Abstract

A new type of photovoltaic cells is described. The DSSC is modeled using the analytical solution for the semiconductor transport equations of the simple diode. The model includes the effect of the cell shunt conductivity (sigma_sh) and series resistance of the cell (R_ser). The solar cell parameters are extracted from experimental results under different illumination levels. The cell parameters are characterized in terms of illumination intensity. The results show a good agreement of the model to fit the experimental data. Current-voltage characteristics, efficiency and fill factor of the DSSC are investigated at different illumination levels.
