Both the increasing human population and energy consumption are the main factors which cause energy crises. In this situation, we need new alternative energy source. DSSC (Dye Sensitized Solar Cells) has great potential to develop because the dye as a light catcher can be directly applied in daily life. In this research, Mn(II)-TMPyP complex compound has been synthesized as a dye sensitizer from MnCl 2 .4H 2 O and the derivatives of porphyrin (TMPyP), (5,10,15,20-Tetrakis(1-methyl-4-pyridinio)porphyrin, and tetra(p-toluenesulfonate). Mn(II)-TMPyP complex compound has been characterized using a UV-Vis spectrophotometer and showed a wavelength of 439.50 nm and 461 nm, and the vibration of Mn-N at a wavenumber of 300.90 cm −1 . The performance of Mn(II)-TMPyP complex compound as photosensitizer respectively obtained the value of shortcircuit current (Jsc) at 5 mA/cm 2 , with an open circuit voltage (Voc) at 0.40 V and the value of efficiency at 3.64%.
