Key Points

  • To investigate how chlorination positions influence charge transport and efficiency in non-fullerene solar cell acceptors.
  • Designed dibenzo[b,f]oxepine-based acceptors with para and meta-chlorination.
  • Analyzed solid-state organization and intermolecular interactions.
  • Evaluated charge transport properties through experimental measurements.
  • Meta-chlorinated acceptor shows improved intermolecular packing compared to para-chlorinated.
  • Enhanced charge transport efficiency observed in meta-chlorinated configurations.

Abstract

Halogen positional isomerism provides an effective strategy to regulate the solid-state organization of non-fullerene acceptors. Two dibenzob,foxepine-based acceptors with paraand meta-chlorination were designed. Meta-chlorination enhances intermolecular packing and charge transport,...
