N-Annulated perylene as a donor in cyclopentadithiophene based sensitizers: the effect of the linking mode†
Two types of cyclopentadithiophene dyes with different linking modes with an N-annulated perylene (NP) donor were designed and synthesized. These new dyes were applied in Co(II)/(III) based dye-sensitized solar cells and an efficiency up to 7.8% could be obtained for peri-NP linked CPD-1. The effect of the linking mode on the material properties and device performance was discussed.
