제목 Synthesis and Characterization of Small Molecules based on Indacenodithieno[3,2-b]thiophene with Chromone Derivatives and their Photovoltaic Properties
초록 Indacenodithieno[3,2-b]thiophene(IDTT) and chromone derivatives, SMD1(without fluorine) and SMD2(with fluorine), based on conjugated small-molecule-donor materials were designed for organic solar cells. In this research, we synthesized materials which consist of the chromone derivatives as an electron-accepting group combined with IDTT, which has the effective form of push-pull structure in order to enhace the intramolecular charge transfer and the optical absorption of materials. The device performance of the materials end-capped with chromone derivatives containing fluorine shows higher efficiency than the one without fluorine. The HOMO/LUMO energy levels of the SMD1 and SMD2 were -5.33/-3.56 and -5.39/-3.50 eV. The power conversion efficiencies of SMD1/PC71BM and SMD2/ PC71BM in inverted organic solar cells were 1.03% and 2.23%, respectively.
