Abstract

A set of two donor− acceptor type conjugated polymers with carboxylic acid side groups have been synthesized and utilized as active materials for dye-sensitized solar cells (DSSCs). The polymers feature a π-conjugated backbone consisting of an electron-poor 2, 1, 3-benzothiadiazole (BTD, acceptor) unit, alternating with either a thiophene− fluorene− thiophene triad (2a) or a terthiophene (3a) segment as the donor. The donor− acceptor ...
