Paper Abstract

The exceptional photovoltaic properties demonstrated for organic-inorganic hybrid lead halide perovskites have attracted tremendous attention around the world. The intriguing optoelectrical characteristics include strong absorption coefficient, high carrier mobility and long charge diffusion length. The power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have now been boosted up to a certified 22.7% within a few years. Based on ambipolar type carrier transport properties of the perovskites, hole-conductor-free (HTMfree) PSCs have been developed, which simplifies the configuration of the devices. Previously, our group has developed a carbon based HTM-free printable mesoscopic PSC and achieved a certified PCE of 12.8 % with high stability. Herein, we reported a new hybrid carbon electrode based on ultrathin graphite/carbon black for HTM-free printable mesoscopic PSCs, and obtained a PCE of 13.83%.
