摘　　要：依据热光伏电池结构组成和工作原理,建立相对应的单片热光伏电池表面电流流动的二维有限元模型。为了验证模型的可靠性,搭建单光谱高能流辐射测试平台,进行实际辐射条件下热电转换性能的测试和验证。结果表明:在入射光斑大小保持不变时,随着入射辐射能量增加,热光伏电池的输出功率增加,且入射辐射能量对短路电流的影响与入射辐射能量呈线性增加,约为1.25倍,但对开路电压的影响很微小,约为1.02倍;在入射能量一定,光斑大小发生改变时,短路电流也会随着光斑的增大而增大,但开路电压保持不变,电池的输出功率增加。应尽可能增大电池的工作区域,以提升电池的性能。Based on the structural composition and working principle of thermophotovoltaic cells,establish a two-dimensional finite element model for the surface current flow of a single thermophotovoltaic cell.To verify the reliability of the model,a single spectral high-energy flux radiation testing platform was built to test and verify the thermoelectric conversion performance under actual radiation conditions.The results show that when the size of the incident light spot remains constant,as the incident radiation energy increases,the output power of the thermophotovoltaic cell increases.The impact of the incident radiation energy on the short-circuit current increases linearly with the incident radiation energy,about 1.25 times,but the impact on the open-circuit voltage is very small,about 1.02 times.When the incident energy is constant and the size of the diameter changes,the short-circuit current also increases with the increase of the spot,but the circuit voltage remains unchanged,and the output power of the cell increases.The working area of the cell should be increased as much as possible to improve the performance.
