This work presents a three-dimensional study of bifacial silicon solar cell under intense light concentration and under constant magnetic field. This approach is based on the resolution of the minority continuity equation, taking into account the distribution of the electric field in the bulk evaluated as a function of both majority and minority carrier densities. In this approach, new analytical expressions of diffusion length, diffusion coefficient and excess minority carrier density was established for front illumination. The effect of magnetic field on excess minority carrier generation, carriers mobility, carriers density and electric parameters profile are then analysed.
