Abstract

In this work, a non-fullerene acceptor molecule (ITIC-FOR) based on heptacyclic (indacenodithieno[3,2-b]thiophene) IDTT as the core with F-phenylalkoxy (FOR) as a side chain was designed and synthesized. The photovoltaic properties of the HFQx-T:ITIC-FOR based non-fullerene polymer solar cells (NF-PSCs) were explored. By device optimization, a good power conversion efficiency (PCE) of 7.33% was obtained.
