Journal ArticleDOI
Parameters Influencing Charge Separation in Solid-State Dye-Sensitized Solar Cells Using Novel Hole Conductors
Jessica E. Kroeze,Jessica E. Kroeze,Narukuni Hirata,Lukas Schmidt-Mende,Lukas Schmidt-Mende,Charles Orizu,Simon Dominic Ogier,Kathryn Carr,Michael Grätzel,James R. Durrant +9 more
TL;DR: In this article, a series of novel triarylamine type oligomers, varying in molecular weight and mobility, are studied to determine hole-transfer yields and pore-penetration characteristics.
Journal ArticleDOI
Correlating long-lived photogenerated hole populations with photocurrent densities in hematite water oxidation photoanodes
Stephanie R. Pendlebury,Alexander J. Cowan,Monica Barroso,Kevin Sivula,Jinhua Ye,Michael Grätzel,David R. Klug,Junwang Tang,James R. Durrant +8 more
TL;DR: In this article, the authors investigated the photogenerated charge carrier dynamics as a function of applied bias in a variety of different hematite photoanodes for solar water oxidation, and reported a general quantitative correlation between the population of long-lived holes and the photocurrent amplitude.
Journal ArticleDOI
Photovoltaic performance and long-term stability of dye-sensitized meosocopic solar cells
TL;DR: Gratzel et al. as discussed by the authors analyzed the kinetic requirements for dye-sensitized mesoscopic photovoltaic cells to achieve a service life of at least 20 years under normal outdoor conditions.
Journal ArticleDOI
Molecular Design of Unsymmetrical Squaraine Dyes for High Efficiency Conversion of Low Energy Photons into Electrons Using TiO2 Nanocrystalline Films
Thomas Geiger,Simon Kuster,Jun-Ho Yum,Soo-Jin Moon,Mohammad Khaja Nazeeruddin,Michael Grätzel,Frank Nüesch +6 more
TL;DR: In this article, an optimized unsymmetrical squaraine dye with carboxylic acid as anchoring group is synthesized for dye-sensitized solar cells (DSCs).
Journal ArticleDOI
Ambient temperature plastic crystal electrolyte for efficient, all-solid-state dye-sensitized solar cell.
TL;DR: Doping the molecular plastic crystal of succinonitrile with solid N-methyl-N-butylpyrrolidinium iodide salt and iodine has produced a highly conductive solid iodide/triiodide conductor that was employed for a highly efficient, all-solid-state dye-sensitized solar cell.
