Organic Photo-Sensitizers of synthesized base on Multi-acceptor in a chromophore for Dye-Sensitized Solar Cells |
| 초록 |
Since Grätzel et al. reported the first efficient dye-sensitized solar cells (DSSCs) in 1991, which have attracted much attention due to their relatively high power conversion efficiency and potentially low cost production. 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 the 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. |
