自 20 世纪 80 年代中期洛克希德·马丁公司首次评估使用核电源的直接转换以来，热光伏 (TPV) 能量转换电池多年来取得了稳定且相当大的进展。对战略防御计划早期防御导弹卫星应用的设计交易和评估发现，电池技术还不成熟，电池效率低得令人无法接受，与热电技术相比，其效率低于 10%。三元化合物半导体外延生长技术、新颖的双异质结构结、创新的单片集成电池架构和带通串联滤波器的快速进步，共同将电池效率显着提高至 25%，并有望在不久的将来使用类似太阳能电池的多结方法将电池效率提高到 35%。最近 NASA 赞助的设计和可行性测试项目已经证明，100 We 放射性同位素电源在集成特定功率下可实现 19% 的系统效率。
Thermophotovoltaic (TPV) energy conversion cells have made steady and, over the years, considerable progress since first evaluated by Lockheed Martin for direct conversion using nuclear power sources in the mid 1980s. The design trades and evaluations for application to the early defensive missile satellites of the Strategic Defense Initiative found the cell technology to be immature with unacceptably low cell efficiencies comparable to thermoelectric of <10%. Rapid advances in the epitaxial growth technology for ternary compound semiconductors, novel double heterostructure junctions, innovative monolithic integrated cell architecture, and bandpass tandem filter have, in concert, significantly improved cell efficiencies to 25% with the promise of 35% using a solar cell like multijunction approach in the near future. Recent NASA sponsored design and feasibility testing programs have demonstrated the potential for 19% system efficiency for 100 We radioisotopic power sources at an integrated specific power o...
