Abstract

Rational design of molecular acceptors for non-fullerene organic solar cells remains challenging. Here we show that the introduction of two simple methyl groups on a bithiophene-bridged perylene diimide dimer leads to two molecular acceptors with distinctly different properties and solar cell performance. This work contributes towards understanding the structure-performance relationship of high-performance molecular acceptors.
