Synthesis and characterization of small-molecule-dyes based on IDTT derivatives with CMCN moiety as electron acceptor group |
| 초록 |
In this study, we designed and synthetized two acceptor-donor-acceptor (A-D-A) type conjugated small molecules, denoted as IDTT-CMCN and IDTT-HT-CMCN, based on indacenodithieno[3,2-b]thiophene (IDTT) and 2-(2-methyl-4H-chromen-4-ylidene)malononitrile (CMCN) for being used as donor material in organic solar cells. In these A-D-A type small-molecules IDTT is the electron donating unit while CMCN is the electron-withdrawing unit. In comparison with IDTT-CMCN, IDTT-HT-CMCN has 3-hexylthiophene (HT) as a ∏-bridge unit between the IDTT and CMCN moieties to increase the solubility and extend the π-conjugation length. OSCs based on both of these donors and PC71BM as the acceptor were fabricated to investigate the effect of alkylthiophenes on the photovoltaic properties. As a result, the IDTT-HT-CMCN showed a power conversion efficiency (PCE) of 7.60%. |
