ResumoThe effects of regioisomer and diastereomer separations of [70]PCBM on structures and photovoltaic properties of PffBT4T-2OD:[70]PCBM blend films have systematically been investigated for the first time. Decreasing the amount of a diastereomer of β-[70]PCBM with high aggregation tendency (β1-[70]PCBM) improved the photovoltaic performances.
