General description

DTS(FBTTh2)2 is a conductive polymer that can be used as a donor molecule. It has a narrow band gap and shows a maximum power conversion efficiency of 7.0%. Its photostability is more than that of P3HT.

Application

Narrow band gap material for high-efficiency organic solar cells (OPVs) application
OPV Device Structure: ITO/MoOx/DTS(PTTh2)2: PC70BM/Al
  • JSC = 12.8 mA/cm2
  • VOC = 0.81 V
  • FF = 0.68
  • PCE = 7.0%
DTS(FBTTh2)2 can be used as a conjugating polymer that forms a donor-acceptor system with acceptor molecules such as perylene diimide, PC71BM and other fullerenes for the fabrication of bulk-heterojunction based solar cells.
