High efficient triphenylamine based mono and di branched organic sensitizers in dye-sensitized solar cells |
초록 |
A series of single and double branched organic dyes (1–4) utilizing two different acceptor groups, cyanoacetic acid and rhodanine acetic acid as anchoring moieties were synthesized and characterized for dye sensitized solar cells (DSSCs). The DSSC based on 3 has the best power conversion efficiency (3.51%) among all devices, which is 2 times higher than that of 1 with only one anchoring group. Compared with the 1-2 congeners with only one anchor, the dianchoring dyes 3-4 can more effectively suppress charge recombination and increase electron injection efficiency, leading to higher open-circuit voltage and short-circuit current |
