General description

2-((7-{4-[N,N-Bis(4-methylphenyl)amino]phenyl}-2,1,3-benzothiadiazol-4-yl)methylene)propanedinitrile (DTDCPB) is a donor-acceptor molecule which can be used in the fabrication of organic electronic devices such as organic solar cells (OSCs) and organic photovoltaics (OPVs).

Application

7.9% efficient vapor-deposited organic photovoltaic cells base on a simple bulk heterojunction

A vacuum-deposited organic solar cell employing this novel donor-acceptor-acceptor (D-A-A) donor molecule; DTDCPB; combined with the electron acceptor C60/ C70 achieved a record-high power conversion efficiency (PCE) of 6.8%.
Device structure:
MoO3 (30nm) / DTDCPB (7nm) / DTDCPB:C70 (40nm) / C70 (7nm) / BCP (10nm) / Ag (150nm)
Device performance:
  • JSC = 13.48 mA/cm2
  • VOC = 0.95 V
  • FF = 0.55
  • PCE = 6.8%
