Abstract
A new benzofuran-derived fulleropyrrolidine derivative denoted as FB-C-60 is synthesized by Prato single step synthetic protocol and successfully utilized as an electron acceptor in the bulk heterojunction organic solar cells (OSCs). The molecule possesses significant optoelectronic and redox properties, which are compatible with popular polymer donors. The OSCs constructed from PTB7/FB-C-60 blends yielded a highest power conversion efficiency (PCE) of 8.1%. The champion device that was fabricated from PTB7-Th/FB-C-60 bulk-composite film demonstrated a PCE of 9.6%, open circuit voltage of 0.83 V, series resistance of 3.3 Omega.cm(-2) and 75.1% of external quantum efficiency at 640 nm wavelength. A promising electron mobility of 1.2 x 10(-3) cm(2) v(-1) s(-1) of FB-C-60 is observed in the fabricated device. FB-C-60 shows the potential to positively replace the conventional PCBM to fabricate "cost-effective" high-performance OSCs.
