Two triphenylamine based dyes (XS19 and XS22) containing N,N-dimethylaniline unit as secondary electron-donating groups with different conjugated lengths were synthesized and characterized with regard to their photophysical and photoelectrochemical properties. The dyes were applied into nanocrystalline TiO2 dye-sensitized solar cells through standard operations. It was found that, introduction of N,N-dimethylaniline unit suppressed dye aggregation and brought about superior performance over the simple triphenylamine dye in terms of power conversion efficiency. For a typical device (based on XS22) a maximum power conversion efficiency of 4.7% was obtained under simulated AM1.5 irradiation (100 mW• cm-2) with JSC=9.6 mA•cm-2, VOC=685 mV and FF=0.72.
