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

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

Dye Sensitized Solar Cell, DSSC

Songklanakarin Journal of Science and Technology (SJST), 2003
A dye sensitized solar cell is a new type of solar cell. The operating system of this solar cell type is similar to plant’s photosynthesis process. The sensitizer is available for absorption light and transfer electrons to nanocrystalline metal oxide semiconductor. The ruthenium(II) complexes with polypyridyl ligands are usually used as the sensitizers
