    Flexible dye-sensitized solar cells (DSSCs) are a desirable alternative to rigid glass substrate-based solar cells because of the potential for flexibility and light weight. Researchers and scientists have been fascinated by polymer based electrodes due to its durability and flexibility. However, the production of polymers requires the use of hazardous chemicals. As a result, the tendency has shifted toward material synthesis methods that are safer, more affordable, and more sustainable. A flexible working electrode composite based on nickel (Ni) doped zinc oxide (ZnO) is synthesized in this project, by adding lignocellulose (LC) fibers. It is an effort to expand the potential of flexible electrodes based on metal oxide for DSSC applications. The co-precipitation process is used to create a transition metal-doped nanostructure (Ni doped ZnO). Doped particles with regulated composition, size, and homogeneity can be easily prepared at room temperature using this synthesis method. As a result, this work uses natural fibers to give Ni- doped ZnO a compact and porous structure for energy conversion applications. More sunlight will be absorbed as a result of the increased porosity, increasing the DSSC cell’s efficiency.
