Abstract
Porphyrins, an organic molecule, are a possible sensitizer for dye-sensitized solar cells (DSSC) because of their strong absorption in the visible spectrum. One naturally occurring porphyrin is protoporphyrin IX (PPIX), which can be found in brown eggshells. There are two reasons why PPIX is the ideal sensitizer. (1) The absorbance spectrum of PPIX can be modified by changing ring substituents, thus tuning the absorbance to the solar spectrum. (2) PPIX allows for direct attachment to the DSSC due to the carboxylic acid substituents on PPIX and the TiO2 of the DSSC. The HPLC was used to develop a chromatographic method for PPIX purification, then that method was applied to FPLC. The waste and sample were collected and evaluated for concentrations levels of PPIX.
