Résumé

The solar cell is assumed to be under light concentration (C=50 Suns) which leads us to take into consideration the
electric field induced by electrons concentration gradient. We also take into consideration temperature influence on
electron and hole diffusion parameters, on carrier generation rate, on carrier intrinsic concentration and on silicon
energy gap. It emerges from results analysis that increase in temperature leads to decrease of open-circuit voltage
and the photovoltaic parameters at the maximum power point (MPP) such as electric power, photo-voltage and
photocurrent with however a slight increase of short-circuit photocurrent density. It also appears that temperature has a double effect on electrical parameters. The temperature dynamic effect which is characterized by parameters
variations linked to operating point displacement caused by temperature variations. And the temperature proper effect which is characterized by parameters variation with temperature at a given operating point. Thus, the combination of these two effects represents temperature effective effect.
