Overview

Novel perylene diimide cathode interlayers improve electron extraction in organic solar cells, suggesting enhanced stability.

Key Points

  • Organic solar cells achieved a maximum power conversion efficiency of 20.36% using a new cathode interlayer.
  • Both PDINN-B2F and PDINN-B3F exhibited superior electron extraction compared to a control device with a PCE of 18.49%.
  • This study employs rational molecular engineering of cathode interlayers for enhanced performance and efficiency in OSCs.
  • Fluorinated CILs deliver excellent air stability and improved operational longevity for solar cells.
