| Abstract: Two antenna molecules zinc porphyrin P2, P3 were prepared, and these antenna molecules have been successfully used in DSSCs (dye-sensitized solar cells) through supramolecular self-assembly. Compared with traditional D-π-A structure dyes, this strategy shows obvious advantages. This method can avoid complex synthesis steps, the light-harvesting ability of dyes can be improved and charge recombination can be reduced by adjusting the antenna molecules and anchoring groups. When 4-pyrid-4-ylbenzoic acid (A) was used as the anchoring group, after supramolecular self-assembly, the device of A-P2 displayed a PCE (power conversion efficiency) of 1.68%, and the Voc was 526 mV, the Jsc was 5.39 mA·cm-2. This indicates that the supramolecular self-assembly strategy has been successfully applied in DSSC. The device of A-P3 displayed the PCE of 0.79%, which is mainly due to the lower amount of dye loading. In addition, the optical properties, electrochemical properties, photovoltaic performance were also studied. |
