Abstract

Dihydronaphthyl-based [60]fullerene bisadduct derivative, NC₆₀BA, was synthesized at mild temperature in high yield. NC₆₀BA not only possesses a LUMO energy level 0.16 eV higher than PC₆₁BM but also has amorphous nature that can overcome thermal-driven crystallization. The fabricated P3HT:NC₆₀BA-based polymer solar cells exhibit superior photovoltaic performance and thermal stability compared to PC₆₁BM-based devices under the same conditions.
