In this paper, we propose a new design and comprehensive optimization process for improving the diffraction gratings used as the back reflector of silicon solar cells. For this process, the optimum refractive index and its corresponding available material which can be used as the grating material has been chosen as 1.57 and SiO2, respectively. Also, all of geometric parameters which affect the performance...
In this paper, we have used detailed balance limit model in order to achieve optimum single junction solar cell for different outdoor conditions. Also, maximum achievable efficiency for GaAs-based double junction solar cells has been calculated and effects of the concentration ratio on optimum point have been investigated. Although 1.9/1.0 eV is achieved as the optimum combination of band gaps for...
