In a beta radioluminescence nuclear battery, the beta energy is converted to light with the phosphor material, and then to electricity via photovoltaic cells. A method to optimize the thickness of phosphor layer is established in this study; the match between the luminescence spectrum and the photovoltaic cell is analyzed. The optimal parameters and output performance of the nuclear battery based on a sandwich-structure Pm-147/ZnS:Cu/photovoltaic cell are determined with the MCNP, transport theory of light, and detailed balance limit of efficiency. The battery prototypes are fabricated and tested, and the experimental optimal thickness matches that of the theoretical result well.
