Origin of the kinetic heterogeneity of ultrafast light-induced electron transfer from Ru(II)-complex dyes to nanocrystalline semiconducting particles
TL;DR: In this article, it was shown that dye aggregation at the interface is actually responsible for the slow kinetic component of the interfacial electron transfer, and a thorough control of the dissolution of the dye and of its adsorption onto nanocrystalline oxide films allowed the reduction of the portion of dye excited states that react within the slow compartment and even made the latter completely disappear.
Journal ArticleDOI
Ca2+-sensitive monolayer electrodes
TL;DR: A Ca2+ sensor based on the admittance change of synthetic membranes supported on derivatized silicon electrodes is reported in this paper, where the ion-sensitive membranes consist of mixed monolayers of phospholipid and the Ca2-ligand ETH 1001.

TL;DR: In this article, a type organic dyes with a coplanar dithieno[2,3d;2′,3′-d′]benzo[1,2 b;4,5-b′]dithiophene (DTBDT) was used as π-spacer for dye-sensitized solar cells.
Journal ArticleDOI
Investigation of Interfacial Charge Separation at PbS QDs/(001) TiO2 Nanosheets Heterojunction Solar Cell
TL;DR: In this article, the kinetics of interfacial charge separation of PbS QDs/(001) TiO2 nanosheets heterojunction solar cells were investigated using the ultrafast pump-probe laser spectroscopy technique.
Journal ArticleDOI
Low Cost and Efficient Photovoltaic Conversion by Nanocrystalline Solar Cells
TL;DR: In this paper, a molecular photovoltaic device based on the sensitization of nanocrystalline oxide films by transition metal charge transfer sensitizers has been developed, achieving an overall efficiency of 10% for AM 1.5 solar light to electricity.
