In recent years, increasing focus on environmental sustainability and the circular economy has sparked a resurgence of interest in incorporating eco-friendly and recyclable materials across numerous industries. Creating advanced dye-sensitized solar cells (DSSCs) employing natural dyes has a significant impact in fulfilling the need for environmentally sustainable technologies. In this study, we use MATLAB to examine the electrical features of DSSCs. The study relies on a model of electron diffusion in a porous titanium dioxide thin film and the absorption coefficient of local dyes. These latter are extracted from grapes, pomegranates and Moroccan roses. In particular, we investigate the absorbance of pigments by a spectrophotometer and the electrical features of DSSCs. The findings indicate that the photovoltaic performance metrics, such as maximum power voltage, short-circuit current density, open-circuit voltage, and maximum power current, are superior for pomegranate dye compared to grape and Moroccan rose dyes. This superiority is attributed to the higher absorption coefficient of the pomegranate dye, which efficiently absorbs incident light and generates excitons.
