Novel porphyrin sensitizers had been designed and synthesized by the new synthetic method and characterized by various spectroscopic techniques to explore in dye-sensitized solar cells (DSSCs). The long wavelength absorbing porphyrin sensitizers were characterized by the cyclic voltammetry for electrochemical properties. The absorption character of synthesized porphyrin on the photo-electrode was different with that of solution state which made totally different IPCE spectrum in DSSCs. We tried to estimate and understand the difference between absorption property of porphyrin on the photo-electrode and IPCE characteristics in DSSC.
