Four novel D-D-π-A configuration metal-free organic dyes (C3, P2, C2 and P3) with triphenylethylene phenothiazine moieties or triphenylethylene carbazole moieties as additional electron donors for dye-sensitized solar cells (DSSCs) have been synthesized. The cells based on C3, P2, C2 and P3 dyes with efficiencies of 2.14%, 2.69%, 5.51% and 6.55%, respectively, are obtained. The P3 based cell exhibits the highest efficiency of 6.55% accompanied by a short-circuit current density (Jsc) of 12.18 mA cm-2, a rather high open-circuit photovoltage (Voc) of 826 mV, and a fill factor (ff) of 0.65, performances which are remarkable in the DSSCs based on metal-free organic dyes. The twisted non-planar configuration in P3 decelerates the charge recombination in the charge-separated state and hence contributes to the improvement of the performance of DSSCs.

New piezofluorochromic compounds with high thermal stabilities and aggregation-induced emission behavior were developed. The spectroscopic properties and morphological structures of these compounds were reversed upon pressing (or grinding)/annealing (or fuming). The switchable color change feature and aggregation-induced emission make the compounds promising candidates for optical recording, pressure-sensing, and light-emitting systems.
