Nickel oxide morphology synthesized with a hydrothermal method for inverted perovskite solar cells.

In this paper, a hydrothermal method is used to synthesize a nickel oxide nanostructure (nano-NiO) for its application to inverted perovskite solar cells. These pore nanostructures were employed to increase both the contact and channel between the hole transport and perovskite layers of an ITO/nano- / / / device. The purpose of this research is twofold.
