Pagán,Landy K. Blasdel,W. Justin Youngblood,Thomas E. Mallouk +5 more
TL;DR: The factors that lead to polarization of the photoanode and possible ways to re-design the system for higher efficiency are discussed.
