Abstract

Small molecule BODIPY dyes incorporating conjugated substituents at the β sites have been synthesized. Solution processed inverted bulk heterojunction cells were fabricated from the blends of the dyes and PC(71)BM. The cells exhibited very high open-circuit voltages (>0.9 V) and a high conversion efficiency of 3.22% has been achieved.
