Iridium (III) complexes with 5,5-dimethyl-3-(pyridin-2-yl)cyclohex-2-enone ligands as sensitizer for dye-sensitized solar cells

- Iridium complexes with 5,5-dimethyl-3-(pyridine-2-yl)cyclohex-2-enone were synthesized.
- The absorption response to low energy band was extended and the emission of deep red was realized.
- A wide spectral range (350-675 nm) and open-circuit voltage of 645 mV was presented using for DSSC.
