Abstract: In this work, a theoretical study of the effect of the magnetic field on the minority charge carrier density and the diffusion capacity of a silicon solar cell with vertical junction in series in dynamic frequency regime, is done. From the relative continuity equation of the minority charge carriers’ density we establish the boundary condition at the junction and the base medium. The expression of the density of minority carriers of charges in the base, allows us to determine the capacity of diffusion of the solar cell according to the magnetic field, the frequency of modulation, the wavelength of illumination and a junction recombination velocity. The profile of the diffusion coefficient allowed us to make a choice on the values of the magnetic field. These values of the magnetic field intensity will be fixed throughout this article. Each value of the magnetic field strength corresponds to a well-defined value of the resonance frequency. We obtained two ranges of illumination wavelengths from the minority charge carrier’ density profile. The influence of the magnetic field on the diffusion coefficient, of the density of minority charge carriers in short-circuit and open-circuit conditions and of the diffusion capacity, for a specific wavelength, is theoretically studied.

Abstract: When light is incident on the interface of different media, refraction and reflection occur. Also, while light propagates through a medium, scattering by particles constituting the medium is a well-known basic property. Recently, the non-classical phenomenon is expected to be the core of many technologies such as resonantly transfer energy, nanosized quantum optical energy amplifiers, and nano-sensing technique. This technique uses a surface plasmon induced by the reconfiguration of the distribution of electrons in a metallic material by stimulation of an external field. This is because, in the nanoscale structure of the medium, the light intensity distribution in the medium is changed by the interaction of the fields in the medium including the surface plasmon. In this study, the light transmission characteristics of the metal material array medium with a size smaller than the skin-depth were investigated by 3D simulation of the FDTD method. The light intensity distribution and light transmittance of the light passing through the medium of the metal (Au) cylinder and sphere array structure were analyzed. The synergistic effect of light transmittance appeared as the light spread was reduced due to the interaction between metal materials. In addition, when light is incident on the interface in an oblique direction, the beam peak is split into several parts.
