IDIC is a non-fullerene acceptor with an A–D–A architecture, comprising an electron-rich indaceno[1,2-b:5,6-b′]dithiophene (IDT) core and two electron-deficient indanone–dimalononitrile end groups. It exhibits strong absorption across 500–800 nm with a high extinction coefficient of 2.4 × 10⁵ M⁻¹ cm⁻¹ and electron mobility up to 1.1 × 10⁻³ cm² V⁻¹ s⁻¹. In polymer solar cells, as-cast PBDB-T1:IDIC blends achieve power conversion efficiencies (PCEs) of 8.71% without further treatment. Ternary organic solar cells with PM6 donor and IDIC:TOBDT as dual acceptors have reached efficiencies of 14%, underscoring IDIC’s role in high-performance OSC design.
