Abstract

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 chloride �. Azo dyes KA�–� were characterized for photophysical properties employing absorption spectrometry and photovoltaic characteristic in TiO2 thin film. The presence of vinyl chain in A�–� improved the photovoltaic performance from 0.20 to 0.60%. The introduction of kojic acid obtained from sago waste further increases the efficiency to 0.82–1.54%. Based on photovoltaic performance, KA� achieved the highest solar to electrical energy conversion efficiency (
