초록

In the present study, deprotonation of curcumin dye using potassium carbonate was performed successfully, which produced fairly stable deprotonated dye with a large bathochromic shift in the visible light absorption spectrum. The light-harvesting efficiency of this deprotonated dye was investigated in TiO2-based dye sensitized solar cells, which exhibited an energy conversion efficiency of 0.91%, and this value is 8.3 times higher than that of the dye sensitized solar cells with curcumin photosensitizer without deprotonation.
