Solvent Effects on the Adsorption Geometry and Electronic Structure of Dye-Sensitized TiO2: A First-Principles Investigation [PDF]

, 2012
The performance of dye-sensitized solar cells (DSSCs) depends significantly on the adsorption geometry of the dye on the semiconductor surface. In turn, the stability and geometry of the adsorbed molecules is influenced by the chemical environment at the

Influence of Dye Adsorbtion Time on TiO2 Dye-Sensitized Solar Cell with Krokot Extract (Portulaca Oleracea. L) as A Natural Sensitizer [PDF]

Journal of Pure and Applied Chemistry Research, 2015
Dye sensitized solar cells (DSSC) photoelectrodes were fabricated using titanium oxide (TiO2) and sensitized with the krokot extract dye. This study investigated the effect of dye adsorption time to an efficiency of the solar cells. The fabrication cells

Interfacial Enrichment and Demetallation of a Zinc Porphyrin in the Ionic Liquid [C4C1Im][PF6]

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Upon dissolution of zinc porphyrins with long dodecyl chains in the ionic liquid [C4C1Im][PF6], partial [PF6]‐ hydrolysis occurs along spontaneous porphyrin demetallation. Driven by their buoy‐like chains, the free‐base porphyrins extremely enrich at the outermost surface as proven by angle‐resolved X‐ray photoelectron spectroscopy, an interesting ...

Unveiling the Photophysical Properties of Indole‐Containing Boron Complexes: Exploring Intramolecular Charge Transfer Character, Tunable Emission, and Large Stokes Shifts

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Indolyl‐imine–based NN complexes were synthesized and investigated to clarify how structural modification tunes intramolecular charge transfer (ICT), resulting in large Stokes shifts and tunable emission properties. Steady‐state and ultrafast spectroscopy, supported by density‐functional theory (DFT), showed that altering peripheral phenyl groups ...
