针对PN结型换能器件收集效率低，短路电流小等缺点，首次提出NPN结型核电池换能结构。用电子束对设计制作的NPN结型换能器件进行双面辐照实验，实验结果表明NPN结型换能结构能够通过降低P区掺杂浓度提高耗尽区宽度，减小换能器件厚度降低体电阻，增大短路电流，获得较大的能量转换效率。

Because the nuclear microbattery based on silicon PN junction suffers from small short-circuit current and can not achieve high collection efficiency,this paper raises for the first time that silicon NPN junction as the energy conversion structure for nuclear battery is expec-ted to achieve higher electrical power output. The double-sided of silicon NPN diode were irra-diated by electron beam and the electrical capabilities are measured during the irradiation. The experiment results indicate that NPN junction can increase depletion region width by lightly do-ping of P region,and reducing the thickness of batter to achieve a small body resistance,which result in the short-circuit current and energy conversion performance improving.
