Substituent Position Engineering of Phosphine Oxide Functionalized Triazine-based Cathode Interfacial Materials for Flexible Organic and Perovskite Solar Cells |
| 초록 |
The grand challenge involved in inverted organic solar cell (IOSC) and perovskite solar cell (PSC) technology is to control the interfacial losses at the interface of the photoactive layer with the electron extracting electrode. Herein, three organic small molecules, namely o-(F)-PO-TAZ, m-(F)-PO-TAZ and p-(F)-PO-TAZ, consisting of phosphine oxide (P=O) functionalized 1,3,5-triazine (TAZ) with a fluorine atom (-F) at the ortho (o)/meta (m)/para (p) positions of the phenoxy group attached to the TAZ unit are developed via a rational design approach and used as cathode interfacial layers (CILs) in flexible IOSCs and PSCs. We realized that the –F position particularly affects the glass transition temperature (Tg) of the PO-TAZ derivatives, which in turn exerts a positive effect by maintaining robust and smooth morphological features. This gives the IOSC and PSC devices an –F position-dependent performance. |
