Problems solved by technology

Among them, the thermoelectric nuclear battery has a large volume and is difficult to realize miniaturization; the radiant volt effect nuclear battery is easy to cause radiation damage due to the direct bombardment of radioactive particles on the semiconductor material; A large number of electron-hole pairs are generated inside the material, and the electron-hole pairs drift to both sides under the action of the built-in potential of the transducing device, and a large number of holes and electrons are collected on both sides of the battery, which can be generated by connecting the electrodes and the load. electric current
This method greatly reduces radiation damage. However, the traditional fluorescent photoelectric nuclear battery uses a fluorescent layer to generate fluorescence. Its two-dimensional structure is difficult to fully utilize the energy released by the radioactive source, and the generated light energy is also difficult to be fully collected. The conversion efficiency of this type of nuclear battery is greatly reduced, and the device is more complicated
