State-of-the-art methodologies for the conversion of solar thermal power to electricity are based on conventional electromagnetic induction techniques. If appropriate ZT = 4 thermoelectric materials were available, it is likely that conversion efficiencies of 30-40% could be achieved. The availability of all solid state electricity generation would be a long awaited development in part because of the elimination of moving parts. This paper presents a preliminary examination of the potential performance of ZT = 4 power generators in comparison with Stirling engines taking into account specific mass, volume and cost as well as system reliability. High-performance thermoelectrics appear to have distinct advantages over magnetic induction technologies.
用于将太阳能热能转换为电能的最先进方法基于传统的电磁感应技术。如果有适当的 ZT=4 热电材料，那么转换效率可能达到 30-40%。全固态发电的可用性将是人们期待已久的发展，部分原因是消除了运动部件。本文初步研究了 ZT=4 功率发生器与斯特林发动机的潜在性能，考虑了比质量、体积和成本以及系统可靠性。高性能热电材料似乎比磁感应技术具有明显的优势。
