Studies from School of Basic Science Provide New Data on Thin Solid Films

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Thin Solid Films is now available. According to news reporting out of Lausanne, Switzerland, by VerticalNews editors, research stated, "We report the design, synthesis and computational investigation of a class of Ru(II)-dyes based on mixed bipyridine ligands for use in dye-sensitized solar cells. These dyes are designed to preserve the optimal anchoring mode of the prototypical N719 sensitizer by three carboxylic groups, yet allowing for tunable optimization of their electronic and optical properties by selective substitution at one of the 4-4' positions of a single bipyridine ligand with pi-excessive heteroaromatic groups."

Our news journalists obtained a quote from the research from the School of Basic Science, "We used Density Functional Theory/Time Dependent Density Functional Theory calculations to analyze the electronic structure and optical properties of the dye and to investigate the dye adsorption mode on a TiO2 nanoparticle model. Our results show that we are effectively able to introduce three carboxylic anchoring units into the dye and achieve at the same time an enhanced dye light harvesting, demonstrating the design concept."

According to the news editors, the research concluded: "As a drawback of this type of dyes, the synthesis leads to a mixture of dye isomers, which are rather tedious to separate."
