Dye-sensitized solar cells based on organic photosensitizers featuring a thienylethynyl spacer |
| 초록 |
In this presentation, we report the facile synthesis of metal-free organic photosensitizers (CSD-01 and CSD-02) featuring a thienylethynyl spacer in two steps from commercially available materials and their application to dye-sensitized solar cells (DSSCs). Our studies reveal that the additional thiophene bridge unit allows for the decrease in the bandgap of the organic photosensitizer and better photovoltaic performance of the DSSCs. We also investigate the effect of dye adsorption conditions including concentration and co-additives and different redox pairs including iodide/iodine and Co(II)/Co(III) on DSSC performance. |
