Abstract
Base optimum thickness is determined for a front illuminated bifacial silicon solar cell n+-p-p+ under magnetic field. From the magneto transport equation relative to excess minority carriers in the base, with specific boundary conditions, the photocurrent is obtained. From this result the expressions of the carrier’s recombination velocity at the back surface are deducted. These new expressions of recombination velocity are plotted according to the depth of the base, to deduce the optimum thickness, which will allow the production, of a high short-circuit photocurrent. Calibration relationships of optimum thickness versus magnetic field were presented according to study ranges. It is found that, applied magnetic field imposes a weak thickness material for solar cell manufacturing leading to high short-circuit current.

One major problem of silicon solar cells is the small collection of minority charge carriers which may be due among others at short diffusion lengths and carrier’s mobility and surfaces recombination velocity issues
We present a method to determinate the optimum thickness (Hopt) of silicon solar cell under external conditions i.e. magnetic field (B) and polychromatic illumination
Summary
One major problem of silicon solar cells is the small collection of minority charge carriers which may be due among others at short diffusion lengths and carrier’s mobility and surfaces recombination velocity issues. The phenomenological parameters to be determined are, diffusion length (L), diffusion coefficient (D), lifetime (τ), surface recombination velocities respectively at the junction (Sf) and the rear (Sb) [20] [21] [22] [23] [24]. The applied external conditions such as, radiation flux and energy [27], temperature and magnetic field [28] [29] [30], influence the phenomenological parameters. We present a method to determinate the optimum thickness (Hopt) of silicon solar cell under external conditions i.e. magnetic field (B) and polychromatic illumination
