Abstract

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.
