For this, the continuity equation relative to the photogenerated minority carriers in the base of the solar cell, in steady-state, is used. The resolution of this equation allowed us to determine the minority carriers¡¯ density according to the wavelength, the magnetic field and the junction recombination velocity. Based on the expression of minority carriers¡¯ density, we obtained the photoconductivity, the photocurrent density from which the spectral response and the quantum efficiency have been established according to the excitation and phenomenological parameters of the solar cell. We found that, as the magnetic field increases, both the spectral response and quantum efficiency decrease; this situation shows a degradation of the intrinsic properties of the solar cell. http://pubs.sciepub.com/ajmse/11/2/1/ajmse-11-2-1.pdf bifacial solar cell photoconductivity spectral response quantum efficiency magnetic field wavelength
