Spectral Properties of GaAs Cell Under the Space Irradiation

GaAs solar cell is the most important source of energy of satellite to maintain the steady working. Irradiation of electron and ozone will affect the performance of the GaAs solar cell. This paper is focused on the variety of spectral properties of GaAs cell under space irradiation. The surface structure is constructed according to the interaction between the solar surface and irradiation electron and atomic oxygen. Then the effect of erosion of structured surface on the spectral properties of GaAs cell is discussed. The variety of the spectral with the change of parameters of rough surface is investigated, which can be a good candidate for satellite design.
