Abstract

Triarylamine compounds as a very good donor was used for dye-sensitized solar cells (DSSCs) has been widely applied. The different bridge and acceptor used will shows different power conversion efficiency. In this work, We synthesized two new dyes (D1 and D2) containing benzothiadiazole structure as dye-sensitized solar cells (DSSCs) with 3,4-(ethylenedioxy)thiophene bridged, a donor of triphenylamine and an acceptor of cyanoacrylic acid. D2 compared with D1 adds a phenyl ring. Compounds 6 and 7 were synthesized via Still coupling reactions. Comparing with dye-sensitized solar cells (DSSCs) based on dye D1, the dye-sensitized solar cells (DSSCs) based on D2 exhibited a significant enhancement of cell performances. A power conversion efficiency of 7.7% was achieved for dye-sensitized solar cells (DSSCs) based on D2, which was much higher than that for dye-sensitized solar cells (DSSCs) based on D1 (0.9%). D2 through introducing a -conjugated spacer unit (phenyl ring) between the benzothiadiazole unit and the cyanoacetic acid group shows outstanding performance
