Abstract

Nickel oxide (NiO_x) is promising hole transport material for efficient and stable lead halide perovskite solar cell (PSC) due to its promising optoelectronic properties and superior moisture resistivity. Herein, we investigate the effect of surface treatment of sputtered NiO_x film using ethanol (NiO_x-EtOH) in device parameters of PSC. Ethanol treatment of NiO_x facilitates the growth of high-quality perovskite film (larger grain size, better crystallinity, and faster carrier injection). The device with NiO_x-EtOH demonstrated the champion power conversion efficiency of ∼13.52% (with open circuit voltage (V_OC) ∼1.075 V) of 1 cm² large-area device. While the device with pristine NiO_x has a device efficiency of 11.78% (with V_OC ∼0.99 V). This report corroborates that the PSC with NiO_x-EtOH improves device performance owing to hydrophilicity, defect passivation of sputtered NiO_x surface, and attenuation of recombination in the perovskite bulk.
