Novel Organic Dyes Based on Bulky Tri(triphenylamine)-Substituted Styrene for Dye-Sensitized Solar Cells

• Three novel donor-p-acceptor (D-p-A) metal-free organic dyes (TB, TS and TF) based on tri(triphenylamine)-substituted styrene as donor with various conjugated linkers (benzene, thiophene and furan) were synthesized, characterized and used for the application of dye-sensitized solar cells (DSSCs). Under the same condition, The photo-to-electrical conversion efficiency of the DSSCs sensitized with TB, TS and TF reach 1.84%, 4.10% and 4.52%, respectively, which are lower than that sensitized with R1 (5.02%) with one triphenylamine unit. The results suggest that these bulky donor-based sensitizers are unfavorable to DSSCs.
