Brief on Features and Applications of Solvent Dyes, and The Chemistry of Pigments

The selection of solvent for preparing a working electrode (and to act as the electrolyte) is known to influence the

efficiency of dye-sensitized solar cells. In this topical review, results taken from a systematic study are presented from

the authors’ own lab examining how protic and aprotic solvents, as well as solvent polarity, affect adsorption of carboxylic

dyes on the titanium dioxide nanoparticle surface and electron injection from the dye to the semiconductor. Adsorption of dye

molecules on nanoparticle surfaces is measured through second harmonic light scattering and electron injection through

ultrafast transient mid-infrared absorptio
