Performance of complex compound Zn-TPP (5,10,15,20-tetrafenylporphyrin) as a dye sensitizer in increasing the current and voltage of dye sensitized solar cells

Abstract

Solar cell technology has been widely used, one of them is Dye Sensitized Solar Cell (DSSC), which is a semiconductor device that can convert sunlight into electrical energy. The objective of this research is to learn the character of metal complexes from derivatives porphyrin Zn-TPP (5,10,15,20-tetraphenylporphyrin) and apply it as a dye sensitizer in DSSC. Zn(II)-TPP complex compound showed a maximum wavelength at 423 nm on the Soret band. Zn-N bond formed between metal and ligand is indicated at 324,04 cm-1. Zn (II)-TPP complex compound is ionic and best used in DSSC applications. The performance (efficiency) of Zn (II)-TPP complex as dye sensitizer in DSSC shows a maximum current of 8 mA/cm2 with a maximum voltage of 0.60 V and an efficiency value of 9.43%.
