摘要

初步设计制作3种辐射伏特效应同位素电池换能单元

测试其在固态63Ni源和3H源辐照下的输出电特性

对输出电特性进行数学解析模型分析并提出进一步改进设计的思路。结果表明

设计的换能单元在发射高能α同位素作用下

性能快速急剧退化;在2.96×108Bq的63Ni源辐照下

获得最大短路电流为28.4nA

最大开路电压为0.267V;在约5.09×109Bq的3H源辐照下

获得最大短路电流为62.8nA

最大开路电压为0.260V。当前换能单元参数还需进一步优化。

Abstract

Based on the principle of radiation-voltaic effect

a preliminary energy-conversion unit of radiation-voltaic battery was designed.Three energy-conversion units were manufactured and their electric I-V properties under irradiation of solid sources of 63Ni and 3H were measured.The I-V curves were analyzed and some ideas for improvement were presented.It was found that the designed energy-conversion unit deteriorated dramatically under irradiation of 241Am source.The best Uoc and Isc gained under irradiation of 2.96×108 Bq 63Ni were 0.267 V and 28.4 nA

and were 0.260 V and 62.8 nA under irradiation of a 5.09×109 Bq 3H source.Further efforts are being made to improve the design.
