Donor–acceptor type organic dyes (TA-EDOT-CA and TA-DM-EDOT-CA) containing thiophenevinylene spacer with 3,4-ethylenedioxythiophene (EDOT) substituent were synthesized and characterized for dye-sensitized solar cells (DSSCs). TA-EDOT-CA and TA-DM-EDOT-CA showed 26700 and 28000 M−1·cm−1 of molar absorption coefficient at 458 nm and 459 nm of UV/vis absorption maximum wavelength, respectively. The overall solar-to-energy conversion efficiency of TA-EDOT-CA and TA-DM-EDOT-CA was 8.26% and 7.23% under AM 1.5 illumination (100 mW cm−2) without mask, respectively.
