报告摘要：

Nickel oxide (NiOx) films have been widely used as hole transport layers (HTLs) for inverted perovskite solar cells (PSCs) due to its high p-type conductivity, high optical transmittance and good chemical stability. The NiOx  films are deposited by pulsed laser deposition, and modulating the intrinsic  VNi defects of NiOx HTLs to adjust its optical and electrical properties via changing the oxygen partial pressure. The PSCs with undoped NiOx HTLs exhibit the power conversion efficiency (PCE) of 16.85% with negligible hysteresis behavior. Furthermore, the Cu-doped NiOx HTLs show the improved conductivity without sacrificing the optical transmittance, the PSCs with Cu:NiOx HTLs exhibit the high PCE of 20.41%, which is the best efficiency among the PSCs with physical vapor deposited NiOx HTLs.
