本文报道了Al_（0.52）In_（0.48）P Ni-63放射性同位素电池在-20 ℃ ~ 140 ℃温度范围内的性能。一个直径为400 μ m的p（+）-i-n（+）（2 μ m i层）Al_（0.52）In_（0.48）P梅萨光电二极管被用作新型β伏打电池中的转换器件。暗电流的测量结果表明，饱和电流增加的Al 0.52 In 0.48 P探测器上的增加的温度，而理想因子下降。详细研究了温度对电池关键参数的影响，结果表明：开路电压、最大输出功率和内转换效率随温度的升高而降低。在-20 ° C下，分别测量到0.52V和0.28pW的开路电压和最大输出功率。出版社：AIP Publishing
In this paper, the performance of an Al0.52In0.48P Ni-63 radioisotope cell is reported over the temperature range of -20 degrees C to 140 degrees C. A 400 mu m diameter p(+)-i-n(+) (2 mu m i-layer) Al0.52In0.48P mesa photodiode was used as a conversion device in a novel betavoltaic cell. Dark current measurements on the Al0.52In0.48P detector showed that the saturation current increased increasing the temperature, while the ideality factor decreased. The effects of the temperature on the key cell parameters were studied in detail showing that the open circuit voltage, the maximum output power, and the internal conversion efficiency decreased when the temperature was increased. At -20 degrees C, an open circuit voltage and a maximum output power of 0.52V and 0.28 pW, respectively, were measured. Published by AIP Publishing.
