λmax

640-646 nm in chloroform

Application

Used as a donor material in both vacuum-deposited and solution-processed OPVs.

Features and Benefits

  • Can be dissolved and solution processed and high extinction coefficient.
  • Intense absorption in the red/near-IR regions.

General description

2,4-Bis[4-(N,N-dibenzylamino)-2,6-dihydroxyphenyl] squaraine is used as an electron donor in solution processed organic photovoltaic (OPV) cells. This molecule increases the power conversion efficiency (PCE) of OPVs because it can harvest more photons in the low-energy range and also increases exciton dissociation, energy transfer and charge carrier transport in ternary blend films in bulk heterojunction polymer solar cells.
