Synthesis of Complex compounds Ni(II)-Chlorophyll as dye sensitizer in dye sensitizer solar cell (DSSC)

Increasing global energy demand has resulted in an energy crisis. The dye sensitizer solar cell (DSSC) is an alternative source because of its ability to convert the sun's energy into electrical energy. Our aim was to determine the effect of synthesized Ni(II)-Chlorophyll for enhancing the efficiency of solar cells based DSSC. Complex compound Ni(II)- Chlorophyll was successfully synthesized as a dye sensitizer of Ni(NO₃)₂.6H₂O and chlorophyll ligand with saponification method. Characterization results with spectrophotometer UV-Vis showed that the complex compounds of Ni(II)-Chlorophyll have a maximum wavelength of 295.00 nm, 451.00 and 665.00 nm. The bond between the ligand and metal appears in the vibration Ni-O at wave number 455.2 cm^-1. Complex compoun Ni(II)-Chlorophyll has a magnetic moment 7.10 Bohr Magneton (BM). The performance of complex compound Ni(II)-Chlorophyll as a dye sensitizer shows the value of short-circuit current (Jsc) at 3.00 mA/cm², open circuit voltage (Voc) at 0.15 V and the efficiency (η) 0.20%.
