Increasing energy demands and concerns over global warming have led to a greater focus on dye-sensitized solar cell (DSSCs) in recent years. Herein, we synthesized the metal-free organic sensitizer YY1 with optimal molecular design. In this dye, diphenylamino group acts as a donor, whereas 2-cyanoacetic acid acts as an acceptor and anchoring group to TiO2, and bridged by low-band-gap π-conjugated chromophore. The diindenothiophene chromophore leads to an efficient intramolecular charge separation within such system. Furthermore, the existence of alkoxyaryl groups on the sp3 carbon is expected to suppress molecular stacking of dye on TiO2. And the hydrophobic chains prevent the approach of electrolyte toward TiO2 surface and consequently reduce charge recombination. The photovoltaic performances of the DSSC under standard AM 1.5 irradiation, shown as follow:
