Compared to those cells based on the dyesSDD4andRD, the
relatively lower photovoltaic performance of double DeAdyes
SDD1e3-sensitized cells was due to their relatively lower shortcircuit photocurrent density (Jsc), which could be ascribed to the
donor of indole with weak and narrow light-harvesting ability in
The higher Jsc may be attributed to
the relatively bigger dye loading on the TiO2 surface, and the higher Voc may be ascribed to then-hexyl, which hinders the dye SDD3 aggregation on TiO2more effectively. Furthermore, the cell based
onSDD1exhibited lower h due to its lower dye loading amount, which resulted from the rigid and large linker of 1,4-phenylenebis(methylene).
