Numerical simulation of dye-sensitized solar cells performance for local natural dyes

Abstract

In this work, the characteristics of dye sensitized solar cells (DSSCs) have been studied by using MATLAB based on the electron diffusion model in a porous semiconductor of Titanium dioxide (TiO2) thin film. The numerical study was carried out by using the absorption coefficient of two different moroccan local pigments extracted from olive leaves and red moroccan hibiscus flower. The internal parameters were taken from previous research. The characteristics of cells have been calculated and showed that olive leaves have high photovoltaic performance than the red moroccan hibiscus flower.
