tailieunhanh - Synthesis and photovoltaic characterization of triarylamine-substituted quinoxaline push–pull dyes to improve the performance of dye-sensitized solar cells

Novel unsymmetrical organic sensitizers having donor, π-spacer, and anchoring groups were designed and synthesized for dye-sensitized solar cell (DSSC) application. The dyes 3-{4-[7-(4-{bis[4-(hexyl)phenyl]amino} phenyl)-11,12-dibutoxy-1,4,5,8-tetrahydrodibenzo [a,c] phenazine-2-yl]phenyl}-2-cyano acrylic acid (KD-148) and 3-{5-[7-(4-{bis[4-(hexyloxy)phenyl]amino} phenyl)-11,12-dibutoxy-1,4,5,8-tetrahydrodibenzo [a,c] phenazine-2-yl]-2-thienyl}-2- cyano acrylic acid (KD-150) were anchored onto TiO2 and tested with ionic liquid electrolyte. |
