由于其普遍适用性，形成固溶体已成为改善各种热电材料性能的最有效策略。以p型FeNb1−xVxSb固溶体为例，表明固溶体的形成并不一定能改善热电性能。p型FeNb1−xVxSb的峰热电品质因子随V含量的增加而降低，与其他热电体系有明显不同。目前的结果表明，全面了解形成固溶体的多种影响对于开发高性能热电材料是重要的。
Forming solid solutions, due to its universal applicability, has been the most effective strategy for improving the performance of a wide variety of thermoelectric materials. Taking p‐type FeNb1−xVxSb solid solutions as an example, here it is shown that the formation of solid solutions cannot always improve the thermoelectric performance. The peakzTand thermoelectric quality factor of p‐type FeNb1−xVxSb decrease with increasing V content, remarkably different from other thermoelectric systems. The present results demonstrate that comprehensive understanding of the multiple effects of forming solid solutions is important for developing high‐performance thermoelectrics.
