New Donor-Acceptor Copolymer Containing Dialkoxy Naphthalene and Carbonylated Thieno[3,4-b]thiophene for OTFT and OPV |
| 초록 |
A new copolymer (PONTET), composed of dialkoxy napthalene as a donor and a carbonylated thieno[3,4-b]thiophene group as an acceptor, was obtained by Suzuki coupling polymerization. The number average molecular weight (Mn) of PONTET is 6.4 kg mol-1 with a polydispersity index of 1.20, determined by gel permeation chromatography using chloroform. PONTET showed broad absorption with maximum at 534 nm in solution and 618 nm in a thin film, respectively. The hole mobility of PONTET was 1.5 × 10-3 cm2/Vs and the Ion/Ioff ratio was 7.7 × 104. The best performance of the solar cell using PONTET was obtained at a PONTET:PC70BM blend ratio of 1:4. The maximum power conversion efficiency of a PONTET based solar cell reached 1.3% with an open circuit voltage (Voc) of 0.56 V, a short circuit current density (Jsc) of 5.6 mA/cm2, and a fill factor (FF) of 41.3%. |
