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) x cm(-1) of molar absorption coefficient at 458 nm and 459 nm of UV/vis(More)
We designed and synthesized the photosensitive π-conjugated organic dyes (CB-1, CB-2 and CB-3) with the carbazole substituted triphenylamine moiety as an electron donor unit and the cyanoacetic acid moiety as an acceptor for the application as a photosensitizer of dye-sensitized solar cells. The dyes with two carbazole units connected to triphenylamine(More)
