Heterovalent, Homometallic Rings: Synthesis, Optical, and EPR Studies of {TiIV7TiIII} Complexes

Chemistry – A European Journal, EarlyView.
A new class of heterovalent, homometallic complexes is reported, based on cyclic {TiIV7TiIII} cores with oxide and carboxylate bridges between nearest neighbors. The clusters show Class II mixed‐valent behavior at room temperature, but are valence localized at low temperature.

Carbonaceous Dye‐Sensitized Solar Cell Photoelectrodes [PDF]

Advanced Science, 2015
High photovoltaic efficiency is one of the most important keys to the commercialization of dye sensitized solar cells (DSSCs) in the quickly growing renewable electricity generation market. The heart of the DSSC system is a wide bandgap semiconductor based photoelectrode film that helps to adsorb dye molecules and transport the injected electrons away ...

Green Chemistry im Chemieunterricht: eine farbstoffsensibilisierte Solarzelle mit sicheren und leicht verfügbaren Materialien

CHEMKON, EarlyView.
Farbstoffsensibilisierte Solarzellen (Dye‐sensitized Solar Cells, DSSCs) stellen einen biomimetischen Ansatz zur Umwandlung von Sonnenlicht in elektrische Energie dar, der sich am Funktionsprinzip der Photosynthese orientiert. Trotz ihres seit den frühen 1990er‐Jahren bekannten Konzepts existieren bislang nur wenige experimentelle Zugänge, die zugleich

A Convenient Method for Manufacturing TiO2 Electrodes on Titanium Substrates

International Journal of Photoenergy, 2011
Thin titanium dioxide films were successfully prepared on titanium plates in ammonium sulfate solution with the micro-plasma oxidation method. The thin TiO2 films were sensitized with a cis-RuL2(SCN)2⋅2H2O (L = cis-2, 2′-bipyridine-4, 4′-dicarboxlic acid)

Buried Interface Engineering via a Bifunctional Guanidino‐Carboxyl Molecular Bridge for Enhanced Performance and Stability in Perovskite Solar Cells

EcoEnergy, EarlyView.
A bifunctional molecular bridge using 4‐guanidinobutanoic acid (GCC) is constructed to comprehensively tailor the buried interface of PSCs. By passivating oxygen vacancies, optimizing energy‐level matching, and regulating perovskite crystallization, this strategy simultaneously boosts the power conversion efficiency to 25.37% (20.01% for 13.4 cm2) and ...
