Title: Acid additives enhancing the conductivity of spiro-OMeTAD toward high-efficiency and hysteresis-less planar perovskite solar cells

Abstract

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