Sensitization of heavy metal free organic dyes onto TiO2 thin films has gained much attention in dye sensitized solar cells (DSSCs). A series of new kojic acid based organic dyes KA1–4 were synthesized via nucleophilic substitution of azobenzene bearing different vinyl chains A1–4 with kojyl chloride 4. Azo dyes KA1–4 were characterized for photophysical properties employing absorption spectrometry and photovoltaic characteristic in TiO2 thin film. The presence of vinyl chain in A1–4 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, KA4 achieved the highest solar to electrical energy conversion efficiency (η = 1.54%) in the series.

Due to their high conversion efficiency and low cost of production, dye-sensitized solar cells based on organic dyes have attracted considerable attention. By utilizing various heterocycles as construction blocks for organic dyes, the performance of solar cells was optimized to exhibit good light-harvesting features and suppress interfacial recombinations. The aim of this review is to highlight recent progress in the molecular design of heterocyclic-functionalized organic dyes for efficient dye-sensitized solar cells, and special attention has been paid to the relationship between chemical structure and the photovoltaic performance of dye-sensitized solar cells based on these dyes.
