| Hazard Information | Back Directory | [Uses]
Monomer for synthesis of polymers for high power conversion efficiency (PCE) organic solar cells and high mobility OFETs.
Fluorination lowers the polymer HOMO level; resulting in high open-circuit voltages well exceeding 0.7 V.
High-Efficiency Polymer F-PCPDTBT:PC70BM Bulk Heterojuction Organic Solar Cells (OPVs):
- JSC = 14.1 mA/cm2
- VOC = 0.74 V
- FF = 0.58
- PCE = 6.2%
