Journal ArticleDOI

Synthesis, characterization, and DFT-TDDFT computational study of a ruthenium complex containing a functionalized tetradentate ligand

TL;DR: From the analysis of the computed optical transitions of N886, its absorption bands are assigned as mixed Ru/SCN-to-quaterpyridine charge-transfer transitions, which extend from the near-IR to the UV regions.
Journal ArticleDOI

Regeneration and recombination kinetics in cobalt polypyridine based dye-sensitized solar cells, explained using Marcus theory

TL;DR: Regeneration and recombination kinetics was investigated for dye-sensitized solar cells (DSCs) using a series of different cobalt polypyridine redox couples, with redox potentials ranging between 0.34 and 1.20 V vs. NHE.
Journal ArticleDOI

High-Performance Liquid and Solid Dye-Sensitized Solar Cells Based on a Novel Metal-Free Organic Sensitizer

TL;DR: In this article, a metal-free organic sensitizer for dye-sensitized solar cells is presented, in combination with a solvent-free ionic liquid electrolyte, which shows excellent stability measured under thermal and light-soaking dual stress.
Journal ArticleDOI

Light Induced Redox Reactions of Water Soluble Porphyrins, sensitization of hydrogen generation from water by zincporphyrin derivatives

TL;DR: The photoredox behavior of two water soluble derivatives of zincporphyrin, 5,10,15,20-tetra-p-sulfonatophenyl (1) and 5, 10, 15, 20-TTE-N-methylpyridiniochloride (2), was investigated using laser and continuous photolysis techniques.
