Synthesis and Characterization of IDTT Derivatives for Organic Solar Cell |
| 초록 |
New acceptor-donor-acceptor (A-D-A) type conjugated small-molecule-dyes, based on indacedithieno[3,2-b]thiophene (IDTT), named IDTT-OX and IDTT-EPMP-IDC have been synthesized and characterized for solution-processed bulk heterojunction organic solar cells (OSCs). These molecules contain IDTT as the donor moiety, OX (phenylisoxazolone) and EPMP-IDC (malononitrile derivatives) as the acceptor moeity. IDTT-OX exhibits a strong self-aggregation behavior and broad absorption with an optical band gap of 1.88 eV. While IDTT-EPMP-IDC shows effectively restricted self-aggregation due to the presence of the alkyl group at EPMP-IDC and it has 1.60 eV optical band gap. To evaluate the performance of these molecules as a donor, inverted-type OSCs based on the blend of IDTT-OX (or IDTT-EPMP-IDC) and PC71BM as an acceptor were fabricated. The power conversion efficiencies (PCEs) of the optimized OSCs for IDTT-OX and IDTT-EPMP-IDC reached up to 0.29% and 2.07%, respectively. |
