Ni,Ti-co-doped MoO2 nanoparticles with excellent moisture stability and improved conductivity are synthesized via solvothermal cracking process for hole transporting material (HTM) in metal halide perovskite solar cells (MHP SCs). The Ni,Ti-doped MoO2 has similar oxidation state with pristine MoO2, but has better reduction stability than the MoO2 due to the weaker electronegativity of Ni and Ti than the Mo. Accordingly, the Ni,Ti-co-doped MoO2 HTM based MHP SC has 18.1% of power conversion efficiency at 1 sun (100 mW/cm2) condition. In addition, the un-encapsulated Ni,Ti-co-doped MoO2 HTM based MHP SC has 12-13% degradation after stability test under 85 °C/60% relative humidity for 20 days.
