A high performance three-dimensional thiophene-annulated perylene dye as an acceptor for organic solar cells

Chem Commun (Camb). 2016 Sep 20;52(77):11500-11503. doi: 10.1039/c6cc05810h.

Abstract

A high performance three-dimensional (3D) thiophene-annulated perylene dye, namely tetra-PBI-S, was designed and synthesized. The appropriate LUMO level, balanced carrier mobilities and favourable phase separation make tetra-PBI-S based solar cells show a much higher power conversion efficiency (PCE) of 6.2% than tetra-PBI based solar cells with a PCE of 3.6%.
