Novel D-π-A Zn(II)-porphyrin dyes containing thiophene moiety at meso-position were developed for use in dye-sensitised solar cells (DSSCs). Their chemical structures were characterized by 1H-NMR, FT-IR, UV-vis absorption and MALDI-TOF mass spectroscopy. Their electrochemical properties were also studied by cyclic voltammetry measurement. These novel Zn(II)-porphyrin dyes with the HC adsorbents have been used to fabricate dye-sensitized solar cells based on liquid electrolytes. The high energy conversion efficiency of 6.7 % has been achieved with HC adsorbents under standard global AM 1.5 solar irradiation.. |
