Comparison of performance between benzoindoline and indoline dyes in zinc oxide dye-sensitized solar cell

The cell performance of novel benzoindoline dyes on zinc oxide prepared by template cathode electro-deposition method was compared with that of known indoline dyes. Among cyanoacrylic, single and double rhodanine acetic acid derivatives, the cyanoacrylic benzoindoline dye showed better performance than the indoline dye (D131) due to larger Jsc value which comes from its positive Eox level and bathochromic UV–vis absorption band.
