We have designed and synthesized novel D-π-A zinc porphyrin dyes as the most efficient green dye for DSSCs application. They contain long alkoxy substituted electron-donating group and a meso-substituted phenyl cyanoacrylic acid attached at the meso position of the porphyrin ring. These porphyrins were designed to disturb dye aggregation and charge recombination by wrapping the porphyrin dye with long alkoxy chain in the ortho position of each meso-phenyl ring and donor. These Zn(II)-porphyrin dyes have been used to fabricate dye-sensitized solar cells based on liquid electrolytes. Here, their synthesis, characterization and DSSC performance will be described. |
