ABSTRACT: The photovoltaic (PV) cell
performances are connected to the base photogenerated carriers charge. Some
studies showed that the quantity of the photogenerated carriers charge
increases with the increase of the solar illumination. This situation explains
the choice of concentration PV cell (C= 50 suns) in this study. However, the strong photogeneration
of the carriers charge causes a high heat production by thermalization,
collision and carriers charge braking due to the electric field induced by
concentration gradient. This heat brings the heating of the PV cell base. That
imposes the taking into account of the temperature influence in the
concentrator PV cell operation. Moreover, with the proliferation of the
magnetic field sources in the life space, it is important to consider its
effect on the PV cell performances. Thus, when magnetic field and base temperature
increase simultaneously, we observe a deterioration of the photovoltage, the
electric power, the space charge region capacity, the fill factor and the
conversion efficiency. However the photocurrent increases when the base
temperature increases and the magnetic field strength decreases. It appears an
inversion phenomenon in the evolution of the electrical parameters as a
function of magnetic field for the values of magnetic field B＞ 4×10-4 T.
