Synthesis and Performance of Organic Photo-Sensitizers Containing Multi-Acceptors/Anchors for the Application of Dye-Sensitized Solar Cells |
| 초록 |
Organic photo-sensitizers containing multi-acceptors in a chromophore have been synthesized and characterized for the application of dye-sensitized solar cell (DSSC). In this study, we have used intramolecular push-pull system containing phenothiazine as the electron donor with different number of cyanoacetic acid moieties as electron acceptor/anchoring groups in a chromophore. The experimental results have revealed that when the induced electron acceptor increases, the larger amounts of dyes are adsorbed on the TiO2 surface in DSSC, resulting in the increase of short circuit photocurrent density. Our results suggest that the organic dyes with multi-electron acceptors moieties are promising for getting higher solar-to electricity conversion efficiencies in DSSC. |
