A-D-A Type Small Molecule Donors Capped with New Acceptor for Organic Solar Cells |
| 초록 |
Organic solar cells (OSCs) have been attracted considerable attention due to their unique properties as lightweight, flexibility and large area fabrication. Many researchers have been successfully developed polymer donor materials with high power conversion efficiencies (PCEs) such as PTB7 an so on. On the other hand, small molecule donors have potential to be good candidates to replace the polymer donor materials due to their easier energy level control, no batch-to-batch variations, and so on. In this work, we designed and synthesized new acceptor-donor-acceptor (A-D-A) type small molecule donors by using indacenodithieno[3,2-b]thiophene (IDTT) as donor unit and new electron accepting group containing malononitrile moiety. Herein, we fabricated the devices with small molecule donors and PC71BM as acceptor to investigated the photovoltaic properties. |
