We have fabricated ternary blend solar cells by incorporating a wide-bandgap molecule, tris[4-(5-dicyanomethylidenemethyl-2-thienyl)phenyl]amine (TDCV-TPA), into a binary blend of a low-bandgap polymer, poly[2,3-bis-(3-octyloxyphenyl)quinoxaline-5,8-diyl-alt-thiophene-2,5-diyl] (PTQ1), and a fullerene derivative (PCBM) in order to enhance exciton generation and hence charge generation in the visible region. The ternary blend solar cells exhibited large external quantum efficiency (EQE) in the visible range as well as in the near-IR range.,As a result, the short-circuit current density (J(SC)) was improved by more than 20%.
