제목 Novel D-π-A Structured Zn(II)-porphyrin Dyes Containing Bis-dimethylfluorenylamine Moeity for Dye-Sensitized Solar Cells.
초록 Two kind of novel D-π-A Zn(II)-porphyrin dyes containing bis-dimethylfluorenylamine moiety were developed for use in dye-sensitised solar cells (DSSCs). Either carboxylic acid or cyano-acrylic acid moiety linked via phenylene π-conjugated bridge system was also introduced as the electron acceptor at the opposite meso-position. 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 have been used to fabricate dye-sensitized solar cells based on liquid electrolytes and high energy conversion efficiency of 7.22 % has been achieved with short circuit current (Jsc) of 15.303 mA/cm2, open circuit voltage (Voc) of 669 mV and fill factor (FF) of 0.706 for 2Flu-ZnP-CN-COOH dye when co-adsorbed with HC-A1 co-adsorbent which previously developed by our group under standard global AM 1.5 solar irradiation.
