Abstract

Perovskite solar cells (PSCs) show great potential as a replacement to traditional silicon-based solar cells due to their high productivity and low price. However, freshly inverted perovskite solar cells (IPSC) which is the inverted of PSC have gotten a lot of interest in recent years because of their consistent operational stability, reduced hysteresis, and low fabrication procedure. Among the materials used in p-type semiconductor, nickel oxide (NiO) is a material used in hole transport layer (HTL) due to its transparency and conductivity. But the problem is that while NiO contacts with perovskite it will cause low conductivity and unsatisfactory interface contact. So, the objective is to synthesis the NiO and doped NiO, and to characterize undoped and doped NiO as HTL in IPSC. As a result, the characteristics test for pure and doped NiO using ultraviolet-visible spectra (UV-Vis), scanning electron microscope (SEM), and X-ray Diffraction (XRD). From these results, it can be concluded that doped NiO is a potential material to replace pure NiO as HTL for IPSCs.
