제목 Photovoltaic Properties of A-D-A Small molecule-based on Indacenodithieno[3,2-b]thiophene with Chromone Derivative For Organic Solar Cells.
초록 We designed conjugated small-molecule-donor materials based on Indacenodithieno[3,2-b]thiophene (IDTT) and chromone derivatives, named SMD1 (without fluorine) and SMD2 (with fluorine) for organic solar cells. Effective ICT came from the powerful push-pull structure and when chromone derivatives as an electron-accepting group combined with IDTT increased optical absorption. The device performance of the small molecule end-capped with chromone derivatives with fluorine exhibits higher efficiency than the other one. When the devices processed additive DIO, the performance was decreased. The SMD1 energy levels were -5.33eV and -3.56eV, The SMD2 energy levels were -5.39eV and 3.50eV. The devices PCE of SMD1/PC71BM and SMD2/PC71BM without the addition of DIO were 1.03% and 2.23%
