In this work, a lithium and silver co-doping strategy has been successfully implied to prepare NiOxfilms for high performance inverted planar perovskite solar cells (PSCs). Compared to the pristine and single-doped NiOx, the Li and Ag co-doping approach exhibits the synergistic effect and can endow NiOxfilms with higher electrical conductivity, higher hole mobility and better interface energy band alignment with perovskite active layers. Moreover, the perovskite film with enhanced crystallinity can be obtained induced by the Li,Ag:NiOxfilm. The PSC with Li,Ag:NiOxHTL shows a high power conversion efficiency (PCE) up to 19.24% and less hysteresis effect, which outperforms the devices with the pristine NiOxor single-doped NiOxHTLs. Meanwhile, the Li,Ag:NiOxdevice can retain 95% of its initial PCE after storage at the relative humidity of 30 ± 2% in 30 days without encapsulation. Our work demonstrates that lithium and silver co-doping is a promising route for realizing efficient p-type NiOxHTL, which provides a simple way to boost the efficient and stable of inverted planar PSCs.
