Using inorganic materials instead of organic materials as the hole transport material (HTM) for perovskite solar cells can be a way to improve the stability of these solar cells. As we illuminate the inverted solar cell from the HTM side, it is important to focus on the HTM layer. We have been developing the inorganic materials like NiO_x for improved properties as HTM. We found that the properties of perovskite solar cells with NiO_x HTM are very much dependent on the composition of NiO_x. And the composition of NiO_x can be easily controlled by changing the condition of sputter deposition, which is a cheap and easy method of thin film fabrication. The cell efficiency has been improved to 13.8% with good stability and reproducibility. The stability of the fabricated devices under continuous solar illumination and under ambient in dark condition is presented in Fig.1. NiO_x HTM is a good candidate to solve some critical issues like reliability, reproducibility and stability of the lead halide perovskite solar cells.
