Organic photovoltaics (OPVs) based on solution-processed conjugated polymers have attracted considerable attention because of their potential flexibility, inexpensive processing, and light weight. In particular, the bulk heterojunction (BHJ) architecture has enjoyed wide popularity due to the efficient light harvesting that such a microstructure affords. benzodithiophene(BDT) and alkylidenefluorene(AFO) derivatives have deep HOMO levels that increase the open-circuit voltage of the PSCs. Quinoxaline(Qu) unit is to incorporate chromospheres highly absorbing in visible and near-infrared regions. Thiophene spacer was introduced in polymer side chain for increasing charge transporting property and π-conjugation length. In this study, we synthesized Qu based copolymers and investigated their OPVs property. |
