Allgemeine Beschreibung

Poly([2,6′-4,8-di(5-ethylhexylthienyl)benzo[1,2-b;3,3-b]dithiophene]{3-fluoro-2[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (PTB7-Th) is a semiconducting polymer with a narrow band gap of 1.59 eV and an absorption peak at 780 nm. The devices fabricated from PTB7-Th have been shown to have higher output voltage and short circuit current density than PTB7.

Anwendung

High-Efficiency Organic Solar Cells (OPVs)

OPV Device Structure: ITO/PEDOT:PSS/Polymer:PC71BM/ Al

  • JSC = 19.8 mA/cm2 \
  • VOC = 0.79 V
  • FF = 0.65
  • PCE = 10.12%
PTB7-Th is mainly used as an active layer in organic solar cells (OSCs). It forms a blend with different acceptor materials which include PC71BM, ICBA, and PCBM to potentially improve the power conversion efficiency (PCE) of the OSCs.
