A-D-A Small Molecules based on Indacenodithieno[3,2-b]thiophene as the Donor Materials with Chromone Derivatives for Organic Solar Cells |
| 초록 |
Conjugated small-molecule-donor masterials based on indacenodithieno[3,2-b]thiophene (IDTT) and the chromone derivatives, named SMD1 (without fluorine) and SMD2 (with fluorine), were synthesized for organic solar cells. The chromone derivatives as an electrone-accepting group, when combined with IDTT, can effectively form a powerful push-pull structure that induces effective ICT and enhanced optical absorption. The PCEs of the devices based on small molecule donors containing fluorine in the terminal accepting group showed higher performances. Furthermore, the PCEs of the devices containing DIO as a processing additive were dramatically decreased. The HOMO/LUMO energy levels of the SMD1 and SMD2 were -5.33/-3.56 and -5.39/-3.50 eV, respectively. The best performance based on SMD1/PC71BM and SMD2/PC71BM were 1.03% and 2.23% without the addition of DIO, respectively. |
