Abstract

A general doping strategy, using a wide range of acids with different pKa values as additive, is demonstrated to enhance the conductivity of spiro-OMeTAD, the dominant hole transport material in perovskite solar cells (PSCs). Hysteresis-less planar PSCs with ~19% efficiency and better open-circuit voltage and fill factor is achieved with acid doped spiro-OMeTAD.
