Highly Crystalline Low Band gap Polymers based on Fluorinated Quinoxaline for Photovoltaic Cells |
| 초록 |
A series of low band gap fluorinated quinoxaline based conjugated polymers were designed and synthesized. Due to the coplanarity of the polymeric backbone and strong intermolecular packing with pronounced crystalline morphology, as supported by DFT calculations and GIWAX analysis, the fabrication of PSCs based on PDFQx3T achieved power conversion efficiency (PCE) of over 7% with an open-circuit voltage (Voc) of 0.73V, a short-circuit current (Jsc) of 13.87mA/cm2, and a fill factor (FF) of 75%. Moreover, PDFQx3T could still maintain PCE of over 6% with film thickness of the active layer over 280 nm, which makes it a promising candidate for printed PSCs. This study provides an insight into molecular design for efficient semi-crystalline photovoltaic structures. |
