Illumination Time Dependent Learning in Dye Sensitized Solar Cells
Hoi Nok Tsao,Michael Grätzel +1 more
TL;DR: A dye-sensitized solar cell is proposed that learns using illumination time as a cue, potentially enabling visually learning electronics operating at negligible energy consumption and minimal hardware complexity.
Journal ArticleDOI

Journal ArticleDOI
Ground- and excited-state properties of some ligand-bridged ruthenium(II) polypyridyl complexes with spectator-ligand-based emission
TL;DR: In this paper, the lowest excited state of the ligand-bridged polypyridyl complexes [Ru(biq)2}2(dpp)]4+ and [(bipy)2Ru(d pp)Ru(Biq) 2]4+] is assigned to that of the charge-transfer type involving the spectator ligand biq.

Ultrafast charge transfer through p-oligo(phenylene) bridges: effect of nonequilibrium vibrations
Christophe Bauer,Joël Teuscher,Serge Pelet,Bernard Wenger,Pierre Bonhote,Mohammad Khaja Nazeeruddin,Shaik M. Zakeeruddin,Pascal Comte,Michael Grätzel,Jacques-Edouard Moser +9 more
TL;DR: The back and the forward electron transfer rates have been measured by femtosecond and nanosecond spectroscopy in a heterogeneous donor-bridge-acceptor system and it is confirmed that the damping factor is not only linked to the nature of the molecular bridge but to the full D-B-A system.
