AB  - Compared to the traditional fullerene derivatives, non-fullerene acceptors show 
      more tunable absorption bands as well as adjustable energy levels which are 
      favorable for further PCE enhancement of organic solar cells. In order to enhance 
      light-harvesting property of dithienonaphthalene (DTN)-based acceptors, we 
      designed and synthesized two novel non-fullerene acceptors (DTNIF and DTNSF) 
      based on a ladder-type DTN donor core flanked with two different acceptor units. 
      In combination with a benchmark wide bandgap copolymer (PBDB-T), the best 
      performance device based on DTNIF displayed a high PCE of 8.73% with a 
      short-circuit current (J (sc)) of 13.26 mA cm(-2) and a large fill factor (FF) of 
      72.77%. With a reduced bandgap of DTNSF, the corresponding best performance 
      device showed an increased J (sc) of 14.49 mA cm(-2) although only a moderate PCE 
      of 7.15% was achieved. These findings offer a molecular design strategy to 
      control the bandgap of DTN-based non-fullerene acceptors with improved 
      light-harvesting.
