A theoretical model of silicon solar cells with ultra-small textured surface has been established based on depletion approximation and drift diffusion theory. The ultra-small textured surface achieves the low reflectance by multiple reflections among the silicon nanowires (NWs). The electrical performances of the solar cells, including open circuit voltage (V oc), short circuit current (I sc) and conversion efficiency (η), are analyzed by the theoretical model. The results show that the low reflectance is not the only pursuit in manufacturing the Si NWs solar cells. Other factors including optimizing the surface passivation, improving the silicon wafers quality and designing the proper nanowire length should be considered together with NWs structure.
