In this research work, for the first time, we introduced thin composite films (similar to 4.8 gm) made with NiO nanoparticles and single-walled carbon nanotubes (SWCNT) as alternatives to replace the commonly used carbon black/graphite counter electrode in full printable organic hole-transport layer free meso-porous perovskite solar cells. Due to the relative thick carbon black/graphite counter electrodes, which are typically 10 mu m thick, charge collection and batch to batch reproducibility of this type devices are significantly limited. We find an appreciated power conversion efficiency of 12.7% can be achieved for the CH3NH3PbI3 perovskite solar cell using mesoscopic TiO2/Al2O3 framework structure in combination with a thin NiO/SWCNT counter electrode under standard reporting conditions. Electronic impedance spectroscopy measurements reveal efficient charge collection ability for perovskite devices using thin NiO/SWCNT counter electrodes compared to the conventional carbon black/graphite counter electrode, and thus can efficiently deliver photocurrent.
