A benzotriazole and 3-hexylthiophene (3HT) bearing a donor acceptor donor (D-A-D) type conjugated polymer (PHTBT) was synthesized. The polymer is both p and n-dopable, fluorescent, soluble in common organic solvents, and processable. Electrochemical and spectroelectrochemical characterization of PHTBT and its photovoltaic performance in organic bulk heterojunction (BHJ) solar cells (SC) have been measured. Using PHTBT as donor material in BHJ solar cells resulted in increased open circuit voltage (V-oc) up to 0.85 V.
