    Banana peels are used as a preceding material in this investigation. It is dried, converted to bio Char, and then activated to generate activated carbon. Together with iron oxide, these components activated carbon powdered banana peel, and bio Char form a composite structure that aims to enhance the DSSC electrodes electro chemical characteristics. Because of its enormous surface area, porosity and conductivity, bio Char is a great substrate for introducing iron oxide nano particles. This improves DSSC stability and photo current production. According to the findings, the bio Char /iron oxide composite electrodes outperform pure bio Char and activated carbon electrodes in terms of power conversion efficiency and long-term stability. Through the efficient energy conversion of waste-derived materials for renewable energy technologies, this work presents a viable and cost-effective method for creating DSSC electrodes. Scanning electron microscopy (SEM) and x-ray diffraction (XRD) are two material approaches that have been used to assess the electrodes structural or morphological properties. The different functional groups contained in the produced electrodes have been identified using Fourier transform infrared spectroscopy (FTIR). The band gap is determined via UV-Vis spectroscopy through a Tauc plate. J-V plots and efficiency calculations are provided by the solar simulator.
