Problems solved by technology

The β volt effect nuclear battery uses the energy of β particles to form electron-hole pairs in the PN junction region of the semiconductor. Under the built-in electric field, the electrons flow to the N region, and the holes flow to the P region to form a current. The β volt effect nuclear battery generates The current is large and the energy utilization rate is high, but the semiconductor used as a transducer is susceptible to crystal damage caused by radiation, which reduces the efficiency
