Optoelectronic Properties of a Benzodithiophene-Based Organic Photovoltaic

Benzo[1,2-b:4,5-b′]dithiophene (BDT) contains electron donating groups and conjugates with acceptor material as a donor-acceptor type conjugated polymer, which can be applied in bulk heterojunction organic photovoltaics due to its high charge carrier mobility. In this study, we used Stille coupling polymerization to synthesize a BDT monomer with thiophene side-chains and copolymerized with dioctyl 2,5-dibromoterephthalate (DTP) to form a 2-D...
