Abstract

A new four-armed molecule Th4(DTPAB) with a triphenylamine–benzothiadiazole–triphenylamine unit as the core and 4-hexylthiophene as arms was synthesized. Solution-processed organic solar cells based on blends of Th4(DTPAB) and PC71BM demonstrate a power conversion efficiency of 3.18% with a high open circuit voltage of 0.96 V.
