The alloy donor strategy leverages both complementary polymer donors to enable highly efficient and stable ternary organic solar cells

WDWeihao DuZZZhongxin ZhouJSJunfeng Sun

Key Points

  • This research aims to explore the use of complementary polymer donors in enhancing the efficiency of ternary organic solar cells.
  • Fabricated organic photovoltaics using J71 and PBDTTS-2FQx as donors and IT-4F as the acceptor.
  • Conducted tests on binary devices based on J71:IT-4F and PBDTTS-2FQx:IT-4F.
  • Binary devices achieved power conversion efficiencies (PCEs) that demonstrated substantial improvement.
  • Results indicate enhanced stability in ternary organic solar cell configurations.

Abstract

Herein, organic photovoltaics (OPVs) were fabricated using J71 and PBDTTS-2FQx as donors and IT-4F as the acceptor. Binary devices based on J71:IT-4F and PBDTTS-2FQx:IT-4F achieved power conversion efficiencies (PCEs) of...
