    Perovskite-based solar cells are involved in solar cell production as they enhance power conversion efficiency. The stability and performance of cells are mainly reliant on the materials used as hole transportation materials. One of the vital constituents of the perovskite solar cells is hole transporting layer. The supreme hole transporting material is the one that retains high hole mobility, durable air and mechanical stability and should have energy levels that are a suitable match with the perovskite layer. Lignocellulose (LC) fiber is reflected as a very abundant, eco-friendly, lightweight natural fiber and a biocompatible polymer. In this work Lignocellulose (LC) fiber is used as a substrate. As hole transporting materials (ETM) for perovskite solar cells, many kinds of semiconductor materials can be employed. In this research work, NiO is used as hole transporting material (HTM) due to its superior electrical properties, long-term mechanical and air stability, high hole mobility, and high conductivity. To enhance the properties of NiO thin films and also increase the power conversion efficiency of perovskite solar cells, Cu was added into it as a dopant. Cu-doped NiO (Cu:NiO) has a high conductivity compared to pure NiO. X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Ultraviolet-Visible Spectroscopy (UV-Vis), were carried out to characterize the synthesized material. It was indicated that Cu:NiO has better efficiency as a pure NiO when used as hole transporting material (HTM) in the Perovskite solar cells (PSC).
