Abstract
The energy crisis is a major problem facing the world today and will need a renewable energy source that is environmentally friendly; one of these is the dye sensitized solar cell (DSSC). DSSC is photochemical electric cell that can convert solar energy into electrical energy. This research aims to study the characteristics of chlorophyll compounds with the addition of metal ions Fe(III) and to determine the effect of Fe(III) on the performance of chlorophyll as a photosensitizer in the DSSC. The formation of complex compounds of Fe(III)-chlorophyll is shown by the phenomenon of metal ligand charge transfer (MLCT) at a wavelength of 263.00 nm and absorption transition d-d at 745.00 nm. Fourier transform infrared characterization of the binding of Fe-O complex compounds appears at 486.06 cm−1. The complex compound of Fe(III)-chlorophyll has a magnetic moment value of 9.62 Bohr Magneton (BM). The existence of ion Fe(III) in chlorophyll can improve the performance of chlorophyll as a dye sensitizer with a maximum current of 4.00 mA/cm2, maximum voltage of 0.18 volts and efficiency values of 1.35%.
