Abstract

We employed ternary blends capable of energy transfer—a synthesized small molecule (SM-4OMe) comprising benzodithiophene (BDT) units (a molecule designed for energy transfer), and a polymer (PTB7-TH) with BDT units with desired packing orientation, and a fullerene—as active layers for single junction photovoltaic devices.
