| 제목 | Scalable synthesis of Ti-doped MoO 2 nanoparticle-hole-transporting-material with high moisture stability for CH 3 NH 3 PbI 3 perovskite solar cells |
| 초록 | Ti doped MoO 2 nanoparticles with high BET surface area of 135 m2/g were synthesized via scalable solvothermal cracking of polycrystalline MoO 3 microparticles prepared by ultrasonic spray pyrolysis. The pristine MoO 2 and Ti doped MoO 2 nanoparticles showed metallic conductivity, whereas the MoO 3 microparticles had semi-conducting behavior. In addition, the Ti doping in MoO 2 nanoparticles formed stronger Mo-O bond than the pristine MoO 2 and consequently exhibited improved stability against humidity. Accordingly, the p-i-n type planar CH 3 NH 3 PbI 3 perovskite solar cells with Ti doped MoO 2 inorganic hole transporting material showed 15.8 % of power conversion efficiency at 1 Sun condition (100 mW/cm2) and significantly improved humidity stability |
