NiOx thin films prepared by liquid phase deposition (LPD) method for hole transport layers in inverted perovskite solar cells
Nickel oxide (NiOx) thin films were prepared by liquid phase deposition (LPD) mehod and applied as hole transport layers (HTLs) in inverted perovskite solar cells (PSCs). The as-deposited α-3Ni(OH)2 · 2H2O films with porous nanoflake morphology were converted to NiOx by heat treatment at 500 °C. The heat-treatment dura...
