Incorporation of Kojic Acid-Azo Dyes on TiO2 Thin Films for Dye Sensitized Solar Cells Applications

Sensitization of heavy metal free organic dyes onto TiO2 thin films has gainedmuch attention in dye sensitized solar cells (DSSCs). A series of new kojic acid based organic dyes KA�–� were synthesized via nucleophilic substitution of azobenzene bearing different vinyl chains A�–� with kojyl chlori...
