چکیده انگلیسی
⺠Two sets of novel co-polymers based on dithieno[3,2-b:2â²,3â²-d]]thiophene (DTT) derivative as a donor (D) and benzothiadiazole (BT) as an acceptor (A) were synthesized for BHJ solar cells. ⺠Structure activity relationship was discussed using D-Ï-A strategy in the polymer backbone. ⺠Incorporation of thiophene units as shorter conjugated spacers between donor and acceptor units facilitated tuning of the band gap and energy level with significant enhancement in the solar cell efficiency. ⺠DTT bridged with thiophene as a conjugated spacer appears to be a promising, quite simple, and useful co-monomer building block for photoactive polymer materials with solar cell applications.
