dc.description.abstract | We report a comparative study on the thermal-and microwave-assisted Stille-coupling polymerization of a benzodithiophene-based donor-acceptor polymer (PTB7). For this study, we synthesized PTB7 polymers through Stille-coupling polymerization under microwave conditions (M-PTB7, M-n = 75 kg mol(-1), and D = 2.2) as well as thermal conditions (T-PTB7, M-n = 31 kg mol(-1), D = 2.1). Although the microwave-assisted method increases the molecular weight of PTB7 in a short time, the power conversion efficiency of MPTB7 (2.8%) is lower than that of T-PTB7 (7.8%). The microwave-assisted method was found to generate more structural defects from homo-coupling side reactions, resulting in a decrease in J(SC) and FF values for M-PTB7. Our findings highlight the importance of controlling the generation of homocoupled units during the synthesis of PTB7 polymers for high-performance PSCs. | - |
