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