Abstract

A new spirobifluorene-based hole-transporting material (spiro-tBuBED) was efficiently synthesized on the gram scale via straightforward C-H activations/arylations. Perovskite solar cells with spiro-tBuBED showed a promising power conversion efficiency of 18.6% without a device oxidation process previously considered to be indispensable.
