Résumé
The aim of this work is to study the electrical behavior of a vertical parallel junction silicon solar cell by
mean of impedance spectroscopy. By solving diffusion-recombination equation, the excess minority carrier density expression was established and the photocurrent and the photo voltage were deduced. We plotted Nyquist diagram of the solar cell impedance and gave corresponding electrical circuits. We then introduced impedance spectroscopy method to access for the first time to some electrical parameters of a vertical junction solar cell (series resistance,parallel resistance, capacitance and inductance).
