Abstract

In this paper, a beta radioluminescent battery with different radioisotopes is studied, and different parameters of the proposed structure are optimized. These parameters include the luminescent layer thickness, the doping concentration in the semiconductor P-N junction, etc. Some of the parameters have an inverse effect on the battery outputs. So, a trade-off is sought between them to increase efficiency. Each part of the proposed structure is divided into much smaller parts in the simulations to ensure proper tracking of photons and the creation of electron holes in the semiconductor layer. Also, the passage of particles through each layer is carefully reviewed and calculated in terms of particle crossing percentage, their reflection percentage, rate of self-absorption, etc. Finally, the power, open-circuit voltage, and short-circuit current density of the proposed battery versus the main parameter changes are presented.

摘要

本文研究了一种具有不同放射性同位素的β射线发光电池，并对该结构的不同参数进行了优化。这些参数包括发光层厚度，半导体PN结中的掺杂浓度等。某些参数对电池输出有反作用。因此，在它们之间寻求权衡以提高效率。在仿真中，建议的结构的每个部分都分成了较小的部分，以确保正确跟踪光子并在半导体层中创建电子空穴。另外，还要仔细检查和评估粒子通过每一层的通道，并根据粒子穿越百分比，它们的反射百分比，自吸收率等进行计算。最后，功率，开路电压，
