Green Light Harvester by Porphyrin Derivative Complexes: The Influence of Metal in Photovoltaic on Dye-Sensitized Solar Cells

The high demand for renewable energy makes a light harvester material (dye sensitizer) interesting to be developed by scientists. This research has been synthesized a series of material dye sensitizer based on derivatives of porphyrin and successfully investigated the influence of metals in photovoltaic performance. The derivatives of porphyrin used are TMPyP (5,10,15,20-tetrakis(1-methyl-4-pyridinio) tetra porphyrin (p-toluenesulfonate)) reacted by metal ions Fe(II), Co(II), Ni(II) and Cu(II). The larger atomic number of metals, the higher effective nuclear charge of the metal, resulting better photovoltaic performance. The highest performance of solar cell reached efficiency 4.65 %.
